Difference/Sum LVDT Signal Conditioner Improves Sensor Performance Over Large Temperature Variations

Pennsauken, NJ, June 30, 2021… NewTek Sensor Solutions introduces a new series of Difference/Sum LVDT Signal Conditioners that improve the sensor’s performance during large temperature variation.   By measuring the difference of the output over the sum (S1-S2)/(S1+S2), the NTC-6000-DS Quick-Cal™ LVDT Signal Conditioner compensates for changes in resistance in copper windings due to temperature fluctuations.  As a result, the Ratiometric Signal Conditioner is ideal for use with AC- LVDTs in harsh environments with extreme temperature swings such as aerospace test stands, packaging equipment, factory automation, turbine control systems and steam valve positioning.


Users of the NTC-6000-DS LVDT Signal Conditioner can select between a ratiometric Diff/Sum measurement or differential (standard) measurement.  Based on the proven and reliable platform of the NTC-6000 LVDT Signal Conditioner, this standalone unit offers:


  • Selectable ratiometric Diff/Sum measurement or differential (standard) measurement
  • Compatibility with almost any AC-LVDT
  • Self-diagnostics for sensor failures, disconnects or short circuits
  • Cybersecurity locks out and tamper detect
  • Voltage, current and digital
  • Digital protocols include Modbus, CAN Bus, RS-485 and more
  • Hot swap reconfiguration where setup is saved and reloaded via the RS-485 port
  • Intuitive setup for quick configuration by non-technical personnel
  • Selectable excitation frequency, analog outputs and bandwidth

The NTC-6000-DS LVDT Signal Conditioner is compatible with standard and constant sum AC LVDTS and RVDTs including NewTek’s NT-HT-1000 High Temperature LVDT Position Sensor Series designed for diff/sum measurement.  These smart signal conditioners are RoHS compliant and CE-certified for use in Europe.
