Temperature Sensors - Thermostats - Mechanical

The 2455R04170908 is a mechanical thermostat which functions as a temperature sensor. It was designed to be a high quality, precision, industrial temperature-controlled switch, which can detect and control temperature sensing as needed in any environment. The main mechanism of the sensor is its disk-shaped sensing element, which consists of a bimetallic strip and a copper disc.The bimetallic strip is thermally sensitive and made of two different metals, such as steel and copper, each of which has a different coefficient of thermal expansion. This means that when the temperature changes, the length of the strip changes at a different rate than the diameter of the copper disc, thus causing the disc to rotate. This disc rotation is detected and interpreted as a “switch” by the 2455R04170908’s internal circuitry.At the heart of the 2455R04170908’s signal processing lies a contactless hall effect sensor. This sensor monitors the rotating copper disc and, using a magnetic field, determines if the disc has passed its preset temperature threshold and trips the temperature controlled switch. When the threshold is reached, the switch trips and the 2455R04170908 will send a signal to alert the user of the current temperature condition. This signal can be used to directly cut power or to trigger an alarm, depending on the requirements of the user.The 2455R04170908 is an ideal choice for applications such as controlling air conditioning systems, tracking temperature in cold rooms or refrigerators, regulating temperature in greenhouses and other applications where temperature control is critical. The 2455R04170908’s rugged design makes it ideal for such industrial or commercial environments, and its ability to detect temperatures accurately and quickly ensures that the switch is liable for a wide range of temperature-based applications.The 2455R04170908 is built with a thermally stabilizing envelope which acts as a buffer between the outside environment and the bimetallic strip and copper disc components of the sensor. As such, the 2455R04170908’s temperature measurement accuracy is independent of the external environment, and any unexpected thermal changes or spikes are readily absorbed.The 2455R04170908’s temperature switch setting can be adjusted by a user-defined range, from +20˚C to +90˚C. However, when the temperature reaches the determined threshold the switch will trip, enabling users to customize the temperature range of the sensor depending on their application needs.The 2455R04170908’s small size and low profile make it easy to install in tight spaces, and its solid state design ensures that it can withstand vibrations and impacts without any damage. Furthermore, due to its non-volatile storage, the 2455R04170908 can retain its temperature profile even when the power is turned off, allowing for seamless operation.Given its high accuracy, durability, and user-friendly interface, the 2455R04170908 stands as an ideal choice for monitoring and controlling temperature in industrial and commercial applications. It gives users complete control over their environment, and its ability to accurately sense and respond to temperature changes ensures that any unwanted temperature conditions can be swiftly and correctly addressed.
