Variable reluctance linear position sensors and switches are non-contact devices. Variable reluctance sensing incorporates a "spring" of elastic, highly magnetically permeable material surrounded by two coils. Variable reluctance linear position sensors and switches use strain-based technology, wherein a magnetic circuit is formed, and the parameter input causes mechanical deflection of the spring member as a function of pressure, force, or acceleration. The deformation, strain, or displacement of the spring results in modulation of the inductance of the two coils, and this is read to indicate force, pressure, position, or other input to the sensor. |
Products & Services Related to Linear Position Sensors and Switches, Variable Reluctance
Cable Extension Linear Position Sensors
Cable extension linear position sensors are used to measure the movement and displacement of objects. A cable or wire is attached to an object, and as the object moves, the transducer produces an electrical signal proportional to the wire's linear extension.
Linear Position Sensors, LVDT
Linear variable differential transformer (LVDT) linear position sensors have a series of inductors in a hollow cylindrical shaft and a solid cylindrical core. These devices produce an electrical output proportional to the position of the core
