Product Overview
The GHS-19 Series Spring-Loaded LVIT Linear Position Sensor by Alliance Sensors Group is a low-cost, compact, high-performance gaging probe designed for dimensional measurements and position feedback applications. It is ideal for factory automation, PLC systems, test and measurement, and packaging equipment. This contactless sensor prevents internal wearout and offers excellent resolution and high stroke-to-length ratios. It is designed for drop-in installation in place of spring-loaded DC-LVDT gage heads and features proprietary SenSet field recalibration.
