The BT5-JA
CK from Chauvin Arnoux is a Pt100 temperature sensor with a jack plug connection, specifically designed for applications requiring precise temperature measurements. The sensor features a body made of polypropylene, which is chemically resistant and suitable for use in various industrial environments. It is commonly used in combination with conductivity or pH measuring instruments, as these measurements are highly temperature-dependent and require accurate temperature compensation to achieve reliable results.

Applications
This temperature sensor is designed for measurements in the range of 0 °C to +90 °C. This temperature range makes it particularly suitable for applications in laboratory and process measurement technology, especially in the food industry or for calibrating measuring instruments. The use of polypropylene as the housing material ensures high chemical resistance against many liquids, enabling the sensor to be used even in aggressive media.

Functions and Features in Detail
The BT5-JA
CK is based on a Pt100 resistance thermometer, in which the electrical resistance of platinum varies with temperature. The nominal resistance is 100 Ω at 0 °C, providing a standardized and reproducible measurement basis. The use of a jack plug enables a simple and secure connection to compatible measuring instruments, especially those equipped with a corresponding jack socket. The sensor’s design allows for rapid temperature response, which is advantageous for dynamic measurement processes.

Technology Explained Simply
A Pt100 temperature sensor utilizes the physical property of platinum, where its electrical resistance increases with rising temperature. This change is electronically detected and converted into a temperature reading. The accuracy of the measurement depends on the quality of the resistance material and the sensor’s construction. The polypropylene body ensures good thermal conductivity and simultaneous mechanical stability. The jack plug provides a robust and weather-resistant connection, suitable for use in industrial environments.

Compatibility and Accessories
The sensor is designed for use with devices that have a jack plug as an input interface. It is frequently used in combination with pH or conductivity measuring instruments, where temperature compensation plays a critical role. Use in a system with separate electrodes (e.g., measuring electrode and reference electrode) is possible, provided the device has a corresponding connection for the temperature sensor. Exact compatibility depends on the specific device configuration.

Mounting and Installation
Mounting the BT5-JA
CK involves simply inserting the jack plug into the corresponding socket on the measuring device. The sensor itself is immersed into the medium to be measured, ensuring that the sensing tip is fully submerged to guarantee a representative temperature reading. The polypropylene housing protects the sensor from mechanical damage and chemical exposure.

Operational Advantages
Using the BT5-JA
CK enables precise and reliable temperature measurement, which is crucial for the accuracy of pH and conductivity measurements. The combination of Pt100 technology and jack plug connection offers a robust and low-maintenance solution. The chemical resistance of polypropylene extends the sensor’s application range across various industrial uses. Its easy handling and rapid adaptation to ambient temperature increase efficiency during measurement procedures.
