Torque Sensors by Lorenz Messtechnik GmbH

We offer rugged and reliable torque sensors (torque transducers or transmitters) in various versions and measurement ranges in accordance to the respective application requirement. For example, part of our product range are torque sensors in reactive, non-rotating; rotating with slip rings, or non contact transmission; with optionally integrated speed/angle measurement; rotor with bearings or bearingless rotor; as shaft version in round, square, hexagonal, flanged or special designs. In addi­tion, we offer an extensive selection of accessories, such as couplings, measuring cables, measuring amplifiers, ... .


Rotating Torque Sensors with non contact Transmission

    Torque transducers with non contact transmission are supplied as active sensors with integrated measuring amplifiers; as output signals, analog ±5V by default, ±10V optionally, or digital RS485 or USB are available.
    By the non contact transmission, the measurement data are transmitted maintenance-free and without signal distortion between rotor and stator. Integrated speed/angle measurement is available as an option for al­most all non contact sensors.
    Mechanically, our non contact transducers can be divided in 2 sections: sen­sors with bearings and bearingless sensors.
    The advantage of bearingless transducers is that bearing friction cannot falsify the measurement result and they are usually designed for higher speeds.
    For digital sensors, we distinguish 2 product groups: sensors with RS485 interfaces or transducers with USB interfaces.
    RS485 torque transducers are characterized by a particularly high noise immunity, even with very long connection cables. For displaying, our USB sensors do not require additional and often expensive and complicated to use measuring amplifiers. Via plug-and-play, the transmitter can be eas­ily connected to a standard PC. Before initial operation, only the USB driv­er, included in the scope of delivery, as well as the configuration and anal­ysis software must be installed on the PC.
    Typical applications for this sensor type are for example screw driving technologies, test bench applications such as the examination of en­gines, gears, bearings and seals, … wherever high speeds in continuous oper­a­tion and standardized output signals are required on sensor side.

    Torque Transducers with Non Contact Transmission


    For our torque transducers, we provide corresponding couplings, cables and much more.
    For our passive sensors we offer e.g. measuring amplifiers, such as sensor interfaces for the conversion of the bridge output signals into standar­di­zed voltage or current signals for the connection to stan­dard interfaces; or measuring amplifiers with integrated displays for direct presentation of the measured values.
