Capacitive pressure (liquid level) transmitter-PN52C

Product introduction

PN52C series pressure (level) transmitters use capacitive pressure core working, high and low pressure side of the isolation diaphragm and filling fluid to transfer the process pressure to the filling fluid, and then the filling fluid to transfer the pressure to the sensor center of the sensing diaphragm. The sensing diaphragm is a tensified elastic element whose displacement varies with the pressure applied (for a gauge transducer, atmospheric pressure is applied as on the low pressure side of the sensing diaphragm). The adiabatic pressure transmitter maintains a reference pressure at all times on the low pressure side. The maximum displacement of the sensing diaphragm is 0.1 mm, and the displacement is proportional to the pressure. The capacitive plates on both sides detect the position of the sensing diaphragm. The capacitance difference between the sensing diaphragm and the capacitor plate is converted to the corresponding current or digital HART output signal.
