Description

The GSA 750 series of short range spring loaded position sensors were developed for cost sensitive applications requiring LVDT reliability and performance. Available in ranges of ±0.10 inches to ±0.30 inches, these sensors offer the excellent measurement capabilities of an LVDT at very economical prices. This makes GSA 750 series LVDTs especially attractive for student projects, low over-head machine and fabrication shops, and R & D laboratories on a limited budget.

GSA 750 series sensors have a stainless steel housing and probe shaft, but utilize nylon sleeve bearings and an external helical spring to reduce costs. The LVDT's probe shaft accepts interchangeable AGD contact tips and is supplied with a number 9 hardened tip. The LVDT's body is encapsulated with epoxy to meet IEC IP-62 sealing requirements and magnetically shielded to reduce effects from external AC fields.

GSA 750 sensors are compatible with any of the Macro Sensors LVDT support electronics featured in series 9000 technical bulletins.
