Electronic torque meter plaroTorque®

plaroTorque® presents a unique system of its kind in the world in combination with the plaromaster® variable-speed gearboxes. plaroTorque® electronically determines the real torque available on gearbox output. It supplies universal actual value output as currency, voltage or field bus signal and it is flexibly programmable.

System overview

The planetroll® torque meter plaroTorque® enables to determine the real torque available on gearbox output shaft in consideration of the operating conditions. The influencing variables such as efficiency, temperature and voltage fluctuation, which are changing over the speed range are included here.

Ultimately, the plaroTorque® is a measuring system with a typical accuracy of +/-2 %, referring to full scale. If a reduction or transmission gearbox is used connected in series with the variable-speed gearbox, then the typical influencing variables mentioned above are calculated with torque. The torque determined by plaroTorque® is the basic principle for a sophisticated as well as a cost- and energy-saving calculation of drive units and furthermore it serves as process and characteristic value, i.e. in process engineering.

The application of plaroTorque® in test rigs or in test stands provides a precise knowledge of general efficiency, power requirements as well as efficiency of working machines.

As a matter of course, it is no problem to apply the plaroTorque® in explosion-proof areas, zone 1 and 21, according to ATEX 95.
