Position feedback devices are commonly implemented in hydraulic applications for monitoring the performance accuracy of actuators and cylinders to improve operational efficiencies. The environment in which the embedded sensor must survive can be problematic. The hydraulic fluid is under high pressures and temperatures and the actuators and cylinders typically live in environments where heavy shock and or vibration are present.
Macro Sensors (http://www.macrosensors.com) offers the HSTA and HSTAR Series of LVDT-based linear position sensors that offer both the environmental resistance and short stroke sensor body length ideal to perform in cylinder applications where sensor length and survival in harsh environments are critical.
While linear position sensors were once considered too long for hydraulic applications, the development of new winding techniques, such as computerized layer winding and improved microprocessing, has considerably reduced the length of the linear position sensor body compared to its measurable stroke length. In fact, for short stroke actuators and cylinders (less than 6), Macro Sensors linear position sensors can be much shorter than a magnetostrictive sensor.
