Temperature Transmitter for Duct Type (2-wire analog output／ digital output) ATT-P4/D4 series

Temperature Transmitter for Duct Type (2-wire analog output／digital output)
Model: ATT-P4/D4 series

Introduction
ATT-P4/D4 series temperature transmitter adopts stainless steel casing and German imported measuring elements, which can monitor temperature signal transmission and convert the measuring element signal into standard current output 4-20mA or digital signal. It is suitable for measuring gas, liquid, steam pressure and all kinds of corrosive media. It is widely used in food, medicine, petroleum, chemical industry, metallurgy, electric power, machinery, etc.

Features
■ OEM service
■ Analog 4~20mA output／digital output are optional
■ Analog 4~20mA output can be non-polar connection, no positive and negative, and has limited current protection
■ Case material: SS304
■ Integrated anti-condensation and heat dissipation structure design
■ High repeatability and good anti-interference ability
■ Small size, easy installation, accurate measurement and long-term stability
■ Stem thermowell and cooling fin are optional
