HCA Series - Hermetically Sealed

The HCA Series LVDTs are tungsten-inert gas (TIG) welded to form a hermetic seal that is impervious to dirt, water, steam and corrosive liquids and vapors. They feature a glass-sealed, MS-type connector, but do not permit throughbore operation. (A right angle version – HCARA series -– allows the core and core rod to pass through the unit.) All exposed surfaces are stainless steel, including the boreliner and connector shell. Units can withstand external pressure up to 1,000 psi (70 bars). Double magnetic shielding resists external magnetic influences.
