Introduction to 66L080-0226

The 66L080-0226 is a temperature sensing element with an operating range of -40°C through +100°C. It is a thermal thermostat with a mechanical device incorporated into it which can be used for initiating or signaling a desired action when the temperature reaches a certain point. It is designed to provide a low cost solution for temperature sensing applications where a single on/off switch is needed.

Application Field of 66L080-0226

The 66L080-0226 is ideal for applications where temperature sensing is needed, for example, in air conditioning, refrigeration, automotive and marine applications. It can be used in temperature-dependent processes, such as in the maintenance of product temperatures, as well as for temperature monitoring in storage and transport of perishable goods such as food and medication.The 66L080-0226 has a wide range of uses and can be employed wherever a single on/off switch at a set temperature limits is desired. Reliable and accurate temperature control can be achieved with this product, and is used in applications such as heating and cooling systems, HVAC systems, room temperature regulating, and other temperature control systems.

Working Principle of 66L080-0226

The 66L080-0226 works on a simple principle of using a bimetallic disc which is sensitive to temperature changes to activate or deactivate a switch. The bimetallic disc is composed of two metals, which expand at different rates when heated and contract at different rates when cooled. This means that when the temperature of the bimetallic disc changes, its shape also changes, activating the switch when the temperature limit is reached.When the temperature of the sensor reaches the set temperature limit, the bimetallic disc expands, increasing tension on a toggle lever connected to the switch. This moves the switch off, triggering an action which can be a system shutdown, alarm activation, or other related event. Once the temperature drops below the limit, the bimetallic disc contracts, upsetting the balance of the toggle lever and releasing tension on the switch, which then turns the whole system back on.

Conclusion

The 66L080-0226 is a temperature sensing device with an operating range of -40°C to +100°C. It is designed to provide a low cost solution for temperature sensing applications where a single on/off switch is needed. It is a thermal thermostat which uses a bimetallic disc to activate or deactivate a switch, depending on the temperature, and can be used in temperature-dependent processes such as in the maintenance of product temperatures, as well as for temperature monitoring in storage and transport of perishable goods.
