Difference/Sum LVDT Signal Conditioner improves sensor performance over large temperature variations

July 13, 2021
NewTek Sensor Solutions introduces a new series of Difference/Sum LVDT Signal Conditioners, ideal for use in harsh environments with extreme temperature swings.

NewTek Sensor Solutions introduces a new series of Difference/Sum LVDT Signal Conditioners that improve a 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 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 difference/sum measurement. These smart signal conditioners are RoHS compliant and CE-certified for use in Europe.
