Application 
 Bimetal thermometers used in electrical contacts on the production site to be automatic temperature control and alarm. Direct measurement of the production process of -80 ~ 500 ℃ range of body temperature steam and gases. 
 Feature 
 * Live show temperature, easy and intuitive; 
 * Automatic power off and alarm functions; 
 ? Safe, reliable, long life; 
 * A variety of structural forms, which can meet different requirements. 
 Work 
 Electric Contact Bimetal thermometer is driven by contact when a change of temperature change, when its contact with the upper and lower limits or disconnected while the circuit in the relay to automatically control and alarm. 
 Main technical parameters 
 * Product performance standards: JB/T8803-1998 GB3836-83 
 * Dial Nominal Diameter: 100 
 ? Accuracy rating: (1.0), 1.5 
 ? Thermal response time: ≤ 40S 
 * Protection class: IP55 
 * Work properly atmospheric conditions: temperature -25 ~ +55 ℃, relative humidity ≤ 85% 
 ? Set-point error: Set point error should not exceed 1.5 times the basic error limit. 
 ? Switching difference: switching difference should not exceed 1.5 times the basic error limit. 
 ? Switching Repeatability: Repeatability limit switch range is not greater than the absolute basic error limit of 1 / 2.
