Secure Smart AC-LVDT Signal Conditioner for Power Generation Applications

Harold G. Schaevitz Industries LLC (HGSI) introduces its latest LVDT signal conditioner, the highly advanced S2A.  This LVDT signal Conditioner offers smart and fast LVDT/RVDT setup and has been engineered to work with the widest range of LVDTs, RVDTs, and inductive half-bridge sensors including 3-wire GE LVRTs and GE gas turbine buck-boost style LVDTs. The signal conditioning module has cyber security tamper prevention and notification features that no other manufacturers have even considered, providing confidence that the unit has not been compromised.

S2A LVDT Signal Conditioner Significant Features:

  • Cyber security to prevent tampering and notify main system operations of tamper attempt
  • Color coded plug-in connections
  • Self-diagnostics. 
  • Two year warranty 

S2A LVDT Signal Conditioner Operating Features:

  • Push button calibration
  • RS-485 digital communications
  • Hot swap capability
  • Enhanced Fault  Diagnostics


We are extremely excited about the release of the S2A. The marketplace has asked for several enhanced features, and our engineering staff has exceeded expectations and delivered a superior product for the Power Gen market compared to other manufacturer’s products.

The S2A has more system diagnostic capabilities than any stand-alone LVDT signal conditioner on the market. This LVDT Signal conditioner offers fault or failure detection for high reliability applications like nuclear power plant steam turbine controls. The S2A’s diagnostics can detect at least eleven (11) fault conditions. The S2A offers push button calibration, reducing set up time by a factor of 10. The internal microprocessor automatically sets up the LVDT signal conditioner. The operator simply presses the front panel Zero button and Full Scale buttons. The S2A is then fully calibrated with the LVDT position sensor. The S2A also can be setup remotely using a computer via its RS-485 port connected.
