Product Description

Product Overview:

HPM47W-RPN submerged pressure transmitter is all sealed submerged structure and adopts ceramic piezoresistive pressure sensor. The probe into the measured medium is made of corrosion resistant materials such as PVC, PP,PTFE or PVDF. The gas-guide cable adopts special anti-corrosive liquid level wire, which is mainly used for liquid level measurement of acid, base and other corrosive medium. The product is reliable sealing with multiple designs in the connection of shell, wire and other links. The whole filling and sealing process is adopted inside, which ensures the product has a good service life. It is widely used in chemical industry, environmental protection, medicine, industrial process control and many other occasions.   

Features:

• High-purity ceramic material (96% Al2O3) sensor
• Whole welding process
• Fluorine rubber ring sealing
• Whole potting process, high    molecular sieve, prevent dew
• Built-in weight block in product
