Thermometers
Electric contact bimetal thermometer

application
应用于生产现场对温度需自动控制和报警。 Electric contact bimetal thermometer is used in the production site to automatically control and alarm the temperature. Directly measure the temperature of body, steam and gas medium in the range of -80 ~ 500 ℃ in various production processes. zzyfwh.com
Characteristics of electric contact bimetal thermometer
· On-site display temperature, intuitive and convenient;
· With automatic power off and alarm function;
· Safe and reliable, long service life;
· A variety of structural forms can meet different requirements.
working principle
是利用温度变化时带动触点变化,当其与上下限触点或断开的同时,使电路中的继电器动作,从而自动控制及报警。 The electric contact bimetal thermometer uses the change of temperature to drive the change of the contact. When it is disconnected with the upper or lower limit contact, the relay in the circuit is activated, so as to automatically control and alarm.
The main technical parameters
· Product implementation standard: JB / T8803-1998 GB3836-83
· Nominal diameter of dial: 100
· Accuracy grade: (1.0), 1.5
· Thermal response time: ≤40S
· Protection level: IP55
· Normal working atmospheric conditions: temperature -25 ~ + 55 ℃, relative humidity ≤85%
· Setpoint error: The setpoint error should not exceed 1.5 times the basic error limit.
· Switching difference: The switching difference should not exceed 1.5 times the basic error limit.
· Switching repeatability: The limit of switching repeatability is not more than 1/2 of the absolute value of the basic error limit.
