LDM-1000
LVDT/RVDT Signal Conditioning Module

1. Introduction

The LDM-1000 is an extremely versatile LVDT/RVDT (Linear or Rotary Variable Differential Transformer) signal conditioning
module. The module supplies an AC sine wave excitation to the LVDT or RVDT, and demodulates, filters, and amplifies the
output. It is the perfect choice for industrial applications requiring the DIN standard rail mount.
