Brief introduction:

    Coms-003 series air compressor sensors is combined with digitization , standardization , serialization, large-scale products , reliable and economical solution to customers in bulk or large - scale demand for pressure transmitter , pressure sensor produced in Switzerland , the U.S. produced digital amplifier and the V and I converter chip, thus ensuring the quality of the product.

    Coms-003 series air compressor sensors have the characteristics of very wide anti-jamming capability, able to adapt to the site of a variety of electromagnetic interference , such as high-power electric motor , inverter and other strong sources of interference open will not work properly any impact ;

    Variety of current- voltage type standardized output for the user to select ;
A. 4 ~ 20mA, 12 ± 8mA;
B. 0.5 ~ 4.5V, 0 ~ 5V, 1 ~ 5V;
