Pressure Transducers
QPress – QOM-CR2 5200 Series
The QOM-CR2 5200 Series is a corrosion-resistant pressure transmitter with a PTFE body and a ceramic sensing element for aggressive and corrosive media. The wetted materials resist chemicals that attack metal diaphragms, and the sensor reads to 20 bar at ±0.5 % FS with 4–20 mA and Modbus RTU outputs. An IP65 housing and a choice of M20x1.5, G1/2, G1/4 or NPT connections suit chemical and metals-processing duty.
