SENSOR SOLUTIONS /// HCA & HCA-RA Series Rev. 10
Hermetically sealed, all welded
Stainless steel housing
MS type connector, glass sealed
Axial or radial electrical connection
IEC IP68 rating to 1,000 PSI [70 bars]
Stroke ranges from ± 0.05 to ±10 inches
AC operation from 400Hz to 10kHz
Double magnetic shielding
Through bore design (HCA-RA version)
The HCA and HCA-RA Series hermetically sealed LVDTs provide
premium performance in harsh industrial environments. Impervious to
dirt, water, steam, and corrosive liquids/vapors compatible with its
materials, the HCA/HCA-RA 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. A high temperature operation (200ºC) model, HCA-T is also
available. The HCA/HCA-RA is compatible with the full line of
Measurement Specialties 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.
Like in most of our LVDTs, the HCA/HCA-RA windings are vacuum
impregnated with a specially formulated, high temperature, flexible resin,
and the coil assembly is potted inside its housing with a two-component
epoxy. This provides excellent protection against hostile environments
such as high vibration and shock.
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 PTFE sleeve allows low-friction travel through the stainless steel
boreliner (spool tube).
Also see our other hermetically sealed LVDT models with built-in signal
conditioning: HCD (DC voltage), HCT (4-20mA, 2-wire loop) and HC-485
(RS-485 Digital Series).
