Temperature Sensors are an integral part of many day-to-day operations, from machines such as refrigerators and air conditioners to instruments used in industries such as aerospace and biomedical engineering. They’re used to measure and monitor temperature, and often provide feedback information to a control system. One such type of sensor is a Positive Temperature Coefficient (PTC) Thermistor, the PTCSGM3T131DBE being one example.

This type of unit is mainly used for temperature detection and control in automotive, industrial and consumer equipment. It has a wide sensing range (from -40°C up to 125°C) and offers a low thermal time constant (less than fifty milliseconds). This makes it suitable for measuring temperatures in rapidly changing environments. It also has excellent vibration resistance, making it suitable for use in automotive and mechanical applications.

The PTCSGM3T131DBE is a glass sealed thermistor which operates on the principle of positive temperature coefficient. As the temperature rises, the resistance of the thermistor also rises. This makes it an ideal choice for temperature measurement and control applications. The unit utilizes a thin-film technology to provide a wide temperature range and speed of response required in high-reliability applications.

The working principle of the PTCSGM3T131DBE is based on the temperature-varying property of a semiconductor material, mainly cobalt manganese-oxide (see Fig. 1). This material consists of a temperature coefficient (TC) of resistance that is inserted into a glass coating material. At a low temperature, the resistance will be low. As the temperature increases, the resistance of the thermistor increases. This allows a specific temperature to be detected as the values across the thermistor cycles between high and low values.

The PTCSGM3T131DBE is usually connected in series with a power supply and can be used to provide feedback to a control system. A resistance-temperature curve is created when the thermistor is connected in series with a power supply and a multimeter is then used to measure the voltage across the thermistor. This data can then be used to create a resistance-temperature graph, giving the operator an understanding of the temperature values as they increase and decrease.

The PTCSGM3T131DBE is ideal for applications requiring a small temperature sensing range. It is also well suited for use in applications requiring higher temperatures and vibration resistance. This thermistor provides the necessary stability and accuracy to make it suitable for industrial and consumer applications. It is also relatively inexpensive and can provide accurate temperature detection over the specified range.
