Absolute magnetostrictive linear position sensor for mobile hydraulics 50-2500 mm, 100g, 0,005% F.S.
MTS has developed the Temposonics M series especially for integration into manufacturer of hydraulic cylinders. The sensor is protected against shock, vibration and extreme environmental conditions and offers an unrivalled measurement rate, outstanding repeatability (better than +/- 0.005%) and stable linearity (better than 0.04%). External effects on the measurement signal are virtually excluded by interference suppression for HF electric fields up to 200 V/m, vibration resistance up to 30gav and shock resistance of more than 100g. Changes of the hydraulic oil during operation are without effect on the measurement. The magnetostrictive technology of Temposonics detection was invented by MTS and widely used and well proven in stationary industrial applications for many years. The magnetostrictive measurement principle is a warranty for wear and maintenance free absolute, contactless position measurement.
Temposonics MH offers continuous measurement of both - position and speed - during the position change. The integrated sensor electronics permits parameter adjustment for evaluation of the professional cylinder piston speed and end position attenuation can be omitted. Due to the output of a velocity signal, highly dynamic control of the movement profile of several independent hydraulic cylinders is possible for the first time. It enables the power manufacturers of actuators to be developed into complex movement axes and permits realization of high-quality control systems. With electro hydraulic parallel guidance of professional excavators or loaders, for example, Temposonics offer high signal quality and simple analogue transmission due to screening and a short signal lead.
