57025-000

The 57025-000 thermo-magnetic sensor is designed for use in a broad range of applications. Primarily the device is used for controlling temperature and providing an early warning signal to protect equipment from potential damage or malfunction. Depending on the specific requirements, it can be employed to detect hot-spot over-temperature, monitor high and low temperatures, provide an indication of a cool-down or an overload, or detect absent temperatures or other environmental parameters.

The 57025-000 incorporates a precision thermistor and a matched high-durability magnet. Mounted on the rotating shaft of a motor or device, the magnet creates a digital/switching effect for the thermistor that can be set between a minimum and a maximum threshold. When the temperature rises above the established limit, the magnet barrel speed alters the switching pattern and provides the operator with an early warning signal.

The 57025-000 is also suited for use in demanding temperature-controlled sensing applications such as fan speed and temperature monitoring, motor control systems, HVAC systems, and pressure sensing applications. The device features two adjustable sensing thresholds that can be set independently of each other. This flexibility allows for a wide variety of applications and offers significant design freedom.

Apart from controlling temperatures, the device can be used to measure other parameters including pressure and flow. By taking advantage of the adjustable switching thresholds, designers can easily set the hysteresis needed for detecting fluid levels, flow rates, and other dynamic parameters. In addition, the device can be used for non-contact position sensing and presence detection. By matching two magnets to two sensors, the device can be easily installed to provide an accurate and reliable detection signal.

The 57025-000 thermo-magnetic sensor is designed for use in a wide variety of applications and is extremely versatile. The device is easy to install and offers designers significant design freedom. It can be used to detect temperature, pressure, flow rates, and other parameters, and by matching two magnets to two sensors, it offers reliable and accurate detection capability. As such, the device is a great choice for a variety of temperature and environmental sensing applications.
