Introduction

A temperature sensor is a device with the purpose of obtaining temperature information from a hot or cold object. There are a variety of types of temperature sensors and they can be used for a variety of applications. One of these is the 66L085-0302, which is a mechanical thermostat. This article will focus on the application and working principle of the 66L085-0302.

Application Field

The 66L085-0302 is used to measure temperatures from 0 to 15°C. Its main application is in HVAC (heating, ventilation and air conditioning) systems. The device is designed to detect and control temperature in order to maintain a comfortable climate in an enclosed space. It is used to regulate when the heating or cooling systems turn on and off based on the temperature.

Working Principle

The 66L085-0302 is a mechanical thermostat, meaning that it utilizes a physical system to detect and control temperature. The device operates by a bimetal sensing element, which is a strip made of two metals with different coefficients of thermal expansion. When the temperature rises or falls the bimetal strip bends, which is converted into an mechanical action – the switch is either opened or closed.The device has two temperature readings – the opening temperature and the closing temperature. The temperature at which the switch opens is adjustable, ranging from 0 to 15°C. The closing temperature is fixed at a temperature 7°C higher than the opening temperature, so that the switch is never in a constant closed or open state.

Conclusion

In conclusion, the 66L085-0302 is a mechanical thermostat used to measure temperatures from 0 to 15°C. It is used mainly for HVAC systems, such as in residential and commercial buildings. The device operates via a bimetal sensing element that is temperature sensitive and its temperature switch is adjustable. With these features, the 66L085-0302 can ensure comfortable climates in enclosed spaces.
