Principle Of The Adjustable Bulb And Capillary Thermostat
when the temperature of the object to be controlled when the temperature changes in the temperature part of the refrigerant to produce the corresponding thermal expansion and contraction of the physical phenomena (the performance of the volume change) , And the membrane cartridge connected to the temperature sensing portion is expanded or contracted. Through the leverage principle, driving the switch off action to achieve constant temperature purposes. WK series of liquid-type temperature controller with accurate temperature control, stable and reliable, open-stop temperature is small, large temperature control range, overload current and other performance characteristics.function is temperature regulation and control.
Function Of The Adjustable Bulb And Capillary Thermostat
Bulb and Capillary style thermostats use expanding liquid to open
or close contacts in response to temperature changes. No matter
which style or model you choose, all of the capillary thermostats
operate using the same physics. A fluid is encapsulated in a metal
tube (bulb and capillary) and when the temperature changes the
fluid either expands or contracts. This fluid change moves the head
which triggers a snap action switch either opening or closing the
circuit.
The bulb is typically a larger diameter tube mounted in the
material flow being sampled. The capillary is a small tube that
carries the fluid away from the bulb to the head. The head can be a
diaphragm or bellow, which moves with the changing temperatures.
Our capillary thermostats also offer the option of being ambient
compensated to offset the differential in temperature which keeps
our thermostat controls more accurate as it’s environment changes.
Installation and precautions Of The Adjustable Bulb And Capillary Thermostat
1. Users must be based on the characteristics of their products,
the required temperature control, order models and specifications.
2. Thermostat installation, the temperature control as much as
possible the whole close to the controlled surface temperature in
order to achieve accurate temperature control purposes.
3. Installation temperature can not be pressure deformation, so as
not to affect its performance.
4. Do not let the conductive gas or conductive material into the
thermostat or pollute the surface of the thermostat so as not to
affect the electrical insulation properties.
5. Install the bracket M4 screws should not be too long, otherwise
it will damage the thermostat performance.
6. Switch box is a piece of electrical ceramic to gently take to
avoid damage.
7. Bending radius of the capillary can not be less than 5mm
