  • Description

    This high precision torque sensor is designed for both static and dynamic measurements on non-rotating applications. It is particularly suitable for torque measurements on, for instance, extremely small electrical actuating drives and micro-mechanical actuator elements, or for measuring reaction torques e.g. on micro-motors.

    The high accuracy of measurement also makes this sensor ideal for use as a reference in many fields of industrial manufacture, or in laboratory research and development projects. Not containing any rotating parts, it requires no maintenance if properly used.

    Available accessories include mounting brackets and flange adapters, which enable quick, easy and practical integration of the sensor into existing or newly developed setups and test benches. Other possible applications:

    • Test setup for precision mechanics
    • Measuring the frictional torque of bearings
    • Measuring the torques applied to vehicle control elements and knobs
    • Acquisition of breakage moments on screw caps

    The strain-gauge based sensor’s modular design allows precise configuration for the desired application: 

    • mV/V with standardized output signal
    • ± 10 V output signal, configuration via USB
    • ± 10 V output signal, configuration and measurement via USB

    With the integrated amplifier option, the sensor directly supplies a voltage signal of 0 ... ± 10 V that is proportional to the torque. The sensor can be configured via the micro-USB interface, providing access to, for example, a filter frequency setting, averaging, and a tare function. With the USB option, in addition to the voltage output, the measurement function is available via USB as well. The supplied DigiVision software can be used for measuring and storing data, or alternatively drivers for e.g. LabVIEW are available. Integration into custom software is possible via DLL.

    The burster TEDS option (electronic data sheet, memory chip with sensor-specific data) allows rapid configuration of compatible evaluation units (instrumentation amplifier, indicator, ...).
