LVDT Signal Conditioner

LVDT Signal Conditioner

Product catalog summary
Overview: The document provides technical specifications and details for the LVD 3 LVDT Signal Conditioner, designed for precise and rapid position measurements using LVDT transducers. It features two independent measurement channels, transducer excitation, and both voltage and current outputs.
Features: The LVD 3 includes two individual measurement channels, transducer excitation frequencies between 2.5–3.2 kHz, primary or sum feedback, voltage output options of 0–10 or ±10 V, current output of 4–20 mA, and a 24 VDC power supply. It is designed for quick installation on a DIN rail and is CE-marked for EMC compliance.
Description: The signal conditioner is developed for accurate position measurements with LVDT transducers. It consists of two identical, electrically isolated channels, each with an oscillator for AC excitation, inputs for position-sensitive signals, and an adjustable signal amplifier. Calibration is facilitated by switches, potentiometers, and test sockets.
Specifications:
  • Oscillator for Primary Coil: Frequency of 2.5–3.2 kHz, frequency stability of ±1%, and maximum voltage of 6 VAC.
  • Inputs for Secondary Coils: Maximum voltage of 6.8 VAC and minimum impedance of 150 kΩ.
  • Signal Conversion: Linearity of ±0.05%, offset adjustment of ±2 to ±7%, and gain range from 2.1 to 39.
  • Outputs: Current load of <500 Ω for 4–20 mA and voltage load of >6 kΩ for ±10 V or 0–10 V.
  • Power Supply: 24 VDC with ±20% variation, 200 mA slow fuse, and continuous current of <120 mA.
  • Environment: Operating temperature range of 0 to +50°C and storage range of –25 to +85°C.
  • Mechanical Data: Dimensions of 75 × 100 × 110 mm, DIN rail mounting, and IP20 protection.

LVDT Signal Conditioner-1

LVD 3 LVDT Signal Conditioner FEATURES • 2 individual measurement channels • Transducer excitation: 2.5–3.2 kHz • Primary feed-back or sum feed-back • Voltage output: 0–10 or ±10 V • Current output: 4–20 mA • Power supply: 24 VDC • Quick installation on DIN-rail • CE-marking, meets EMC DESCRIPTION Signal conditioner LVD 3 is developed for accurate and rapid position measurements by means of LVDT transducers. The module consists of two identical channels, electrically isolated from each other and from the power supply. Each channel has an oscillator that supplies the transducer with AC excitation, inputs for the two position sensitive signals from the transducer and an adjustable signal amplifier with current and voltage output. Calibration of LVD 3 and the connected LVDT transducers is easily performed by switches, potentiometers and test sockets on the module. LVD 3 is mounted on a DIN rail or any flat surface. All electric connections to the module are made through one plug-in terminal block for each channel.
