New approvals for GE pressure sensors

The latest pressure sensing platform from the Sensing business of GE Measurement & Control Solutions now carries FM and FMc Approvals in addition to its existing IECEx/ATEX Intrinsically safe certifications. As a result, these pressure sensors can now be used worldwide in hazardous zone applications in the oil and gas and process industries, as well as in mining.

The sensor is called the UNIK 5000, and comes from the Groby factory near Leicester that was famous for Druck pressure sensors and transmitters. I suppose that might have been an alternative name that GE considered before adopting the UNIK 5000 styling.

With its flexibility, versatility, accuracy and reliability, the UNIK 5000 platform is said to have already made a significant impact throughout the industrial, aerospace, power generation and instrumentation sectors, as a pressure measurement range, that is available at short lead times to satisfy the majority of user requirements.

As Ian Abbott, product manager for the range, explains, “We have already made significant inroads into the oil and gas sector with our existing intrinsic safety certifications. The achievement of FM Approvals means that we can now satisfy hazardous zone requirements on a global scale.”

By combining silicon technology and analogue circuitry with modular design and lean manufacturing techniques, the new platform offers custom-built pressure sensors from standard components, matching accuracy and specification to meet individual requirements.

The high quality, piezo-resistive sensors in the platform offer high levels of performance without the use of digital electronics, so that the sensors are suitable for sensitive applications such as those requiring low power, pulse power, and fast response. They are available in a range of pressures from 70 mbar (1psi) to 700 bar (10,000psi) and in three grades of performance: industrial, improved and premium. These offer a range of accuracies from ±0.04% FS to ±0.2% FS. A choice of pressure connectors is available and electrical connectors may be selected to suit most environments with operating temperature ranges from–55 to +125°C. A suite of eight electronics boards allows outputs suitable for most applications and a further configurable option is to allow individual specification of voltage output. All the 5000 sensors feature low noise and high over-pressure capability and are constructed from stainless steel.
