Using sputtered thin-film pressure sensor technology, Gems Sensors & Controls (Gems) Model 3800/3820 Series OEM pressure transmitters and switches target hazardous area and other hostile environments.
Available in seven unique ranges from 0 to 10,000 PSI (0 to 689 bar), the Model 3800 Series has a choice of loop powered (4-20 mA) or low power (1-5 VDC) output. They have a ±0.25% best fit straight line (BFSL) linearity, hysteresis and repeatability specification, with less than 5 millisecond response times. Burst pressures extend from 4x up to 40x FSPR, with 2x or 3x overpressures, depending upon selected range.
While the Model 3800 Series units use NEMA4X IP66 housings with all stainless steel wetted parts and hermetically sealed enclosures without O-rings, the Model 3820 Series is an all stainless steel OEM pressure switch-transmitter. It has a standard 4-20 mA output and optional 1-5VDC output.
