The 20300 Series low differential pressure (DP) transmitters measures differential pressure in the range of 1.0 to 400 in. of water. The transmitters have an inductive transducer designed to deliver long-term stability and low hysteresis. A beryllium copper diaphragm coupled with an inductive pickup is used to measure very small changes in pressure, according to the company. Fully featured models have integrated LED digital displays, square root extraction for flow measurement, pneumatic overload protection, and various outputs.
