Temperature Sensors – Thermostats – Mechanical

A 3450RC 81740185 application field and working principle can be found in a variety of scenarios. Most notably, these devices are used when accurate temperature control is essential. In different industries, such as aviation and automotive, temperature-sensitive components must be kept within a certain optimum range.

The 3450RC 81740185 is a mechanical thermostat that works through a thermally sensitive switching element. This part is usually a bi-metallic strip, which is made up of two different metal layers that are joined together. As the temperature rises, the different properties of the layers cause the strip to bend out of shape. This distortion is used to contact a switch contact, in order to open or close a circuit when the temperature reaches its threshold.

The bi-metallic strip works at an adjustable temperature range, which is selected by a thermostat calibration knob. This way, when the temperature reaches the threshold, the bi-metallic strip bends into a curved shape and separates the two contact points. This mid-point breaks the circuit and prevents the flow of electricity as long as the bimetallic strip is in a curved shape. As soon as the temperature falls, the strip returns to its original straight shape, thereby closing the circuit and allowing electricity to flow again.

The range of temperature can be varied between 0°C-40°C, 0°F-100°F, and -20°C-120°C, depending on the particular model. Temperature ratios can be adjusted within the range from 2°F-8°F (1°C-4°C).

The most common application for the 3450RC 81740185 is temperature control of motor vehicles such as airplanes, cars, and trucks. However, there are many other potential uses, such as medical device temperature control or air conditioning and heating systems.

The main advantages of a mechanical thermostat are that it is simple to install, more reliable and highly cost-effective. Furthermore, by designing custom parts for the bi-metallic strip, it is possible to optimize the temperature range and level of precision for each application.

In conclusion, the 3450RC 81740185 mechanical thermostat is a reliable and affordable temperature control solution for multiple industries. It is a simple and effective way to maintain accuracy and safety in the operation of many different products.
