Short Description:

Product Detail

Product Tags


★ Accurate temperature control;
★ Great contact capacity;
★ Wide control range;
★ High reliability.

Application: Temperature control for the heating electrical appliances such as electric water heater,fryer,cylinder washing machine,electric water boiler,sealing machine,electronic oven,baking pan,subterrene,and electric griddle etc.

Working principle

The special industrial oil inside the capillary and bulb probe. When the temperature rises, must be quickly detected by the sensor bulb, then the oil begins to expansion to make contactor acts.

What do thermocouples do?

Vcrown offers the different Series of adjustable bulb and capillary thermostats suitable for applications requiring variable temperature setting ability and remote control. Vcrown Series design incorporates a changeover thermal switch and an auxiliary switch useful for fan control or alarm signal. A variety of available features, a large in-stock inventory, and a surprisingly low price combine to make the Vcrown Series bulb and capillary thermostat an excellent value.

How does a capillary tube thermostat work?

Bulb and capillary thermostats have a fluid filled bulb and respond quickly to change in temperature. When temperature rises the bulb fluid expands via the capillary tube to an expandable diaphragm or bellows to open or close the contacts.

Items to be noted

★ Client shall make an order according to the characters of his product, and the range of temperature that needs to be controlled.
★ Do not make conductive gases or conductive matters enter into the temperature controller or stain its surface, to prevent its electric insulation from being influenced. 5. Do not use over-length M4 wire for bracket fixing, otherwise temperature controller performance will be destroyed.
★ Switch box is a ceramic item, and therefore shall be handled carefully.
★ In temperature controller fixing, keep temperature-sensing duct closely contact the surface where temperature needs to be controlled, to well fulfill its function.
★ Do not press the temperature-sensing duct to be deformed in fixing to avoid influencing its performance.
★ The bending radius of capillary shall not be less than 5mm.

What is bulb and capillary sensor?

Bulb and Capillary style thermostats use expanding liquid to open or close contacts in response to temperature changes. Simple to use with a calibrated knob for setting the temperature and the ability to directly switch load current for one of two poles directly.

Elements & Purpose

Usage: It's mainly used for the temperature control of household electrical appliances (showers, rolling-type washers, fan heaters), electrothermal equipment (stainless steel full automatic water boilers, electrothermal fryers, baking stoves, electronic ovens, foodstuff machinery, medical equipment), and refrigeration industry (kitchen cooling cabinets, preservation cabinets, refrigerators, ice-makers, rearing ponds, cold-drinks makers, heating machines) etc.

Elements: The volume of the material in the temperature sensing part of temperature controller will inflate or deflate when the temperature of the controlled object varies, which causes the film box that is connected to the temperature sensing part inflating or deflating, then drives the switch on or off through a leverage function to keep a constant temperature. AGO Series Liquid Inflated Temperature Controller is characterized by accurate temperature control, reliable, small on/off temperatures difference, a wide range of temperature control and large over loaded current etc.
