QPress – QOM-HYDRA 1920 Series
The QOM-HYDRA 1920 Series is a hydraulic-grade pressure transmitter built for demanding fluid-power duty. A micro-fused 17-4PH sensor with all-metal sealing covers 0-16 to 0–1000 bar and withstands an impact life of ten million cycles plus heavy vibration and shock. With 4–20 mA or voltage output, a choice of process threads and an IP65 housing, it holds a dependable ±0.5 % FS reading on hydraulic and pneumatic systems across a wide temperature range. Choose the 1920 over the QOM-HYDRA 1900 when the duty runs beyond 350 bar or demands its ten-million-cycle all-metal sealing.
