QPress – QOM-SMART 2340 Series
The QOM-SMART 2340 Series is an ultra-low-power smart pressure transmitter for battery and remote-telemetry duty. An RS485 digital interface carries both pressure and an on-board temperature readout, with digital compensation and non-linear correction holding ±0.25 % FS across vacuum to 100 MPa. Drawing from a 3.6 V supply and housed to IP65 with stainless and exotic wetted options, it suits utilities, water and chemical monitoring where power budget and digital integration both matter. Choose the 2340 for battery and remote-telemetry points — it runs from a 3.6 V supply; the QOM-SMART 2300 covers powered loops and the 4600 adds a display.
