factory-direct torque sensor, built to the application-specific capacity and accuracy your project requires.
The WST1004 is a torque sensor. All figures on this page come from the factory parameter sheet — what you read here is what ships.
Contact our engineers for the complete datasheet and design-in support.
WST1004 Disc-type dynamic torque sensor, Rotational sensors (or dynamic torque sensor) are utilized in applications where the torque measurement must be taken at a spinning shaft, engine or a stationary motor. In this case, the transducer must rotate in-line attached to the shaft. A rotary torque transducer is fitted with a slip ring or wireless electronics to transmit the torque signal while rotating.
Rotary Torque Transducers are frequently used as testing/auditing tools for motors, torque measuring tool, turbines, and generators to measure rotational torque. A shaft-to-shaft Rotating Torque Sensor can be also utilized for feedback control, monitoring torque, and analyzing the efficiency of test stands and for torque measurement of rotating shaft using strain gauge.

Every unit is factory calibrated and inspected before dispatch; parameters on this page reflect shipped goods.
In-line between motor and load, the WST1004 measures static and dynamic torque in real time — for engine test stands, pump characterisation and gearbox QC.
Shaft-rotating
Driveshaft, halfshaft and rear-axle test rigs fit the WST1004 between the driven and driving halves to capture transient torque during shift events.
High RPM ready
Integrated into robot joint modules and collaborative robot wrists, the WST1004 closes the force-control loop for assembly, polishing and human-safe co-operation.
