QPress – QLS-UNIVERSAL 2200 Series
The QLS-UNIVERSAL 2200 Series is a compact all-stainless general-purpose pressure transducer for everyday industrial measurement. An oil-isolated 316L diaphragm covers ranges from 0-0.35 to 0–600 bar at ±0.5 % FS, and a wide choice of current and voltage outputs plus an M20x1.5 process thread make it straightforward to fit and read. With a fast response under 2 ms, an IP65 housing and proven vibration and shock resistance, it gives a dependable reading on machinery, hydraulics and process plant. Choose the 2200 for general plant duty with current or voltage outputs; the QLS-UNIVERSAL 3200 is the higher-accuracy pick and the 3700 the compact G1/8 option.
