Original Press Release:
A NEW FAMILY OF LOW DIFFERENTIAL PRESSURE INSTRUMENTS HAS HIGHLY ACCURATE TRANSDUCER
MILFORD, CT - A new family of low differential pressure (DP) instruments from Orange Research features a highly accurate inductive transducer design that delivers long-term stability and low hysteresis. The transducer extends differential pressure measurement capabilities down to 0.04 inches of water.
The transducer uses a beryllium copper diaphragm coupled to an inductive pickup to measure very small changes in pressure. The new instruments cover the pressure range from 0.04 to 800 inches of water. Applications for these sensitive low DP transmitters, calibrators and manometers include HVAC, wafer fabs, pharmaceutical clean rooms, laboratories and hospitals.
A variety of outputs are provided and models are available with integrated LED digital displays, square-root extraction for flow measurement, and pneumatic overload protection. The new family includes a highly accurate portable pressure calibrator to both generate pressure and calibrate sensors. Prices range from $128 to $493 per unit.
