Pressure Transducers
QPress – QDP-DIFF 2800 Series
The QDP 2800 Series is a compact OEM differential-pressure transducer with twin process ports and a millivolt-bridge output. A 316L-stainless body measures differential pressure to 35 bar at ±0.25 % FS, making it suitable for filter monitoring, flow-element and level-by-DP duties on packaged equipment. With dual G1/4 female ports and an ingress-protected housing, it gives instrument builders an accurate, space-efficient DP sensing element to design into their own products.
