Pressure Transducers
QPress – QLS-UNIVERSAL 3200 Series
Where measurement needs to be accurate as well as general-purpose, the QLS-UNIVERSAL 3200 Series delivers ±0.25 % FS across gauge and absolute ranges from 0–0.025 bar up to 0–250 bar. A 316L-stainless wetted section and IP-rated housing suit water systems, test rigs and process plant, while the 4–20 mA output and G1/4A connection make it straightforward to fit and read. One accurate model therefore covers low-pressure and mid-pressure duties without changing supplier or wiring approach. Choose the 3200 when ±0.25 % FS accuracy or absolute ranges matter; the QLS-UNIVERSAL 2200 and 3700 cover general and compact duties.
