Pencil Type Transition Joint PT100 RTD Temperature Sensor

A. Product Overview

A Pencil Type Transition Joint Pt100 RTD Sensor is an industrial temperature sensor used to measure process temperature with high accuracy and long-term stability. The sensor uses a platinum resistance element known as Pt100, which has a resistance value of 100 ohms at 0 degrees Celsius.

The pencil type design makes the sensor compact and suitable for applications where direct insertion or fixed-point temperature measurement is required. The transition joint is the connection area between the sensing probe and the cable or process connection. This joint is designed to provide mechanical strength, protection and reliable signal transfer during temperature measurement.

These sensors are commonly made using stainless steel or other suitable materials depending on the process condition. For high temperature, corrosive or demanding environments, materials such as stainless steel or Inconel can be used for better durability and process compatibility.

B. Working Principle

The Pt100 RTD sensor works on the resistance temperature detection principle. The platinum sensing element changes its electrical resistance as the temperature changes.

At 0 degrees Celsius, the Pt100 element has a resistance of 100 ohms. As the temperature increases, the resistance of the platinum element also increases in a predictable manner. This change in resistance is measured by a temperature indicator, controller, transmitter or data acquisition system and converted into a temperature reading.

The transition joint helps protect the connection between the RTD element and the cable. It also supports stable signal transmission, especially in industrial environments where vibration, heat and mechanical stress may be present.
