Integrated overload diaphragm for high reliability
High-precision detection of very low differential pressures
Multivariable sensor with integrated absolute pressure measurement

The transmitter measures the difference between the pressures applied to its high and low pressure sides. The metallic measuring diaphragm deflects with the pressure difference and the electronics convert it into a standardized output signal, with an integrated overload diaphragm for protection.
