Compact differential pressure transmitter | 4 to 20 mA | 0 to 50" w.c.

Series 668B/D Compact Differential Pressure Transmitters

Ranges from 0.1 to 100 in w.c., Overpressure Protection to 15 psig, ±0.8% Accuracy

Our low cost Series 668B/D Compact Differential Pressure Transmitters are capable of sensing differential gage pressure with ±0.8% FS accuracy, and converts this pressure difference to a proportional high level analog output for both unidirectional and bi-directional pressure ranges. These transmitters can withstand up to 15 psig overpressure with no damage to the unit. The compact, lightweight design makes installation simple and easy. Units are protected against incorrect wiring, and include a protective terminal cover.

Calibration Option available under Accessories.
