    The pressure transmitter consists of two high accuracy piezoresistive sensors with stainless steel isolation diaphragms. Both sensors measure static pressure and the difference between these two measurements is computed electronically. The use of high accuracy and stable sensors makes this measurement possible. Since each sensor measures the full static pressure, there is no possibility of overpressurizing the transmitter if one sensor is disconnected from the line. No complex and expensive balancing valves are needed.
