HCA & HCA-RA SERIES Hermetically Sealed AC LVDT SPECIFICATIONS 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. FEATURES The HCA/HCA-RA Series can be configured with a number of standard All-welded stainless steel options. A high temperature operation (200C) model, HCA-T is also available. The HCA/HCA-RA is compatible with the full line of construction Measurement Specialties LVDT signal conditioners. Glass sealed, MS type connector (MIL-C-5015) The HCA-RA version adds the convenience of a radial connector Shock and vibration tolerant termination. This feature decreases the required installation space, while also allowing debris to harmlessly pass through the open-ended bore. Captive core eases installation (optional) Like in most of our LVDTs, the HCA/HCA-RA windings are vacuum High temperature version available impregnated with a specially formulated, high temperature, flexible resin, (200C) and the coil assembly is potted inside its housing with a two-component Calibration certificate supplied with epoxy. This provides excellent protection against hostile environments each unit such as high vibration and shock. Right angle (HCA-RA) version Captive core option: The HCA/HCA-RA features an optional captive core available 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 APPLICATIONS boreliner (spool tube). Harsh industrial environments Also see our other hermetically sealed LVDT models with built-in signal Submersible (with appropriate conditioning: HCD (DC voltage), HCT (4-20mA, 2-wire loop) and HC-485 connector) (RS-485 Digital Series).
