Wireless Network Module

Issue 2 and Volume 116.

The new WNM Wireless Network Module from Moore Industries is an accurate and reliable solution for sending process signals between remote field sites. The WNM provides a low-cost wireless communications link between field sites that are in rugged or impassable terrain, with a single unit transmitting for up to 30 miles and the ability to act as a repeater for a virtually unlimited transmission range.

The bi-directional WNM employs Spread Spectrum Frequency Hopping technology to avoid interference problems caused by crowded radio spectrums. This technology allows multiple radio networks to use the same band while in close proximity. Operating at standard operating frequencies of 902-928MHz or 2.4-2.4835GHz, the WNM does not require a regulatory license and can typically be installed without performing costly RF site surveys.

The WNM is easy to install and use, as it can be factory-configured to fit user specifications before being shipped.

Piezoelectric Accelerometer

Meggitt Sensing Systems, a Meggitt group division, has introduced the Endevco model 2226C, a compact and lightweight adhesive mounted piezoelectric accelerometer, designed for vibration testing of smaller structures and objects.

The Endevco model 2226C features a top-mounted 10-32 receptacle for easy installation within space-constrained environments. Units are designed to reliably operate over a temperature range of -67˚F to +350˚F. As a self-generating device, the model 2226C requires no external power source for operation. Although signal return is connected to the case, a user may isolate signal ground from the mounting surface by installing the unit with non-conductive adhesive.

Piston gauge

Fluke Calibration has introduced the PG9602 Piston Gauge, a reference standard designed for the highest level of pressure metrology and research.

The PG9602 piston gauge was developed with the requirements of National Measurement Institutes and researchers in mind. A 100 kg mass load provides a wide range defined by each piston-cylinder assembly and enables improved overlap of piston-cylinders for inter-comparison.

Fluke Calibration AMH automated mass handling technology allows for unattended testing, establishes a better reference vacuum and improves long-term mass stability. The PG9602 piston-gauge, combined with Fluke Calibration’s PG9607 50 mm piston gauge, enables realization and dissemination of pressure values to 10 MPa with low uncertainties, and directly traceable to dimensional measurements.

Solar module

SCHOTT Solar PV, Inc. has announced the 72-cell Schott Power Poly 275 – 285 W module, which is designed to better support commercial and utility projects. The new module offers a 10-year product warranty, 25-year linear power warranty, and positive sorting tolerance to deliver maximum value for large projects.

The modules enable reduction in installation time and cost for large fixed tilt and tracker systems due to their optimal form factor and light weight (43 lbs.).

The Schott Power Poly module is environmentally tested to double the industry certification standards for thermal cycling and damp heat tests to ensure consistent and superior performance throughout the lifetime of the system.
