In industrial temperature regulation, bulb and capillary thermostats play a crucial role in controlling heating elements with precision. We specialize in manufacturing these thermostat units, which consist of three key components: the sensing bulb, the capillary, and the microswitch. These units integrate into temperature controllers to ensure accurate thermal management in various industrial systems.
Our thermostat units have earned a reputation for durability and precision engineering. Designed to meet the demanding needs of industrial environments, they provide long-term reliability and consistent performance. If you’re looking for high-performance components to enhance your temperature control systems, we offer custom configurations to meet your specific requirements.

The Functionality of Bulb and Capillary Thermostats
Bulb and capillary thermostats operate by detecting changes in temperature through the sensing bulb, which is immersed in the medium being monitored. The capillary transmits this thermal data to the microswitch, which then activates or deactivates the heating element. The thermostat’s precise performance directly impacts the reliability of the temperature controller it’s used in.
The Bulb: Acts as the primary temperature sensor, immersed in the target environment. It responds to thermal changes, causing pressure fluctuations in the system.
The Capillary: Transfers pressure changes from the bulb to the microswitch, ensuring the control mechanism receives accurate data.
The Microswitch: Reacts to pressure transmitted by the capillary, controlling the operation of the heating element. It either maintains an adjustable temperature or functions as a high-limit control, shutting down the system when maximum temperatures are exceeded.
Importance of Our Bulb and Capillary Thermostat Units in Temperature Controllers
At Stemco, we supply complete bulb and capillary thermostat units to manufacturers, helping them produce high-performance temperature controllers for a wide range of industrial applications. Our thermostats offer several critical advantages:
Accurate Temperature Control: The combination of a high-quality sensing bulb, responsive capillary, and reliable microswitch allows for smooth on-off cycling of heaters, preventing temperature overshoot or undershoot.
High-Limit Safety: Many industries rely on our thermostats to protect equipment. The microswitch ensures that power to the system is cut once temperatures reach the pre-set limit, preventing overheating and damage.
Durable Construction: Built to endure extreme conditions, our thermostats function reliably under high temperatures, pressure, and harsh environments.
