New torque sensor revs up to 50,000 rpm and has two ranges
The new type 4503A torque sensor from Kistler Instruments (www.kistler.co.uk) is designed to meet the demands of testing at high speeds in both production quality control and development.
Typical applications include testing of electric motors, generators, drive performance, measurement of transmission or spindle drive friction, at a manual workstation or in networked, automated production cells.
Available in fourteen measuring ranges from 0.2 to 20 Nm with a rated speed of 50,000 rpm and 50 to 5,000 Nm at 30,000 rpm, all with an integrated speed sensor output of up to 360 pulses per revolution. Both analogue and digital outputs are provided by the integral, digital signal conditioning system making the new sensors ideal for use in laboratory, development, production or quality assurance applications.
The option of two, switchable ranges, with the second range being either 1:10 or 1:5 of the rated torque, allows very precise measurement of both peak and operating torque with the one sensor. In applications with a high peak but moderate operating torque, a sensor with only one measuring range would have to be chosen to withstand the peak torque. As a result, it would be oversized for accurately measuring the lower operating torque.
The contactless power and signal transmission between the rotating shaft and the stator, combined with precision manufacturing, low production tolerances and high grade shaft balancing, essential for reliable, high speed operation, ensure that the sensors maintain calibration over a long life.
Established in Winterthur (Switzerland) in 1957, the Kistler Group now has a worldwide presence with 25 group companies and 30 distributors ensuring prompt, local application support and short delivery times. With a staff of more than 1050, the Kistler Group is one of the world's leading providers of dynamic measuring instrumentation with a turnover of 210 million Swiss Francs (GBP 145M) in the 2010 financial year.
Kistler's core competence is the development, production and use of sensors for measuring pressure, force and acceleration. Kistler's know-how and electronic systems can be used to prepare measuring signals for use in analysing physical processes, controlling and optimising industrial processes, improving product quality in manufacturing and improving performance in sports and rehabilitation.
Kistler offers a comprehensive range of sensors and systems for engine development, automotive engineering, plastics and metal processing, installation technology and biomechanics.
Heavy investment in research and development, 15% of staff worldwide are engaged in research and development, has generated a number of innovations using piezoelectric, piezoresistive and capacitive techniques to provide solutions to numerous force, pressure and acceleration measuring problems. These innovations include the world's first commercial quartz sensor, two-wire constant current technology to integrate sensors with microelectronic circuitry, high-temperature pressure sensors for use up to 400 Deg C and three-component force measuring sensors.
