Telemecanique XMLP400BD71F Pressure Sensor: 400 bar Industrial Pressure Monitoring with 4–20 mA Output
Accurate pressure monitoring is a critical parameter in hydraulic systems, industrial automation platforms, and heavy-duty machinery. The Telemecanique XMLP400BD71F pressure sensor is engineered to provide stable and precise pressure measurement up to 400 bar, making it suitable for demanding hydraulic and fluid control applications. With a 4–20 mA analog output and M12 connector interface, this sensor integrates efficiently into PLC-based control systems that require continuous process feedback.
The Telemecanique XMLP400BD71F pressure sensor belongs to the XMLP pressure sensing family, designed for industrial environments where reliability, mechanical robustness, and electrical stability are essential.
Pressure Measurement Principle
The Telemecanique XMLP400BD71F pressure sensor operates using a piezoresistive measurement principle. Internal sensing elements convert applied pressure into a proportional electrical signal. This signal is then conditioned to provide a standardized 4–20 mA analog output, ensuring compatibility with industrial analog input modules.
Because the output is current-based rather than voltage-based, the Telemecanique XMLP400BD71F pressure sensor maintains signal integrity over longer cable distances and in electrically noisy industrial environments.
