Introduction
MDM492 differential pressure transmitter is used to measuring
lower pressure range. It uses high performance sensor and amplifier
circuit outputing 4~20mA current signal. The whole product is stable and reliable, can be used
for lower pressure measure of boiler, vintage, engine and so on.
