Temperature Sensors - NTC Thermistors are widely used in many applications due to their excellent temperature response and wide temperature range. The PT103J2 is a NTC thermistor specifically designed for temperature sensing and control. It is a ceramic-encapsulated negative temperature coefficient (NTC) thermistor with a nominal resistance of 10 KΩ at 25°C.

The PT103J2 has a maximum working temperature of 125°C and a nominal operating range of -20 to +125°C. The thermistor is encased in a brass or ceramic housing and is constructed using a ceramic disc and a thin film resistor set in series. The resistor set is made up of a ceramic disc surrounded by a wire and a thin film resistor.

The PT103J2 consists of two components, the thermistor and wire assembly. The thermistor element consists of a disk of a silicon-based ceramic material containing a conductive element. As the temperature increases, the resistance of the thermistor decreases. The thermal coefficient is expressed as a negative value in common thermistors such as the PT103J2.

The wire assembly of the PT103J2 consists of two wires and a thin film resistor. The two wires are connected to the interrupting contacts of the thermistor and the resistor. The resistor\'s resistance value determines the range of temperatures that the thermistor is capable of measuring. The resistance of the resistor can be changed by changing the resistor\'s length or by changing the resistivity of the resistor.

The advantage of the PT103J2 is its extremely fast response time (<1 second) and accuracy in temperature sensing, which allow for accurate and reliable measurements over a wide range of temperatures (-20 to +130°C). The PT103J2 can be used in a variety of applications, such as in heating and cooling systems, food processors, water heaters, and freezers. The PT103J2 is also commonly used as a temperature probe in medical devices and general laboratory instruments.

The PT103J2 is typically used as a temperature sensing and control device in industrial process automation, such as HVAC, refrigeration, and domestic water systems. In these applications, the thermistor can be connected to a temperature-sensing circuit, such as a load control circuit, to provide information on the temperature of the environment. The thermistor can also be used to control the temperature of the environment, by activating a heater or cooling system when the temperature drops below or exceeds a predetermined temperature range.

The PT103J2 is easy to install and can be embedded into a moveable component or placed on a static board, allowing for flexibility in its application. The use of a plug-and-play cable assembly makes installation and maintenance easier. The temperature sensor is also easy to configure and configure for various functions.

In conclusion, the PT103J2 is a reliable NTC thermistor designed for temperature sensing and control. It is versatile and easy to install, with a fast response time and accuracy. It is suitable for a wide range of applications, such as HVAC, refrigeration, and general laboratory instruments. The PT103J2 is an ideal choice for those looking for reliable temperature sensing and control in their projects and applications.
