Submersible Capacitive Transmitters

Series 46 X
Series 46 X Ei

for water level measurements
The Series 46 X combines the ceramic measuring cell for low pressure ranges with the µPelectronics of the digital Series 30 pressure transmitters. The signal values of the pressureand temperature sensors are determined by a polynomial compensation1). The values can be
shown and stored on a PC and can be reprogrammed. A reference tube integrated in the cable
connects the referential chamber of the sensor with the ambient pressure.
