Senasys manufacturers a large variety of temperature switches for HVAC systems:
- Bi-metal temperature switches
- Bulb and capillary thermostats
- Mechanical line voltage thermostats
Temperature switches found in HVAC systems are typically mechanical controls that are based on physics. More times than none, most HVAC systems have a requirement for these controls rather than an electronic type controller because failure modes are limited versus an electronic control. Rather than an electronic controller using inputs/outputs to communicate with the HVAC equipment, our temperature switches react to change in the environment causing the equipment mode to change as a reaction.

Temperature Sensing Switches
Senasys manufactures a wide array of temperature switches for HVAC systems including bi-metal snap disc and duct limit temperature switches, bulb and capillary thermostats. The temperature switches for HVAC systems typically are used as a fan or limit when a pre-defined temperature is reached.
BI-METAL SNAP DISC TEMPERATURE SWITCHES
Quality-engineered thermal sensors specifically designed for a variety of major HVAC appliances, including room unit and space heaters, air conditioning systems and wood stoves. Commonly used as a limit, when temperature within the system exceeds the defined set point, the contacts open to shut the appliance off.

BI-METAL DUCT LIMIT SWITCHES
Our bi-metal duct limit switches are used to shut down HVAC equipment as well. Mounted to the outside of an air duct, the switch senses an increase of temperature within the duct system shutting down the equipment to avoid the possible travel of fire, smoke, or other harmful environments.

BULB AND CAPILLARY THERMOSTATS
Our bulb and capillary thermostat line are found to be used as limit or control in HVAC equipment. Similar to our bi-metal temperature switches, the bulb and capillary style uses a liquid filled sensing element which expands/contracts when temperature changes opening or closing the micro switch contacts.

LINE VOLTAGE THERMOSTATS
The line voltage thermostats function like a bulb and capillary style thermostat, but are commonly used among end users to control industrial heaters, barn fans and other HVAC equipment. When temperature within the system changes, the thermostat will either turn on an industrial heater, a fan, or shut a system down. Visit our website to learn more!
