Miniature cylinders and actuators
Article Type: Mini features From: Sensor Review, Volume 33, Issue 2
Miniaturisation of sensors is equally important in other areas. Hydraulic and pneumatic cylinders, valves and actuators, for example, are becoming ever smaller and therefore require more compact, ultra slimline position sensors for measuring displacement and piston position. More robust, pressure-resistant position sensors are now required.
The sensors are manufactured from a pressure-resistant stainless steel (up to 450 bar), can operate to 165°C and withstand extreme vibration and shock levels. The sensor electronics and signal conditioning are completely integrated in the sensor flange using very compact electronics. Compared to an LVDT with similar measurement range, EDS sensors are typically 50 per cent shorter and much narrower in body diameter.
