NTC thermistors are temperature sensors used for measuring temperature with an accuracy of 0.5°C or better. They are most commonly used in industrial, automotive, aerospace, and medical applications. The NTC thermistor PW303J2 is a highly sensitive temperature sensing device that can be used to accurately measure temperatures in a wide range of environments. It is ideal for applications such as HVAC and refrigeration systems, automotive and climatic controls, and a variety of medical solutions.

The PW303J2 is designed for precise measurement of temperature and the sensing element is calibrated to a reference temperature. The calibration of the PW303J2 is a two-point calibration method that allows for a wide range of temperatures with excellent accuracy. This calibration range is ±2°C and the linearity ranges within 0.1°C of the setpoint temperature. The device operates in a temperature range of -55°C to +150°C, with a maximum accuracy of ±0.5°C.

The PW303J2 thermistor is designed using a special ceramic material and is protected by an epoxy coating. This results in a robust and reliable device that is designed to withstand harsh environmental conditions. The device also has a low thermal mass, meaning that it heats and cools quickly and responds to temperature changes quickly. This makes it ideal for capturing detailed temperature measurements in a variety of environments.

The device’s sensing element is made of a combination of metal oxides. As the temperature of the element changes, so does its electrical resistance. It then converts the temperature into an electrical signal for processing. This is done using a Wheatstone bridge circuit that is comprised of two resistors, a thermistor, and a fixed resistor. As the resistance changes due to the temperature, the voltage across the bridge changes as well. This voltage is then converted into a temperature reading by a microcontroller, which then sends the signal to the user’s system.

Overall, the PW303J2 is a highly accurate and reliable thermistor for temperature sensing applications. It has excellent accuracy and is designed to be reliable and robust in harsh environments. The two-point calibration method allows the device to measure temperatures within its specified range accurately, and the low thermal mass ensures it responds quickly to changes in temperature. With its quick response and accurate measurements, the PW303J2 is perfect for a variety of temperature sensing applications.
