Pressure Transducers
QPress – QOM-HYDRA 1900 Series
The QOM-HYDRA 1900 Series is a hydraulic-grade pressure transducer for demanding fluid-power systems. A 17-4PH-stainless sensor and a fast 4-7 ms response track pressure on pumps, valves and power units up to 350 bar, and an optional dual output supports redundancy where a single reading is not enough. With an IP67 housing and ±0.5 % FS accuracy, it stands up to the pressure spikes and vibration of mobile and industrial hydraulics while keeping the signal dependable. Choose the 1900 for hydraulic duties to 350 bar; step up to the QOM-HYDRA 1920 for ranges to 1000 bar and ten-million-cycle endurance.
