armored thermocouple has many advantages such as bendable, hi-pressure resistant, quick response, firm and durable, etc. it is used as the sensor measuring temperature just like industry-use assembly type thermocouple. it is usually connected with display meter, recording meter and electronic regulator, etc. and meanwhile can be regarded as thermal element of assembly type thermocouple to directly measure temperature of liquid, vapor, gas and solid surface ranging from 0�� to 1300�� during various production process.
