KC103J2K

Temperature Sensors - NTC Thermistors

NTC thermistors are a type of temperature sensor that uses an exponential non-linear resistive temperature coefficient. They are highly accurate, fast-responding, and non-linear resistance devices that are popular for temperature-sensing applications. Typically, an NTC thermistor is connected to an AC source, such as a distributed control system (DCS) or programmable logic controller (PLC) device, in order to provide accurate temperature readings.

KC103J2K Application Field and Working Principle

The KC103J2K is an NTC thermistor designed to provide fast-responding, accurate temperature readings for industrial and commercial temperature-sensing applications. This device features an epoxy-sealed package that is compliant with FM Class I Division 2 requirements when properly mounted and configured. It features a resistive temperature coefficient (RTC) of -4.93°/°C and an operating temperature range of -5°C to +60°C.

To use the KC103J2K, the thermistor is connected to a DC power source. The device accepts an analog input through its three pins: two pins are used for the input voltage, and the other is used as the output voltage. When the input voltage is applied, the thermistor’s resistance varies according to the difference between the input and output voltage, thereby providing a temperature reading. The temperature reading can be read by a compatible device, such as a DCS or PLC, and is used to make temperature-related decisions.

The main advantages of the KC103J2K are its accuracy, fast-responding time, and FM Class I Division 2 ratings. The thermistor provides accurate temperature readings, and its response time is on the order of milliseconds. Additionally, since it is FM Class I Division 2 rated, it can be used safely and reliably in hazardous locations.

The KC103J2K is also easy to install and configure. It is epoxy-sealed and comes with features that allow for easy connection to existing wiring. Additionally, the device can be configured to provide a voltage output, current output, or resistance output, depending on the application requirements.

Conclusion

The KC103J2K is an accurate and reliable NTC thermistor that provides fast-responding temperature readings in industrial and commercial applications. It has a resistive temperature coefficient (RTC) of -4.93°/°C, an operating temperature range of -5°C to +60°C, and is FM Class I Division 2 rated. The device is easy to install and configure, allowing users to quickly and reliably get temperature readings for their applications.
