Thermocouple/1 wire temperature sensors

Thermocouple/1 wire temperature sensors
Product Detailed
Thermocouple/1 wire temperature sensors 1.All kinds of graduation 2. High stability and accracy

Thermocouple/1 wire temperature sensors

Normally, it isassembled with display instruments, recording instruments, computer, etc. It is direct used to measure site temperature of liquid, vapor, gas and solid surface with output 4-20mA.

Feature

Two-wire output 4-20mA, strong anti-jamming capability;

Save the costs of compensation wire and install temperature transmitter;

Safe, reliable, and long life;

Automatic compensation of cold junction temperature, non-linear correction circuit
