Immersion Thermostat Afriso TC2 0–90°C, capillary sensor, model 6742100

The Afriso Immersion Thermostat TC2 with capillary sensor and a 0–90°C measurement range is a compact mechanical temperature control device intended for direct mounting in liquids, boilers, tanks and similar process vessels. The thermostat provides switching of electrical circuits based on a user-set temperature setpoint, using a capillary sensor that transmits temperature to the control element. The design emphasizes straightforward installation and dependable, repeatable switching behaviour in heating and process applications that require a mechanical control solution.

Advantages

This immersion thermostat offers a simple mechanical control principle that does not require auxiliary power for sensing and switching, ensuring operation in installations with limited electrical complexity. The capillary sensor allows flexible placement of the sensing bulb at a distance from the control head, enabling installation in tight or thermally representative positions inside liquids or tanks. The robust construction is suitable for common heating environments and provides clear, direct switching action at the selected temperature.

Suitable for

• Temperature control in boilers and hot water tanks
• Level-controlled heating circuits and storage vessels
• Industrial process vessels with liquid media
• Systems where compact immersion sensors and mechanical switching are preferred

Key specifications

• Temperature range: 0–90°C
• Sensing element: capillary sensor with immersion bulb
• Control type: mechanical thermostat with adjustable setpoint
• Mounting: immersion into liquid/tank via sensor bulb and fixed control head
• Typical applications: boilers, tanks, process vessels with liquid media

How to use

Mount the sensor bulb into the liquid or vessel at the point where representative temperature measurement is required and secure the control head in the designated position. Set the desired switching temperature using the adjustable setpoint on the thermostat head. Connect the switching contacts to the controlled circuit following the electrical wiring instructions supplied by the system integrator or installer. Verify correct operation by observing switching behaviour when the liquid temperature crosses the setpoint and adjust the setpoint if necessary for precise control.

Usage recommendations

For reliable performance, ensure the sensor bulb is fully immersed and thermally coupled to the medium being measured. Avoid mounting the bulb near inlet streams or heat sources that may cause unrepresentative local temperatures. Regularly inspect the mechanical connections and wiring for wear or corrosion in heating environments and follow local electrical and safety regulations during installation and maintenance.
