Product Description
HPM47W 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 sewage, seawater and other media and all high-demand liquid level measurement.
