MTS HD‑522 LDT Signal Conditioning Module

The MTS HD‑522 is a high‑performance signal conditioning module designed for LDT magnetostrictive linear displacement transducers. It receives position signals from magnetostrictive sensors and converts raw pulse signals into standard analog outputs, delivering accurate linear‑position measurement for industrial motion‑control systems.

This DIN‑rail mounted unit supports multiple output modes and provides sensor fault detection function. It serves as important aftermarket spare for maintenance, overhaul and retrofitting of hydraulic equipment, material‑handling and automated production‑line systems.
