Pressure Transducers
QPress – QLS-SURGE 2200 Series
The QLS-SURGE 2200 Series is a robust stainless-steel pressure transducer built for hydraulic systems where pressure surges and spikes are routine. A fast response and high surge tolerance keep readings stable on pumps, valves and actuators, and the sensor reads to 600 bar at ±0.5 % FS with a 4–20 mA output. A wide choice of process threads, including G1/2, G1/4, M14x1.5 and NPT, suits general industrial and aerospace duty.
