Product Description

HCD Series
Hermetically Sealed

Description :
The HCD series LVDTs are impervious to dirt, water, steam spray and most corrosives. Tungsten inert gas (TIG) welding provides hermetic sealing that is free from oxidation-producing faults that may cause leakage. They have been qualified at pressures up to 1000 psi (70 bars) and are suitable for numerous high-pressure applications. They are terminated with a glass-sealed, MS-type terminal connector. The connector prohibits the core from passing completely through the coil assembly. HCD units have double magnetic shielding that makes them insensitive to external magnetic influences.
