1/4" 3/8" 1/2" 3/4" 1" Square Drive Reaction Torque Sensor
The Flange-to-square Reaction Torque Sensor RTT06 is a high-precision device designed for direct torque measurement, particularly for torque wrench calibration, torque tool testing, and quality assurance applications. Its stationary design provides stable and repeatable torque measurement, making it suitable for professional calibration equipment and industrial testing systems.

Constructed from durable stainless steel, the stationary torque transducer RTT06 offers reliable mechanical performance in demanding working environments. A flange on one end allows the sensor to be securely mounted to a flat and rigid surface, while the other end is available with 1/4", 3/8", 1/2", 3/4", or 1" square drives. These square drive options allow convenient connection with torque sockets or sleeves for applying controlled torque loads during calibration and testing.
Based on proven strain gauge technology, this square torque transducer provides accurate and repeatable measurement with a non-linearity error of less than 0.2% full scale. Available rated capacities include 5 Nm, 10 Nm, 15 Nm, 20 Nm, 30 Nm, 50 Nm, 100 Nm, 200 Nm, 300 Nm, 500 Nm, and 1000 Nm. The RTT06 supports bi-directional torque measurement in both clockwise (CW) and counterclockwise (CCW) directions.
As a torque calibration sensor, the static torque meter RTT06 is well suited for verifying and calibrating mechanical torque wrenches and other torque-controlled tools. It can also serve as a torque tool calibration sensor in QA departments, production facilities, and automated assembly lines, where accurate torque verification is important for maintaining consistent assembly quality and tool performance.


The RTT06 can also be used as a torque testing transducer for torque verification, tool auditing, and industrial measurement applications. LCS TECH can provide customized configurations to meet specific project requirements, including different square drive sizes, torque capacities, mounting arrangements, and application-related modifications. With its robust stainless steel construction, flexible configuration, and high measurement accuracy, the RTT06 provides a practical solution for professional torque calibration and testing systems.
