67L040P

Introduction

The 67L040P is an electro-mechanical temperature sensing thermostat produced by Mirion Technologies. It is designed to be used in a variety of applications where a precise, reliable temperature sensing thermostat is required. This paper will discuss the application field of the 67L040P and its working principle.

Application Field

The 67L040P is a versatile thermostat suitable for a wide range of applications in many industries. In particular, it excels at controlling temperature in automated machinery and process control systems. It can be used to shut off electricity or gas when a certain temperature is reached, enabling a safe and efficient running environment. It is also ideal for use in HVAC systems, where temperature control is pivotal to the comfort of occupants. Additionally, the 67L040P can serve as an over-temperature protection switch in many types of equipment.

Working Principle

The 67L040P works by comparing the sensed temperature to the set-point temperature. It uses a bimetallic sensing element to detect temperature changes. This element consists of two pieces of metal that expand and contract at different rates with temperature change. The expansion or contraction of the bimetallic element moves the contact of the electro-mechanical switch and completes or breaks the switch circuit. This switches the external power on or off, depending on the setpoints.

Once the set point temperatures are set, the thermostat switches power on or off, as needed. It has a temperature range of -20°C to 200°C, and a maximum current rating of 10A. It is capable of creating a differential as narrow as 0.5 °C, making it suitable for applications requiring precise temperature control. Additionally, the design is relatively small, making it suitable for integration into compact systems.

Conclusion

The 67L040P is an electro-mechanical temperature sensing thermostat suitable for a variety of applications. It is particularly useful for controlling temperature in automated machinery and process control systems, as well as HVAC systems. The thermostat works by using a bimetallic sensing element to detect temperature changes and prompting the electro-mechanical switch to complete or break a power circuit. It is capable of controlling temperatures within a differential as narrow as 0.5°C, making it an excellent choice for applications requiring precise temperature control.
