Product Description

Overview

HPM47W-RPN submersible anti-corrosion pressure transmitter is a fully sealed submersible structure, using an anti-corrosion ceramic piezoresistive pressure sensor. The probe submerged in the medium is made of corrosion-resistant materials such as PP, PVC, PVDF or PTFE, and the gas-conducting cable is made of special anti-corrosion liquid level wire made of PTFE material, which is mainly used for liquid level measurement of corrosive media such as acids and alkalis.
The product has multiple designs of reliable sealing in the connection of the shell, wires and other links, and the internal full potting process is used to ensure that the product has a good service life. It is widely used in many occasions such as chemical industry, environmental protection, medicine, industrial process control, etc.
