Gems 3820 Pressure Switch
Gems® series 3820 pressure transmitters are compact loop-powered (4-20mA) transmitters, with a low power 1-5 VDC option also available. They are the same as the 3800 series with the addition of an integrated 30V/120mA switch. The switch setpoint is specified at time of order for factory setting, yet may also be adjusted using the Gems Calibration Kit. The 3820’s rugged construction makes cost of ownership low and they carry a three-year warranty. They are suitable for hazardous locations and hostile environments and meet applications where dependable, continuous monitoring is preferred.
