The GHTA19 series of rebound high-temperature AC-powered LVDT position sensors are widely used in position measurement fields. The sensors are laser welded in a stainless-steel housing, the coils are hermetically sealed, and the whole machine can achieve IP-68 protection. This series is produced with special materials and processes, and can work continuously and stably at a high temperature of 200°C.
The GHTA19 series LVDT sensor consists of a rebound shaft that operates inside a precision sleeve bearing and is connected to the LVDT core. Due to the precision sleeve bearings, measurements can be carried out with repeatability of 0.6 um or less.
The GHTA19 series sensors are available in ranges from 2.5mm to 100mm. It has the characteristics of high resolution, good repeatability, and low latency.
The GHTA19 series offers a variety of technical specifications for customers. In addition to the options provided in the selection table, it can also be customized according to customer requirements, including radiation resistance, Teflon（PTFE）core bushing, thread specifications, wiring methods, connector types, and other mechanical structure needs.
GHTA19 series are AC powered & AC output, that generally require a signal conditioner, more details for:LVDT/RVDT Signal Conditioner。
