About the HCA Series - Hermetically Sealed LVDT

The HCA/HCA-RA Series hermetically sealed LVDTs provide premium performance in harsh industrial environments. Impervious to dirt, water, steam and corrosive liquids and vapors compatible with its materials, the HCA/HCA-RA Series all-welded stainless steel construction withstands external pressures up to 1,000 PSI [70 bars]. Double magnetic shielding offers excellent protection from external electromagnetic fields.
The HCA/HCA-RA Series can be configured with a number of standard options including but not limited to high temperature operation (+220°C) and mild radiation resistance (1012 NVT total integrated flux; 107 rads Gamma). The HCA/HCA-RA Series is compatible with the full line of Altheris LVDT signal conditioners.

The HCA-RA version adds the convenience of a radial connector termination. This feature decreases the required installation space, while also allowing debris to harmlessly pass through the ‘open-ended’ bore.

Captive core option: The HCA/HCA-RA features an optional captive core design that greatly simplifies installation. The core rod and bearing assembly includes a Bronze bearing on the front end for self-alignment, while a Teflon sleeve allows low-friction travel through the stainless steel boreliner (spool tube). The core rod and the bearing assembly are both field serviceable.

Also see our models with built-in signal conditioning: HCD (DC voltage), HCT-IS (4-20mA 2-wire loop; CSA/FM Intrinsically Safe) and HC-485 (RS-485 Digital Series), also available in the -RA (Right Angle) versions.
