Electric contact bimetallic thermometer used in production field of temperature control and alarm automatically. - direct measurement of all kinds of production process Within the scope of 80 ~ 500 ℃, steam and gas medium temperature. Electric contact bimetallic thermometer features: 1 the scene display temperature, intuitive and convenient; 2 with automatic cut off power and alarm functions; 3 safe and reliable, long life; Four kinds of structure forms, can meet different requirements. Working principle of the electric contact bimetallic thermometer is the use of lead contact changes when temperature changes, when contact with the upper and lower limits or disconnected at the same time, make the circuit of relay action, to control and alarm automatically. The main technical parameters & middot; Execution standard: JB/T8803 - 1998 GB3836- 83· Dial nominal diameter: 100 & middot; Precision grade: 1. 0) 1. 5· Thermal response time: & le; 40年代。 Protection grade: IP55 & middot; Normal working atmosphere conditions: temperature - 25 ~ + 55 ℃, relative humidity & le; 85%· Error: set point set point error should not exceed the basic error of 1. 5 times. · Switch: switch difference should not exceed the basic error of 1. 5 times. · Switch repeatability: repeatability limit range is not greater than the absolute value of the basic error limits 1/2. The application of the electric contact bimetallic thermometer to our industrial automation added security, improve the performance of a yard.
