Gage Head

GA-750 Series

The NewTek GA Series gage head sensors are spring-loaded AC LVDTs with excellent linearity, high sensitivity and infinite resolution. Construction consists of stainless steel probe assembly and 0.750 inch diameter hermetically sealed housing. Designed for a wide range of position measurement and dimensional gaging applications, they are available in ranges of ±0.50 inch (1.27mm) to ±2 inches (50mm). The GA Series windings are potted inside its housing with a 2 component epoxy, providing excellent protection against hostile environments.
