Rosemount 2051TG3A Pressure Transmitter Inquiry Item

This Rosemount 2051TG3A is an in-line gauge pressure transmitter of Emerson Rosemount 2051T series. It measures gauge pressure of liquid, gas and steam medium, converts pressure signal into standard 4~20mA DC signal with HART digital communication. It supports local configuration buttons and remote HART parameter adjustment, with 100:1 wide rangeability. The wetted parts adopt 316L stainless steel diaphragm, optional alloy C-276 for corrosive working conditions. It owns SIL2/SIL3 functional safety certification and multiple explosion-proof certificates. Widely used in petrochemical, power plant, water treatment and pipeline pressure monitoring loops.
