DR-20

Product catalog summary
Product Overview: The DR-20 is a rotating slipring torque sensor designed by Lorenz Messtechnik GmbH. It offers nominal torque measurements ranging from 1 N·m to 500 N·m with high accuracy of 0.1% full scale. The sensor integrates speed and angle measurement capabilities and features a compact design with high torsional stiffness, making it reliable and easy to handle.
Specifications: The DR-20 sensor supports a range of nominal torques with corresponding limit speeds, spring rates, and mass moments of inertia. It operates within a nominal temperature range of 5°C to 50°C and a service temperature range of -10°C to 60°C. The sensor's accuracy class is 0.1% full scale, with repeatability at ±0.05%.
Electrical and Mechanical Details: The sensor requires an excitation voltage of 2 to 12 VDC for strain gauges and 5 VDC for angle measurement. It features a 12-pin electrical connection and is protected under IP50 standards. Mechanical dimensions vary based on nominal torque, with detailed measurements provided for different torque levels.
Options and Accessories: Available options include control signals and various calibration services, such as linearity diagrams and proprietary calibrations. Accessories include 12-pin connectors and cables.
Applications: The DR-20 is suitable for applications requiring precise torque measurement and is adaptable with special versions available upon request.
