FST-RH Magnetostrictive Displacement Sensor

Product · Customizable

Overview

A high-strength stainless steel probe rated to 34 MPa, outputting absolute position: after a power interruption the reading returns without re-zeroing. The sensing element is non-contact, so repeated measurement causes no wear — suited to continuous position feedback under high temperature, high pressure and vibration.

Features

  • Linear measurement, absolute output; 16-bit D/A resolution.
  • Non-contact, wear-free; LED fault indication.
  • Rugged and oil resistant, modular for easy maintenance; low power, low drift.
  • Non-linearity by range: 1%~0.5%FS (50~100 mm); 0.5%~0.1%FS (100~300 mm); 0.1%~0.05%FS (300~2000 mm).
