Temperature Sensing Devices - Mechanical

Temperature sensing devices come in a variety of forms with a range of capabilities and levels of accuracy. Mechanical temperature sensors, such as the 66L080-0251, are basic yet reliable and cost-effective solutions for measuring and controlling temperatures in a range of applications, such as refrigeration and heating systems. This article looks at the 66L080-0251 application field and working principle.

Application Field

The 66L080-0251 is a mechanical temperature sensing device designed to measure temperatures from -20°C to +110°C (-4°F to +230°F). This range of temperatures is suitable for many applications, including refrigeration, air conditioning, and heating systems. Furthermore, due to its cost-effectiveness, it is also a popular choice for commercial kitchens.

The 66L080-0251 offers excellent temperature stability, which makes it ideal for applications where precise temperature control is paramount, such as fermentation, pharmaceutical production, and laboratories. The device is also suited to high-altitude and outdoor applications due to its IP65 rating.

Working Principle

The 66L080-0251 is a mechanical temperature sensor which operates using a bimetallic strip. A bimetallic strip is made by combining two strips of metal with different linear coefficient of thermal expansion. This allows the strip to curl or curve proportionally to the temperature.

The 66L080-0251 utilizes two strips of metal which are connected to two electrical contacts, forming a simple electrical switch. As the temperature of the environment changes, the bimetallic strip either contracts or expands. This movement of the strips then closes or opens the electrical contacts, depending on the temperature. This completes the circuit and either sends a signal to switch on a heating or cooling system, or an alarm if an unsafe temperature range is hit.

The 66L080-0251 is a reliable and cost-effective solution for controlling temperatures in a variety of commercial, laboratory, and industrial environments. It is a versatile temperature sensing device with a wide range of applications and an excellent temperature stability.
