China SAIC 3151HP 3151DR 3151DP 1151HP 1151DR 1151DP Liquid Gas Steam Digital Differential Pressure Transmitter

SAIC differential pressure transmitters are cost-effective instruments designed for measuring the pressure difference between two points in industrial processes. They are widely used in Chinese plants for flow measurement (with orifice plates), level monitoring in closed tanks, and filter differential pressure detection. The transmitters use a piezoresistive or capacitive sensing element and provide a standard 4-20 mA output.
