Kistler Offers Sensitive And Robust Torque Sensors

Kistler's piezoelectric torque sensors have a wide measuring range and are adaptable to match most configurations, making them suited to manufacturing-process monitoring. The sensors are available with measuring ranges of 1, 10, 25, 200 and 1,000Nm and all are suitable for torques from approximately 0.001Nm.

The torque sensors are supplied calibrated for 100 and 10 per cent of the measuring range with additional calibration ranges available as an option. Installation is flexible as each sensor has an end flange with four or six threaded mounting holes and a centring seat for precise coaxial installation. A central hole allows a shaft to pass through the sensor.

The high sensitivity, rigid construction and compact dimensions of the sensors make them particularly suited to monitoring applications in assembly processes and product testing where rotary movements are involved: typically screw, bolt or nut tightening to specific torque; rotary potentiometer and switch testing; and screw-cap fitting.

As piezoelectric sensors are immune from fatigue and wear when properly used, their service life is virtually unlimited, making them suitable for use as calibration sensors and for general torque measurement in manufacturing and research-and-development applications.

Track Offers Robust Transportation Option

Machine Building Systems' new item transport track allows heavy goods to be transported easily and quietly. The transport track system tolerates soiling and is easy to assemble and can be added to any profile construction. Elevated transport tracks and suspended constructions are also possible.

A typical assembly would comprise an aluminium-profile constructed carrier onto which is mounted four D60 PU roller units, which run in a parallel pair of track profile 8 80x40s. The modular design means that the carriers can be made to any size and the track profiles placed accordingly.

The roller units (each with a load-bearing-capacity of 800N) are fitted with ball-bearing mounted polyurethane-tyres for smooth and quiet running and with spring-loaded lateral guide-wheels to provide sideways support.

The roller units offer a choice of fixing positions which can provide either a ride height which is flush with or 4mm from the track profile. The rollers can be used independently of the roller units and will run easily without the track profiles on level surfaces.
