Application of bimetallic thermometers for electrical contact points
The electrical contact bimetal thermometer is applied to the production site to automatically control and alarm the temperature. Direct measurement of various production process - 80 ~ 500 ℃ range, steam and gas medium temperature.
Characteristics of electric contact bimetallic thermometers:
1· display temperature, intuitive and convenient;
2· automatic cut-off power and alarm function;
3· safe and reliable, long service life;
4· multiple structure forms can meet different requirements.
The working principle of electrical contact bimetal thermometers
Electrical contact bimetal thermometers are used to drive contact changes with temperature changes. When they contact or disconnect from the upper and lower limits, the relay actions in the circuit can be automatically controlled and alerted.
Main technical parameters of electrical contact bimetal thermometer
1· product execution standard: JB/t8803-1998 gb3836-83
2. Nominal diameter: 100
3· accuracy level: (1.0), 1.5
4· thermal response time: not equal to 40S
5. Protection grade: IP55
6 work normal atmospheric conditions: temperature - 25 ~ + 55 ℃, relative humidity 85% or less
Set point error: the set point error shall not exceed 1.5 times of the basic error limit.
Switch difference: the switching difference should not exceed 1.5 times the basic error limit.
9· switching repeatability: the limit scope of switching is not greater than 1/2 of the absolute value of the basic error.
