Overview / Design Principle:
The intrinsically safe 12ET series pressure transducer features stability and toughness via its CVD and ASIC design coupled with a thicker diaphragm. The thicker diaphragm enables these transducer sensors to survive most pressure spikes caused by pump ripple, solenoid valves, etc. The 16ET Series, also intrinsically safe, extends the packaging options by providing an all welded stainless steel back end for demanding industrial applications. A modular design allows special ordering of fittings, electrical cables, etc. for OEM applications. The ASIC and CVD technology enables Gems to offer almost any output over any pressure range.
