KT102J2 Temperature Sensors - NTC Thermistors

A KT102J2 temperature sensor is an NTC thermistor, a type of resistor whose resistance decreases as the temperature increases. This NTC thermistor has a negative temperature coefficient (NTC) of resistance, indicating that the resistance of the thermistor decreases by a certain percentage when the temperature increases. The KT102J2 thermistor is commonly used in temperature sensing applications due to its wide temperature range and excellent accuracy. It has a long useful life and is relatively inexpensive compared to other temperature sensors.

The KT102J2 thermistor is made of bismuth-tin alloy and has a round shape with an epoxy molded body. The epoxy molding helps reduce interference from environmental factors such as humidity, dust and oil vapor. The thermistor has a certified Curie temperature of 106°C and a resistance at 25°C of 10kΩ. The temperature range of the thermistor is -55°C to +125°C.

The KT102J2 thermistor is a two-wire device meaning it doesn’t need a separate power supply to operate. Instead, it draws power from a current source, such as a transistor or an operational amplifier (op-amp). The thermistor is connected to the two input leads of an op-amp and the output of the op-amp is connected to a voltage meter. Because of the thermistor’s NTC property, the voltage measured at the output of the op-amp will change when the temperature changes. By calibrating the voltage meter, the temperature can be determined.

The KT102J2 thermistor is used in a variety of temperature sensing applications, including process control, heating and cooling systems, and medical equipment. It is also used in automotive and aviation applications, as well as industrial installations and refrigeration systems. In addition, the thermistor is used in temperature measurement devices such as thermometers, thermocouples and temperature probes. It is also used in gas safety equipment and is suitable for use in hazardous areas.

The KT102J2 thermistor is an efficient and cost-effective temperature sensing solution. With its wide temperature range and excellent accuracy, it is well suited for a variety of temperature sensing applications. Its epoxy molding and certified Curie temperature makes it a reliable and durable temperature sensor that is sure to provide reliable temperature readings for years to come.
