3450G80820969 Datasheet/PDFThermostats are temperature sensors that use mechanical properties to measure temperature. The 3450G80820969 is an example of a mechanical thermostat, and it has several features and applications associated with it. This article will look at the application field and working principle of the 3450G80820969 thermostat.
Application Field
The 3450G80820969 is a temperature sensor used in a variety of applications. It has a range of -20~60℃ with an accuracy of ±2℃. This makes it a great choice for applications that require a wide range of temperature measurements, such as automotive and HVAC (heating, ventilation, and air conditioning) systems. In addition, the thermostat has an alarm output, which allows it to send an alert when the temperature gets too high or too low.
The 3450G80820969 is also popular in the medical field, where it is used in patient monitoring systems and blood analysis systems to measure body temperature. Additionally, it is often used in temperature-controlled manufacturing and storage processes, such as in clean rooms and freezers. Finally, it is used in scientific research to measure the temperature of various experiments.
Working Principle
The working principle of the 3450G80820969 is based on two main components: a mechanical temperature sensor and an electronic control circuit. The mechanical temperature sensor is made up of two metal strips that are separated by an insulating layer. When the temperature changes, the strips expand or contract at different rates. This causes the resistance between the two strips to vary, which in turn changes the voltage output of the sensor.
The voltage output is used by the control circuit to determine the temperature. The circuit amplifies the voltage signal from the sensor and then compares it to a set point. If the measured temperature is higher or lower than the set point, the circuit sends a signal to an alarm or other device. If the temperature is within the set range, the circuit does nothing.
In summary, the 3450G80820969 is a mechanical thermostat with a wide range of applications. It is used in automotive, HVAC, medical, manufacturing, and scientific fields. It works by employing a mechanical temperature sensor combined with an electronic control circuit. This allows it to accurately measure temperature and respond to changes in temperature.
