TelMA Torque – Patented torque acquisition in stamp format

TelMA Torque enables dynamic torque measurement on rotating shafts using proven strain gauge technology in an ultra-compact “stamp format”. The sensor element integrates both the sensing function and the telemetry interface for contactless signal transmission and battery-free operation.

What it measures

Torque
Speed
Temperature

Key Benefits

Miniaturized dynamic torque measurement on rotating shafts
Compact torque element with integrated sensor and telemetry interface
No soldering or gluing process required
Series-friendly assembly via micro-welding (without affecting shaft strength)
Integrated rotation speed measurement
Optional bending moment compensation using 2 sensor elements
Analog or digital outputs with contactless transmission
Completely maintenance-free operation (battery-free)
Configurable measurement range via software (final configuration step after installation)
