Difference/Sum LVDT Signal Conditioner

June 30, 2021   Don Horne


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 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 difference/sum measurement. These smart signal conditioners are RoHS compliant and CE-certified for use in Europe.

NewTek offers the NTC-6000 Signal Conditioner with a two-year warranty. The company accepts small- to large-sized orders and guarantees on-time delivery of units.  NewTek can accommodate customization requests to conform to a specific package, non-standard analog or digital outputs, and heightened environmental ratings.
