Low-cost torque sensor uses strain gauges

Paul Boughton
Kistler's Type 4520A... Basic Line is a cost-effective torque sensor based upon strain gauge technology. It extends the company's broad range of sensors for tasks requiring efficient torque measurement. The sensor Type 4520A... is suitable for use in production, quality control and the laboratory.
Non-contact transmission of power and data makes the sensor robust and maintenance-free in continuous use. It measures torques in accuracy class 0.5 at speeds up to 10,000 revolutions per minute.
The Type 4520A... sensor is offered with rated torques of 1/2/5/10/20/50/100/200/500/1000Nm and, in addition to the +/-10V torque signal, features a speed output with 60 pulses/rev (TTL) as standard, plus an externally switchable 100  per cent control signal.
In addition, Kistler's Como Torque (Type 4700A...) evaluation instrument and Sensortool (Type 4706A) PC software are available for evaluation and parameter configuration.
