Non-contact Square-Drive Rotary Torque Sensor with Encoder

The RTSE non-contact square-drive rotary torque meter is a precision-engineered solution designed for dynamic torque and angle measurement in demanding industrial applications. Built using advanced strain gauge technology, this rotary torque sensor is integrated with an angle encoder, enabling simultaneous measurement of both rotational torque and angular displacement. It is ideally suited for torque auditing, tool calibration, and other high-precision torque monitoring tasks. The RTSE supports bidirectional torque measurement—both clockwise and counterclockwise—and is available in a variety of rated capacities: 5Nm, 10Nm, 15Nm, 20Nm, 30Nm, 50Nm, 100Nm, and 200Nm. This wide range makes it a versatile choice for industries ranging from electronics manufacturing to automotive assembly and beyond. One of the standout features of the RTSE is its non-contact signal transmission. The sensor is equipped with wireless electronics that allow it to transmit real-time torque data while rotating, eliminating the need for slip rings and significantly reducing signal noise and maintenance requirements. The sensor provides analog outputs including 0–5V, 0–10V, or 4–20mA for torque channels, and pulse output for angle channels, ensuring compatibility with various data acquisition systems and control units.

Additionally, the square drive interfaces on both ends of the RTSE torque load cell make it extremely easy to integrate with standard torque tools and testing setups. Its compact, robust design enables quick attachment to wrenches, screwdrivers, and fastening systems without the need for extensive modifications. Typical applications include:

• Torque Wrench Calibration: The RTSE is widely used in calibration labs and quality control departments for verifying and calibrating manual and digital torque wrenches, ensuring they meet industry standards for accuracy and repeatability.
• Electric Screwdriver Torque Verification: In electronics and small appliance manufacturing, maintaining consistent torque on fasteners is essential. The RTSE allows for real-time verification of electric screwdriver output, helping to maintain assembly integrity.
• Fastening Tool Performance Testing: The sensor is ideal for evaluating torque output and repeatability of various fastening tools under load, aiding in tool selection, validation, and preventive maintenance strategies.
• Automated Bolt Tightening Monitoring: In automated production lines, especially in the automotive and aerospace industries, the RTSE torque measurement sensor can be integrated into robotic arms or torque stations to monitor bolt tightening in real time, ensuring secure assembly and compliance with torque specifications.
• Torque Auditing in Assembly Lines: Manufacturers use the RTSE to audit the torque applied during production, either randomly or continuously, as part of a comprehensive quality assurance program.
• Power Tool Quality Control: Before shipping, power tools are tested for torque accuracy and stability. The RTSE torquemeter enables manufacturers to perform quick and accurate quality checks, reducing defective returns and enhancing brand reputation.

The RTSE rotary torque transducer offers a cutting-edge solution for real-time, non-contact torque and angle measurement. With its wide capacity range, wireless signal transmission, and square-drive integration, it stands out as a preferred choice for professionals seeking precision, efficiency, and adaptability in torque measurement applications. Torquemeter RTSE is not only accurate and easy to install but also customizable. For applications requiring unique mounting structures, non-standard capacities, or special environmental considerations, custom versions of the RTSE can be developed to meet specific needs.
