Quick Details

Model Number: HPT-33
Brand Name: Huatian
Place of Origin: China (Mainland)




HPT-33 Submersible transmitter is the full stainless steel construction and full-sealed submersible intelligent level transmitter with high accuracy. It uses highly reliable and stable pressure sensor, intelligent processing circuit, precise digital temperature compensation and linearity correction techniques for production. The top steel cap could protect sensor diaphragm and let liquid media go through unobstructed.

The cable which has vented tube in connects with housing sealed, making sensor connecting to the atmosphere to make sure measurement precise.

Integrated construction and standard output signal could provide easy operation and good automatic control. With 2-wire working, compact size, light weight and easy installation and operation.
