When the temp of the controlled object changes, the working fluid in the temp sensing part of the thermostat will produce corresponding thermal expansion and contraction (the volume change of the working fluid), and the bellows connected with the temp sensing part will expand Or shrink. Through the principle of lever, the switch can be turned on and off to achieve the purpose of constant temp. The WHD series liquid expansion thermostat made by Jaye has the characteristics of accurate temp control, stability and reliability, small temp difference between start and stop, large temperature control adjustment range, and large overload current.
The Capillary Temperature Limiter made by Jaye mainly used in home appliance industry (bath, drum washing machine, heater), electric heating equipment (stainless steel automatic water boiler, electric fryer, griddle, electric oven, food machinery, medical equipment), refrigeration industry (kitchen refrigerator, It is used for temp control such as fresh-keeping cabinets, cold storages, ice machines, fish ponds, cold drink machines, heaters, etc.
The principle of the capillary temp sensor controller is to use the characteristic that the gas or liquid pressure in the temp bulb or capillary changes with temp to drive the control contact action to achieve the control purpose.
The controller requires that the gas or liquid pressure in the temp bulb or capillary changes with the temperature within the temp range that needs to be controlled. In some temp ranges that need to be controlled, refrigerant is a good working medium.
The bending of the capillary should be minimized, even if it is to be bent, the bending radius should not be less than 50mm. The most important thing is that the capillary tube should have protective measures to prevent damage or breakage. The capillary tube can be placed in a groove box or a slotted steel pipe, and the remaining part should be coiled and fixed.
The capillary should be a temp switch or a telemetering thermometer. One end of the capillary tube is connected to a temp bulb, that is, the temp sensing part of the instrument, and the other end of the capillary tube is connected to the display part (for telemetering thermometer) or the execution part (for temp switch) of the instrument. Take a telemetering thermometer as an example to illustrate its working principle: the bulb is filled with medium (liquid or gas), using the principle of thermal expansion of the medium, the pressure generated by the medium expansion is transmitted to the display part of the meter through the capillary tube, and the display of the meter The part is essentially the core of a pressure gauge. According to the pressure generated by the medium at different temperatures, it is sufficient to mark the temp value at the position corresponding to the pointer. So this kind of thermometer is also called pressure thermometer. The surface scale of this kind of thermometer is related to the volume of the bulb and the temp of the medium-volume characteristics.
Jaye makes standard and custom capillary thermostat limiter as per customers' request, you can just specify all the types of thermsotat, the temperature, and the length of the capillary, then we can meet your request.
