- 1. Linear Position Sensors Spectra Symbol
Linear position sensors utilize noncontact and contact methods to measure the speed and/or
position of an object. They also use different sensing technologies for accurate measurement.
This device accurately measures displacement in control and monitoring systems. They are
used extensively in aviation, medical equipment, construction and agricultural vehicle and
automotive applications. Active Sensors offer a range of technologies that provide precise
measurements in high temperature, hostile environments. Our range of high performance
sensors include 'robust' sealed linear potentiometers, Pulse Inductive (PLS) contactless
transducers, LVDT sensors and Hall Effect linear sensors.
The linear position sensor has emitter and receiver coil systems, precisely placed onto a printed
circuit board, that are activated with a high frequency AC field and produce an inductive RLC
circuit with the positioning element (resonator). As a result, the resonator is inductively coupled
with the receiver coils. The receiver coils are arranged in a pattern so that different voltages are
induced into the coils depending on the position of the resonator. These voltages serve as a
measure for the sensor signal. These linear position sensor devices can be incorporated into
hydraulic/pneumatic cylinders, installed on circuit boards, or simply mounted to mechanical
assemblies.
There are so many varied applications that use a linear position sensor to work satisfactorily.
Whether it be monitoring pipelines on the seabed, or building an automobile, they all play their
part within the society we live in. As a rule, they usually go unnoticed, because we are so used to
using equipment that has them installed.
