MTS has developed the Temposonics M-Series especially for integration into hydraulic cylinders. The sensor is protected against shock, vibration and extreme environmental conditions and offers an unrivalled measurement rate, outstanding repeatability and stable linearity. 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 25 gav and shock resistance of more than 100 g. Changes of the hydraulic oil during operation are without effect on the measurement. The magnetostrictive technology of Temposonics sensors 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 M-Series offers continuous measurement of both - position and speed - during the position change. The integrated sensor electronics permits parameter adjustment for evaluation of the 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 actuators to be developed into complex movement axes and permits realization of high-quality control systems. With electro hydraulic parallel guidance of excavators or loaders, for example, Temposonics offer high signal quality and simple analogue transmission due to screening and a short signal lead.
