Pressure Transducers
QPress – QUP-HP 3300 Series
The QUP-HP 3300 Series is an ultra high-pressure strain-gauge transducer for heavy equipment and hydraulic systems, reading up to 5000 bar at ±0.5 % FS. A robust stainless construction and a 4–20 mA output on M20x1.5 or G1/4 process threads let it drop straight into demanding presses, test rigs and power units. It gives a dependable high-pressure reading on heavy industrial machinery where a standard transducer would reach its working limit. Choose the 3300 for ultra-high-pressure work to 5000 bar; the QUP-HP-OEM 1800 covers volume OEM builds to 600 bar.
