Inductive Linear Transducer Series EVT

Inductive linear transducer in a robust miniature design

In the displacement sensor series EVT the mechanical detection of linear movement is done by a front guided push rod with accurate sleeve bearing and inside spring return device. The inductive measurement principle of the EVT is configured with a casted spool in LVDT winding and a transformation core mounted on the push rod. With an external electronic amplifier, our IMA2 LVDT, the position feedback signal of the core between the LVDT coils is transformed into the typical form of 0..10 V or 4..20 mA. Due to the contactless measurement principle long lifetime can be reached and permits high dynamic application, especially if small oscillating movement has to be detected. The inductive measurement delivers absolute values and is true power on. Because of his good linearity in view of small measurement strokes and high resolution also for movement in micro step the EVT sensor provides high accuracy. The stainless steel construction is realized in small housing dimenson with only 10 mm diameter and provides IP65 sealing protection. This combination of mini design, robust IP65 construction and high accuracy gives the inductive EVT series a high performance for linear motion measurement from 2  to 25 mm  with space saving integration even in heavy duty conditions. On request our pressure resistant and submersible EVT-W version with strong cable exit is available in measurement strokes from 2 to 25 mm.
