Chauvin Arnoux BT5-DIN BT5 temperature sensor Pt100 / DIN plug content_copy

The BT5-DIN from Chauvin Arnoux is a Pt100 temperature sensor with a polypropylene body and DIN plug, specifically designed for integration into measurement systems where precise temperature detection is required. This temperature sensor is frequently used in industrial applications, particularly in conductivity and pH value measurements, which are highly temperature-dependent. Accurate temperature measurement is crucial to ensure measurement results remain consistent during calibration and measurement. The sensor enables measurements in the temperature range from 0 °C to +90 °C, making it suitable for many applications in laboratories and field environments.

Applications

The BT5-DIN is designed for use in environments where reliable and stable temperature measurement is required. It is particularly used in systems where the temperature of the sample or measuring medium must be continuously monitored to avoid measurement errors. Typical applications include the calibration of pH and conductivity meters, where the medium’s temperature directly influences the measurement calculation. The use of polypropylene as the housing material ensures high chemical resistance against many liquids, enabling use in various industrial and laboratory chemical applications.

Features and Equipment in Detail

The temperature sensor is based on a Pt100 resistance thermometer, in which the electrical resistance of platinum varies with temperature. The nominal resistance is 100 Ω at a temperature of 0 °C. This technology enables high measurement accuracy and stability across the entire measurement range. The sensor features a DIN plug, enabling a secure and standardized connection to compatible measuring devices. The use of a polypropylene body ensures high chemical resistance and makes the sensor suitable for use in aggressive media.

Technology Explained Simply

A Pt100 temperature sensor utilizes the physical property of platinum, where its electrical resistance increases with rising temperature. This relationship is linear and well-defined, allowing temperature to be accurately calculated from the measured resistance value. The designation “Pt100” refers to the resistance value of 100 Ohms at 0 °C. The measurement is performed via the DIN plug, which establishes an electrical connection to a measuring device that detects the resistance value and converts it into a temperature reading. The use of polypropylene as the housing material ensures high resistance to many chemicals, extending the sensor’s service life.

Compatibility and Accessories

The BT5-DIN is designed for use with devices that feature a DIN plug as the connection interface. It is specifically intended for integration into systems where precise temperature measurement is required, particularly in combination with pH or conductivity measuring instruments. The use of a DIN plug enables a standardized and reliable connection, which is common in many industrial and laboratory chemical applications.

Mounting and Installation

The BT5-DIN is mounted via the integrated DIN plug, which is inserted into a compatible device. Installation requires no additional tools or components. The sensor is directly immersed into the medium to be measured, with positioning ensuring the measurement point is fully submerged in the medium and no air bubbles or thermal bridges affect the measurement. The connection to the measuring device is made via the DIN plug, which ensures a secure and electrically stable connection.

Advantages in Operation

The BT5-DIN offers high measurement accuracy and stability across the entire temperature range from 0 °C to +90 °C. The use of polypropylene as the housing material ensures high chemical resistance, extending the sensor’s service life and enabling use in various chemical environments. The DIN plug connection ensures a standardized and reliable connection to compatible measuring devices, simplifying installation and maintenance. The combination of high accuracy, chemical resistance, and standardized connection makes the BT5-DIN a reliable partner in industrial and laboratory chemical applications.
