Temperature Sensors - Thermostats - Solid State

The AD22105AR-REEL is a type of temperature sensor-thermostat-solid state. It is widely used in temperature sensing and control applications. It is an integrated temperature sensing device and thermostat that can detect both temperature changes and temperature overshoot events.

The AD22105AR-REEL is composed of a temperature sensing element and a pair of temperature sensing bridges that indicate a temperature threshold. This threshold is known as the trigger threshold. A single switched state is controlled by the integrated temperature sensing device, which consists of two P-N junctions (PNP or NPN configuration) connected in series. When the temperature rises above the trigger threshold, the P-N junction switches to the other state. The second temperature threshold is determined by the two temperature sensing bridges, which opens up a second switch. The respective switched state signals the activation or deactivation of the thermostat.

The AD22105AR-REEL has a range of applications in temperature sensing and control. It is especially useful in applications that require precise temperature control, such as medical instruments and timing devices. It is also used in environmental monitoring and alarm systems to indicate over-temperature events. In addition, the AD22105AR-REEL is used in computers to control the cooling fans and in home appliances to alert users to potential over-temperature warning signs.

The working principle of the AD22105AR-REEL is relatively simple. The device senses the ambient temperature and compares it against the two pre-defined temperature thresholds. If the temperature reaches either of the thresholds, the device opens or closes one or both of the switches to either sound the alarm or activate the cooling system.

To ensure accurate temperature sensing, the device must be calibrated according to the typical operating environment. The device is equipped with a variety of calibration and programming options, which allow users to set the temperature thresholds and adjust the remaining parameters. After calibration, the device performs reliably and accurately in a range of different temperatures.

The AD22105AR-REEL is a reliable and accurate temperature sensor-thermostat-solid state device, designed for use in a variety of temperature control applications. It is highly effective in controlling temperature in computers, medical instruments, and environmental monitoring systems, as well as providing over-temperature warnings in home appliances. The device is straightforward to calibrate, allowing users to set the temperature thresholds accurately and customize their temperature sensing system.
