New Digital M40 Torque Transducers

The New Digital M40 Torque Transducers are used to measure constant or variable torque at the wide measuring range and the high speed rotation. They represent a new generation of torque transducers with advanced performance.

The Torque Transducers are designed without bearings and without slip-rings. They consist of two distinct components: a rotor and a stator. The rotor comprises a measuring body applied with strain gauges and two mounting flanges. It is equipped with the electronic system and a coil for transmitting the excitation voltage and the measuring signal. The stator includes the housing with electronics and two divisible rings of the stationary coil. The rings are fitted concentrically around the rotor with 3mm gap. The stationary coil and the rotating coil form an air transformer for inductive power supply and data transmission. The antenna system for data transmission is built into the coils. 

The M40 Torque Transducers are equipped with the advanced digital multi-channel telemetry system for contactless transmission of the measured torque data from the rotor to the stator and for a precise rotation speed measurement. Moreover, by means of telemetry additional physical parameters such as temperature of the rotor, lateral force, bending moment and the transducer’s unique identification number can be acquired. 

 Special features: 

• Operating on the strain gauge principle
• Measurement of static and dynamic torque with correct polarity
• Insensitive to lateral and axial forces and to bending moment
• Contactless transmission of data by means of digital telemetry
• Inductive power supply of rotor
• Built-in speed measurement system
• Analogue and digital output signal
