Temperature Sensor is a one of the sensor that measure temperature, like any other application sensor.DC95F502Z is one of the temperature sensors, also known as NTC Thermistors, which has its own application field and working principle.

NTC thermistors are temperature dependent resistors widely used in temperature measurement and regulation applications because it has a negative temperature coefficient of resistance. This thermistor is made up of more than a thousand metal oxide particles blended with a low melting temperature glass binder to form a spherical bead. When mixed with an electrical circuit, the DC95F502Z thermistor can then be used to measure ambient temperatures from -40°C to 250°C.

DC95F502Z thermistors have a wide range of applications, including over-temperature protection on power supplies, power amplifiers, and other sensitive electronic components, management of system thermal shutdowns, liquid level detection, and environment temperature sensing. DC95F502Z are also frequently used in medical equipment, home appliances, and in automotive systems. For each application, an appropriate thermistor model and suitable circuit connection must be selected.

Like other thermistors, the operating principle of the DC95F502Z is based on how resistance decreases with increasing temperature. A precise thermistor circuit must be designed as a means to accomplish the request of temperature measurement. Its operating circuit mainly includes a temperature sensitive thermistor, a reference resistor, and an operational amplifier. An input DC voltage is applied to the thermistor and reference resistor in series, with the output signal reflecting the thermistor resistance relative to the reference resistor. The output voltage signal is then amplified quantitatively by the operational amplifier, and then available for further temperature-signal processing.

In conclusion, DC95F502Z is an NTC thermistor which can be used across a wide range of applications from -40°C to 250°C. It operates on the principle of a decreasing resistance with an increasing temperature, and consists of a thermistor, a reference resistor, and an operational amplifier. The output voltage signal is then amplified quantitatively by the operational amplifier, and then can be used for further temperature-signal processing.
