Product Description

The PM09X series anti-strong corrosion pressure transmitters are specially designed for pressure measurement of strong corrosive media. The product adopts imported ceramic piezoresistive or ceramic capacitive sensors as sensitive elements, and the housing is made of highly corrosion-resistant PTFE or PVDF materials. Combined with a dedicated signal conditioning circuit, it undergoes comprehensive linear error and temperature error compensation to form a pressure and liquid level measurement product with extremely strong corrosion resistance.

Product Application

◆Chemical plants, sewage treatment plants;

◆Various acidic liquids and gases except hydrofluoric acid;

◆High-temperature media.
