Pressure Transmitter- Series 634E
4-20 mA signal. Two wire operation. Ranges to 6000 psi.
Series 634E Transmitters sense a single pressure of air, compatible gas or liquid and produce a standard 4-20 mA output signal Sensitive silicon strain gage measures within ±2% F.S.O. Convenient 2-wire operation simplifies installation and expands application versatility over comparable 3 or 4-wire units. Zero and span adjustments are fully protected inside a rugged die cast aluminum housing with durable gray polyurethane finish. Enclosure is designed to meet NEMA 4X requirements.
