Hot Capillary Thermostat

A hot capillary thermostat is a device that uses the characteristics of the liquid or gas in a capillary tube to expand or contract with changes in temperature to control temperature. The following is its detailed introduction:

1. Basic principles

The working principle of a hot capillary thermostat is based on the effect of thermal expansion of a capillary liquid or gas. When the controlled temperature reaches a predetermined value, the liquid or gas inside the capillary tube will expand, pushing the connected contacts or mechanisms to act, thus controlling the on and off of the circuit, first controlling the operation of the heating or refrigeration equipment to maintain the controlled temperature at within the predetermined range. On the contrary, when the controlled temperature falls below a predetermined value, the liquid or gas in the capillary tube shrinks and the button or mechanism is reset, allowing the heating or cooling equipment to continue operating.

2. Structural composition

Hot capillary thermostats usually consist of capillary tubes, temperature sensing elements, electrical contacts and necessary fixing and connecting parts. Among them, the capillary tube is a key component, and its length, inner diameter, material and other characteristics will affect the control accuracy and speed response of the thermostat. The temperature sensing element is used to sense changes in temperature and convert the temperature signal into a controllable electrical signal. The electrical contacts control the on and off of the circuit based on the signal from the temperature sensing element.

3. Technical characteristics

Precise temperature control: The hot capillary thermostat has high temperature control accuracy and can meet the temperature stability requirements of many precision instruments and equipment.

Simple structure: Its structure is relatively simple, the manufacturing cost is low, and it is easy to install and maintain.

Good stability: Since the expansion or contraction of liquid or gas in the capillary tube with temperature changes is relatively stable, the hot capillary thermostat has good stability.

Strong adaptability: The hot capillary thermostat is suitable for a variety of temperature control situations, including high temperature, low temperature and normal temperature environments.

4. Application areas

Hot capillary thermostats are widely used in areas requiring precise temperature control, including but not limited to:

Food processing industry: used to control the temperature of ovens, fryers and other equipment to ensure food cooking quality.

Pharmaceutical industry: Control the reaction temperature during the pharmaceutical process to ensure drug quality.

Chemical industry: Control the temperature during chemical reactions to ensure smooth progress of the reaction.

Electronics industry: Control temperature to ensure product quality in precision processes such as semiconductor manufacturing.

5. Purchase suggestions

When purchasing a hot capillary thermostat, it is recommended to consider the following factors:

Temperature range: Make sure the temperature range of the selected product meets actual needs.

Accuracy requirements: Choose the appropriate model according to the temperature control accuracy requirements of the application scenario.

Brand and quality: Choose well-known brands and high-quality products to ensure product stability and reliability.

After-sales service: Understand the supplier's after-sales service policy and service quality in order to obtain timely technical support during use.

To sum up, the Hot Capillary Thermostat is a device that uses the capillary thermal expansion effect to control temperature. It has the characteristics of precise temperature control, simple structure, good stability and strong adaptability, and has been widely used in many fields. When purchasing, it is recommended to consider factors such as temperature range, accuracy requirements, brand quality and service.
