TelMAX Torque – Easy-to-Install Powermeter System (No Soldering / No Gluing)

TelMAX Torque is an easy-to-install powermeter system for torque measurement on rotating shafts—without soldering or gluing. The torsion sensors are micro-welded onto the shaft in minutes, providing maintenance-free, battery-free operation with contactless data transmission and CAN/analog outputs.

TelMAX Torque – Easy-to-install torque measurement without soldering and gluing

TelMAX Torque is designed as an alternative to conventional sensor and telemetry applications, especially for large machinery, agriculture, and drive shafts for trucks and construction equipment. Installation is fast and suitable for retrofitting, even in harsh environments.

What it measures

Torque
Speed
Temperature

Key Benefits

Installation in ~3 minutes using micro-welding technology
No wiring, soldering, or gluing needed
Works with one or two sensor elements (two enable automatic bending moment compensation)
Battery-free and maintenance-free after welding
High signal sampling rate: 1000 samples/sec for dynamic torque detection
Inductive energy and data transmission across an air gap up to 10 mm
Insensitive to magnetic fields (no issues with shaft currents in hybrid/electric drives)
No influence from shaft displacement or radial vibrations

Stator Evaluation Unit

Robust IP67 evaluation unit with integrated stator antenna
Supply voltage 9–30 V for flexible applications
Configurable/calibratable within seconds using MANNER software “Telemetry Interface”
