About the HCI-Series Hermetically sealed, high input impedance AC LVDT

The HCI 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 HCI 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 HCI LVDTs have a high input impedance making them well suited for interfacing with loop powered (2-wire 4-20mA) signal conditioners. The HCI is the LVDT series that is offered as part of our CTS-420 system. All stroke ranges have about the same output at full scale.

Other features HCI-Series

  • All-welded stainless steel construction
  • Glass sealed, MS type connector (MIL-C-5015)
  • Calibration certificate supplied with each unit

Applications for HCI-Series

  • Harsh industrial environments
  • Submersible (with appropriate connector)
  • Pressure vessels
  • Corrosive liquid and vapor areas (check materials)
  • Turbine valve
