Pressure Transducers
QPress – QOM-SMART 4600 Series
The QOM-SMART 4600 Series is a smart pressure transmitter with an on-board LCD and RS485, so an engineer can read and configure it at the point of installation. It covers vacuum to 1000 bar at ±0.25 % FS and offers both 4–20 mA and Modbus RTU, letting one model serve analogue loops and digital networks alike. A 316L wetted section and IP-rated housing suit process and utility duty where local readout and digital integration both matter. Choose the 4600 when engineers need to read and configure at the instrument; the QOM-SMART 2300 and 2340 cover loop and telemetry duty without the display.
