Temperature Sensors - Thermostats - Solid State

The LM57BISD-10/NOPB is a solid-state temperature sensor used to measure the temperature of surfaces. It works by sensing the temperature of the surface it is attached to, and then sending a signal to indicate the temperature to the electronic control unit (ECU).

This temperature sensor is designed to be used in a wide variety of applications such as HVAC systems, HVAC control systems, industrial and medical equipment control, ovens, and reflow ovens. It is a compact, low-cost, versatile, and field-proven solution for applications where accuracy and reliability are paramount.

The LM57BISD-10/NOPB utilizes a proprietary thermistor-based sensing element for accurate temperature measurement. The thermistor is secured in a ceramic housing for optimal temperature measurement. The device features an adjustable set-point with a range of -50°C to +120°C, programmable hysteresis, and an open-collector output of either +12Vdc or -15Vdc, which can easily be interfaced to a variety of control systems.

The LM57BISD-10/NOPB is designed for quick and easy installation. Itfeatures a DIN rail or panel mount with snap-in installation for most HVAC applications. It is also designed to be integrated with other monitoring and control systems, and comes with an integral remote temperature sensor.

The working principle of the LM57BISD-10/NOPB consists of a thermistor-based sensing element, ceramic housing, and adjustable set-point. The thermistor is a semiconductor device that changes its resistance in response to temperature changes. It is placed inside the ceramic housing, which is designed to provide optimal temperature measurement. When the temperature of the surface the device is measuring exceeds the set point, the thermistor will reduce its resistance, causing the output signal to change. This signal is then relayed to the ECU, which in turn can activate the appropriate system to adjust the temperature of the surface being monitored.

The LM57BISD-10/NOPB is an ideal solution for temperature monitoring applications requiring a compact, low-cost solution. Its robust construction, reliable performance, and adjustable set-point make it an excellent choice for a wide variety of HVAC, industrial and medical equipment control systems.
