Gamma has long been the measuring principle of choice for high-temperature and high-pressure applications. It works where other measuring principles can’t be used due to build-up, corrosion, abrasion, viscosity or toxicity. But, until now, 2-wire gamma detectors could only be used with an external power supply and required a separately powered transmitter. Endress+Hauser’s new Gammapilot FMG50 is the first 2-wire 4–20mA compact transmitter on the market, which offers considerable cost savings over the entire life cycle of the measuring point.
As well as removing the need for additional installations and wiring for a power supply, the 2-wire concept offers safe and simple maintenance, especially in hazardous areas. The intrinsically safe Ex feature allows safe maintenance work even during ongoing measuring operation. The Gammapilot FMG50 has also been developed according to IEC 61508 for use in SIL2 and SIL3 applications and is currently the safest radiometric device on the market.
Maintenance is quick and easy thanks to electronics that can be swapped in the event of a failure without the need for recommissioning or recalibration. In addition, diagnostic functions and direct feedback on the device are available via the local display, HART or Bluetooth, so the user can see whether the maintenance work was successful without having to return to a separate transmitter. Verification can also be carried out via Heartbeat Technology without interrupting the process.
The new Gammapilot FMG50 is particularly suitable for applications in the oil & gas and chemical industries. Due to its installation outside the vessel, there are no restrictions even with high temperatures and high pressures. In applications with high temperatures, conventional instruments require additional water cooling to ensure trouble-free measurement. Due to its sensor material and unique design, the Gammapilot FMG50 eliminates the need for water cooling, saving planning, installation and operation costs.
