Description

50-500 degree thermostat high temperature mechanical thermostat
Pressure type temperature control-principle performance and use:
Principle and performance: When the temperature of the controlled object changes, the working medium in the temperature-sensing part of the thermostat will generate the corresponding physical phenomenon of thermal expansion and contraction (volume change of the working medium), and the capsule connected with the temperature-sensing part will produce Swell or shrink. Through the lever principle, the on-off action of the switch is achieved to achieve the purpose of constant temperature. The liquid expansion thermostat has the performance characteristics of accurate temperature control, stable and reliable, small temperature difference between start and stop, large temperature adjustment range, and large overload current.
Uses: Mainly used in home appliance industry (shower, drum washing machine, heater), electric heating equipment (stainless steel automatic water heater, electric fryer, food machinery, medical equipment), refrigeration industry (kitchen refrigerator, fresh-keeping cabinet, cold storage) , Ice maker, fish pond, cold drink machine, heater) and other temperature control.

2. Cut-off temperature: According to user requirements, the temperature design range (50 ℃ ～ + 500 ℃)
3. Product life:> 100,000 times
4. Electrical strength: AC2000V / 1min
5. Normal insulation resistance: ≥100MΩ
6. Contact resistance: ≤50mΩ
7. Moisture insulation resistance: ≥10MΩ
8. Temperature response rate: ≤1.0 ℃ / min
9. Small current: 200mA
Normally closed and normally open introduction:
Normally closed—You set a certain temperature value. Below this temperature value, the switch is closed (on). When the temperature exceeds this value, the switch automatically switches to the off state.
Normally open-you set a certain temperature value, the switch is open below this temperature value, the switch automatically switches to the closed (on) state beyond this temperature value. The opposite of normally closed.
Wiring method:
The two-pin thermostat has two lugs, which are 1 and C respectively. When 1 and C are connected in series on the power circuit, when the temperature rises to the required control temperature, it will automatically cut off the power (the electrical appliance stops working), and when the temperature decreases, it will automatically turn on the power (the electrical appliance starts working).
The three-pin thermostat has three lugs, which are 1, 2, and C pins. When 1 and C are connected in series on the circuit, the same reason applies. When 2 and C are connected in series on the circuit, when the temperature rises to the required control temperature, it will automatically turn on the power (the electrical appliance starts to work), and when the temperature decreases, it will automatically cut off the power (the electrical appliance stops working)
Precautions:
1. The user must propose the order model and specifications according to the characteristics of the product and the temperature to be controlled.
2. When the thermostat is installed, the entire temperature sensing tube should be as close to the temperature controlled surface as possible to achieve the purpose of accurate temperature control.
3. Do not deform the temperature sensing tube during installation to avoid affecting its performance.
4. Do not allow conductive gas or conductive substance to enter the thermostat or pollute the surface of the thermostat to avoid affecting the electrical insulation performance.
5. The M4 wire of the mounting bracket should not be too long, otherwise it will damage the performance of the thermostat.
6. The switch box is a ceramic part of an electrical appliance. Handle it gently to avoid breakage.
7.Capillary bend radius cannot be less than 5mm.
