LD701 LVIT Linear Position Sensors for Low Ranges

Non-contact linear sensors have an analog output that is proportional to the damping target distance. Their compact yet sturdy design makes them suitable for industrial, robotics, and laboratory use. These sensors use inductive technology, which means they can sense any metal target. The sensing distance, however, is influenced  by the metal target. Ranges are calibrated using a standard square target. The target is mild steel  (Fe 360), 1 mm  (0.04") thick.  The side lengths are the larger of either the sensor’s face diaphragm or 3 times the sensing distance.

Sensing distances are influenced by metals other than mild steel. The “Correction Factors” chart, shown below, shows the reduction that occurs when brass or other target metals are used. For example, if the target were brass, the LD701-1⁄2 would sense 0.5 to 1 mm  (0.02 to 0.04"). The voltage output generated is directly linear to the distance being measured. The output can be read by panel meters, recorders, computer boards, or data loggers, all of which are available from OMEGA
