PROFESSIONAL PRESSURE ,LEVEL,TEMPERATURE TRANSMITTER SOLUTION PROVIDER

Instruction:

HPT-33 level transmitter is the full stainless steel construction and full-sealed submersible intelligent level transmitter with high accuracy. It uses high reliable and stable pressure sensor, intelligent processing circuit, precise digital temperature compensation and linearity correction technics for production.

The water-proof cable connects with housing sealed, with vented tube putting in, the submersible level transmitter could be used in the water or liquid in a long time. 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, HPT-33 Intelligent Level Transmitter is widely used for industry field instead of normal 2-wire 4~20mADC analog output transmitter.

Features:

• Ouput signal 4~20mADC, 2-wire
