Pressure Transducers
QPress – QLS-STAINLESS 2200 Series
The QLS-STAINLESS 2200 Series is a rugged all-stainless pressure transducer for wide-range industrial measurement. A 316L diaphragm in a 304-stainless body reads compound vacuum through 1000 bar at ±0.5 % FS, with a choice of current and voltage outputs and a broad range of process threads. An IP65 housing, strong EMC performance and proven vibration and shock resistance keep readings stable on hydraulics, machinery and process equipment across a wide temperature span.
