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 version (200ºC) is also available (consult factory). 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.
