1. Product Overview
YGM227 is a high-precision micro differential pressure transmitter with piezoresistive membrane MEMS pressure sensor chip integrated inside, which not only provides better stability and linearity, but also takes into account the requirements of pharmaceutical factories and clean workshops for on-site LCD display of micro differential pressure transmitter. The internal circuit of the transmitter is highly integrated, providing three output modes of 4~20mA, 0~10V and RS485.
