HI-Temp Rugged Bulb & Adjustable Capillary Thermostats

Bulb and capillary thermostats made in China can replace AR/EGO / Rainbow MACHSWON / LDEXIN Series adjustable thermostat switch. The capillary bulb thermostat is a device that uses the liquid flow characteristics of the capillary to control the temperature. Its basic principle is to use the change in the movement state of the liquid in the bulb capillary to control the connection and disconnection of the circuit.

The capillary thermostat consists of a capillary and a temperature-sensing bulb element. One end of the capillary is connected to the controlled temperature device, and the other end is connected to the power supply through an electrical contact. The temperature-sensing element sends different signals according to the high and low controlled temperatures to control the closing and disconnection of the electrical contacts.

When the controlled temperature reaches the predetermined temperature, the liquid in the capillary bulb begins to expand, and through the action of the capillary, the control contact is cut off, the circuit is interrupted, and the temperature rise is controlled. On the contrary, when the controlled temperature decreases, the liquid in the capillary shrinks, the circuit contacts are closed, and the circuit is connected, so that the device heats up. ทางนี้, within a certain range, the controlled temperature will always remain within the predetermined range.

◀caution & notice▶
please keep these instructions in mind before installing a thermostat to your equipment and contact the supplier if you have any questions or doubts. use it within the allowed electric rating for your safety. handle the bulb and capillary with care to prevent damage. do not bend the capillary less than a 5mm radius. do not bend the terminals by force. a damaged bulb can cause failure to achieve the desired temperature. the thermostat body should be installed away from heat sources. higher ambient temperatures can affect its normal function. the sensing bulb should be installed in or close to the heat source. otherwise, it may exceed the allowed tolerance. terminal deformation is not allowed for safety reasons. refund or replacement is not accepted for voluntary repairs or modifications. use the supplied parts with the thermostat. Bulb and Capillary Design; Long-Lasting, Snap-Action Mechanism; Double-Pole, Single-Throw Contacts; 3 Different Bulb Styles Available.

These thermostats use sensitive bulbs that can be used in confined locations. Styles 4 และ 5 bulbs are designed for inserting in drilled holes in platens and dies or for direct immersion.

Sensors for air and pipeline heating applications (style 9) can be coiled to inside radii as small as 13 มม (½inch).
