USED RDP ELECTROSENSE GT2500-1.25

The RDP Electrosense GT2500-1.25 is a precision miniature LVDT (Linear Variable Differential Transformer) gauging transducer designed for high-accuracy displacement and position measurement. Based on the GT2500 platform with a ±2.5mm (±0.1") measurement range, it employs precision linear bearings for optimized repeatability and uses a spring-return armature mechanism — ideal for applications where direct mechanical connection to the measured component is not possible. The "-1.25" suffix designates a 1.25m integral cable configuration (variant from the standard 2m), offering the same performance in a compact stainless steel rod-profile housing with infinite resolution and no electrical contact across the sensing element.
