Communications Processor

Siemens has expanded its Simatic S7-400 controller to include the CP 443-1 OPC UA (unified architecture) communications processor. The processor uses the standardized OPC UA interface for the fast, direct exchange of data between automation components from different manufacturers. Users can install the CP 443-1 OPC UA as both a client and as a server, and so, for example, link a Simatic S7-400 to ERP systems. It is mainly used in Simatic S7-400 applications such as in the oil & gas industry.

As an OPC UA server, the new communications processor provides data of the Simatic S7-400, which OPC UA clients such as HMI (Human Machine Interface), MES (Manufacturing Execution System), ERP and SCADA systems can access (data access read, write and monitoring). This enables, for example, users to read production data such as vehicle data from an ongoing process and transfer it to ERP systems. Used as an OPC UA client, the processor collects and writes data to and from OPC UA servers. This facilitates, for example, communication with an OPC UA-compatible controller from another manufacturer. Users can configure the functions of the communications processor in the TIA Portal with the STEP 7 Professional V14 engineering software or in existing systems with STEP7 V5.5.

OPC UA is a standard for multi-vendor communication in the automation industry. The CP443-1 OPC UA supports OPC UA according to the specification 1.02. Integrated OPC UA security functions (for authenticating, authorization encrypting and signing data) minimize the risk of unauthorized data access.

Level Transmitter

Orion Instruments announced the release of the JUPITER Model Jm4 magnetostrictive level transmitter, its newest and most advanced level instrument to date. The Jm4 is available as a direct insertion option, as well as an external mount on any Orion magnetic level indicator (MLI) or modular instrumentation bridle. With an improved design, unparalleled performance, and a collection of new and innovative features, the Jm4 provides safer, simpler, and smarter measurement in total and interface level applications.

The Jm4 is engineered with numerous enhancements, including greater signal-to-noise ratio (SNR), a full graphic local user interface, HART 7.0 (Foundation fieldbus available), local waveform capture, and a more intuitive device type manager (DTM) allowing for remote configuration, trending, and diagnostics.

The JUPITER Model Jm4 also features Smart Probe technology. When any Jm4 transmitter head is attached to a probe, a single push of a button imports factory configuration settings into the head, and in seconds, the transmitter is ready for operation. JUPITER also offers a remote mount option. Available in 3- and 12-ft lengths, the transmitter head is attached to the probe via a flexible cable to allow for easier viewing under various spatial constraints.

Pyrometer and Imaging Portfolio

LumaSense Technologies Inc. added the integrated ISR 6-TI Advanced to their IMPAC pyrometer and imaging portfolio for increased control and optimization of manufacturing processes in metals, glass, and other materials industries. The ISR 6-TI Advanced is a true break-through by combining pyrometry with infrared imaging technology to produce “relative” thermal images. Relative thermal images are produced by measuring the temperature of the center spot with a ratio pyrometer and using an infrared filter to show an auto-calibrated thermal image based on the highly accurate ratio pyrometer temperature reading.

The system is based on the proven ISR 6 Advanced pyrometer and a video camera that utilizes a short wavelength infrared filter. The resulting ISR 6-TI Advanced system operates in a short wavelength (around 1 μm) for accurate and reliable temperature measurements between 700 °C and 1800 °C. The analog video output signal is converted to USB and fed to a PC using LumaSense’s InfraWin software. The InfraWin software generates and shows a relative thermal image from this signal. LumaSense’s InfraWin software also provides temperature, data logging, and analysis features. The ISR 6-TI Advanced paints a more-accurate picture for identifying potential issues before they lead to problems that impact process performance, a key benefit for materials manufacturers running heat-dependent processes.

Linear Position Sensors

H. G. Schaevitz LLC, Alliance Sensors Group has expanded its sensor product offering using LVIT Technology by adding the LZ-25 Series linear position sensors.

These are contactless devices designed for use in factory automation or assembly machinery applications where space is a premium, as well as for external mounting on hydraulic cylinders to sense rod position. These LVITs are offered in nominal full scale ranges from 50 to 900 mm (2 to 36 inches) with an excellent stroke-to-length ratio so that the sensor’s overall length is only about 38 mm (1.5 inches) longer than the linear range of the unit. The sensor has a 25.4 mm (1 inch) outside diameter aluminum or optional stainless steel body with a 1-m long radial exit cable for I/O connections. The 7.5 mm (0.295 inch) diameter through-bore of an LZ-25 provides clearance for its 6.35 mm (0.25 inch) diameter moving rod, which is made of the same material as its housing. This through-bore feature also means that the sensor is not subject to damage from typical mechanical overstroking.

Explosion Proof Cabinets

Intertec has launched a new range of explosion proof cabinets to protect field instrumentation operating in hazardous areas. Available in a diverse range of standard sizes, as well as in custom shapes up to walk-in shelter size, the cabinets are certified for use in Zone 1 and Zone 2 hazardous areas. They provide the possibility to install non-Ex rated analyzers and instrumentation inside Zone 1 or 2 classified environments.

Intertec’s pressurized explosion proof (Ex p) cabinets are constructed from GRP (glass reinforced polyester) composite materials. These materials are highly resistant to corrosion and have a similar strength to stainless steel, but are about 75 percent lighter, making them ideal for equipment containment and personnel shelter applications. They are especially suitable when robustness and rigidity need to be combined with low mass – such as on offshore platforms. They are also ideal for areas where there is a need to mitigate injury to personnel or damage to equipment, such as on sites where there is risk of an explosion.

Intertec is capable of producing single-piece panels of GRP composite as large as 6 x 12 meters. The pressurized cabinets are equipped with a control unit that regulates the flow of inert purging gas or compressed air, and then monitors the pressure inside the cabinet to ensure that it is maintained slightly above atmospheric pressure by automatically compensating for any leakage losses. Intertec works with a number of controls manufacturers to equip its Ex p cabinets with the most appropriate type of purging and pressurization systems.

Profinet Design & Simulation Software

Siemens is launching a new software tool on the market for the design and simulation of Profinet automation networks.

The Sinetplan network planner from Siemens is aimed at plant designers, constructors and operators and supports them from the planning stage, through commissioning to the operation of a Profinet communication network. In order to ensure subsequent operational reliability and to avoid problems during commissioning, the network is already designed with a suitable topological structure at the planning stage and any possible bottlenecks caused by peak loads, for example, are simulated. In the operating phase, Sinetplan offers transparency about the network capacity up to the port level of the individual stations by means of online scans, traffic shapers or reporting functions. This prevents unnecessary downtimes due to network overload and thus increases the availability of the network and the production. Faulty design or overloading of a Profinet network can compromise the overall application and, in the worst-case scenario, result in loss of production. Using the Sinetplan network planner it is possible to check the operational reliability of a Profinet network while it is still in the planning phase and find out whether a network is topologically suitable, what reserves the selected topological design offers and how you can protect the network against unforeseen peak loads (bursts).

Sinetplan is used in particular for the planning and operation of Profinet networks that use acyclic data services such as TCP/IP in addition to cyclic real-time communication. Projects already planned in Step 7 are easy to import, and existing systems are scanned online, verified and simulated.

Signal conditioner

Alliance Sensors Group has expended its line of LVDT/RVDT signal conditioner to include the SC-100 DIN-rail mountable AC-LVDT Signal Conditioner module that offers smart and fast LVDT setup with built-in null indication and simple front panel pushbuttons to set zero and full scale. The SC-100 is engineered to work with the widest range of AC-operated LVDTs, RVDTs, and inductive half-bridge position sensors and was specifically designed to be compatible with both Marposs and Solartron analog pencil gaging probes.

With an Alliance Sensors SC-100 AC-LVDT Signal Conditioner, an internal microprocessor eliminates the need to calculate jumper settings for gain, range, etc. The operator simply finds LVDT null, moves the LVDT’s core to one end of the range and then presses the zero button on the front panel. The operator moves the LVDT’s core to the other end of the specified range and presses the full scale button. The SC-100 is now fully calibrated with the LVDT or RVDT position sensor.

For installations where there are multiple LVDT position sensors, the SC-100s can be master/slaved to prevent beat frequency interaction between sensor signals. Should a master fail, ordinary LVDT signal conditioners in a master/slave hookup will revert back to their own oscillators, subjecting them to the beat frequencies the master/slave hook up was supposed to prevent. If an SC-100 master module were to fail, the auto-mastering feature causes another module to immediately become a new master for the slaves.

Linear Position Sensors

TE Connectivity (TE) announced the HLIR 750, 4-20 mA LVDT position sensors that are CSA listed for use in hazardous locations and where an intrinsically safe sensor is required. With stainless steel construction and a hermetically-sealed sensor body, these LVDT position sensors provide reliable contact-less position measurement for critical applications in gas turbines for fuel valve position feedback, vane pitch servo controls, governor controls, and generator shell expansion measurement.

Available in measuring ranges from ±2 inches to ±20 inches, HLIR 750 series intrinsically safe 4-20 mA LVDT position sensors feature high resolution, excellent repeatability, and low hysteresis. Maximum linearity error of these sensors is ±0.25% of full range output. Constructed entirely of stainless steel, position sensors feature a through-bore design that makes the core accessible from both ends for better mechanical support and core guidance and facilitates clean-out in dusty or dirty locations. Sensor lead wires exit through a radially-mounted 1/2-14 NPT male threaded conduit fitting for easy attachment to an explosion-proof junction box as well as rigid or flexible conduit.

AC-operated, the HLIR 750 series LVDT linear position sensors offer a 4-20mA output signal that allows users to run longer cables from a sensor to the control system with less worry of EMI or noise being induced on the signal. The analog signal can also be converted to digital output for use by today’s more complex process control systems.

Nuclear Power Temperature Sensors

CMR Group introduced a series of high performance temperature sensors for dedicated applications in the nuclear power industry.

CMR’s AN sensor series is designed for the temperature measurement of high pressure fluids and aggressive gaseous fluids used in nuclear power generation, although they can also be used effectively with non-pressurized fluids.

For more conventional measurement of ambient temperatures to very low or sub-zero levels in damp or refrigerated atmospheres, and ventilation ducts, the AMB sensor series is recommended.

These are the BS6 nuclear sensor with an insulated platinum resistance temperature detector (RTD) for use in harsh environments, and the special BCI6 type K thermocouple sensor for bearing temperature measurement on rotating/reciprocating machines.
