Some of the 3800 features include availability in seven unique ranges from 0 to 10,000 PSI (0 to 689 bar), with choice of loop powered (4-20 mA) or low power (1-5 VDC) output. They feature NEMA4X IP66 housings, all stainless steel wetted parts and hermetically sealed enclosures without O-rings. Dual seal approval and flush mounting are optional.
The new Model 3820 Series is an all stainless steel OEM pressure switch-transmitter. Featuring a standard 4-20 mA output as well as an optional 1-5VDC output, it builds upon the many performance attributes of the Model 3800, with the addition of a 30V, 120 mA normally open solid state relay switch with ±2% URL accuracy. Both the pressure switch set points and pressure measuring range are also field adjustable via the optional calibration kit. All Model 3800 and 3820 Series units are FM, ATEX and CE approved and are accompanied by a three-year product line warranty.
