Product Description
HPM47W (with ceramic capacitive sensor) anti corrosion pressure transmitter is a fully sealed submersible structure and uses an anti corrosion ceramic capacitive pressure sensor. The probe put into the measured medium is made of 316L, titanium alloy or
corrosion resistant materials such as PVDF, PP, PTFE or PVC, and the gas conductive cable is made of with PTFE or polyurethane jacket . It is mainly used for liquid level measurement of corrosive media such as acids and alkalis or s ewage, seawater and other media and all high demand liquid level measurement.
* The size is the distance between the induction diaphragm and the bottom
1.Used for fixing and supporting the whole product on the top
2. Besides G1 thread, other threads can be customized if needed
Used to secure and support the entire product on top
Measurement results need to consider the influence of the height of the bottom weight on the height from the sensing diaphragm to the bottom of the measurement medium.
