The GHNA19 series of rebound AC-operated LVDT sensors from ABEK SENSORS is suitable for a wide range of position measurement applications. The sensors are laser-welded in stainless steel housings with hermetically sealed coils and are IP-68 rated. They can withstand harsh environments and are suitable for a wide range of industrial applications.
The GHNA19 series sensors consist of a spring-loaded shaft running in a precision sleeve bearing connected to an LVDT core. Due to the precision sleeve bearing, measurements can be made with a repeatability of 0.6 microns or even lower.
The GHNA19R radial series has a through-hole design that allows the discharge of dirt adhering to the bearing. The probe head is freely retractable with a spring that can be adjusted from 100g to 500g depending on the environment. The probe is M3 threaded and can be used interchangeably with other probes.
The GHNA19 series are available for measuring ranges from 2.5mm to 100mm. They are characterized by high resolution, good repeatability, and low latency.
GHNA19 series are AC powered & AC output, that generally require a signal conditioner, more details for:LVDT/RVDT Signal Conditioner。
