LVDT Signal Conditioner - LVC-2500 by Bestech Australia

Supplier: Bestech Australia

Bestech Australia proudly introduces the Micro-Epsilon LVC-2500 LVDT signal conditioner. It operates on 10-30 V DC power and is compatible with both 12 and 24 V systems.

It has been designed for use in 24V systems with PLCs and mini-PLCs, or in 12V mobile and vehicular testing systems. It offers a choice of three analog outputs of 0 to ±10 V DC, 0 to 10 V DC  or 4 to 20 mA.

This LVDT signal conditioner from Macrosensors, USA is packaged in a DIN-rail mounting thermoplastic case with recessed screw-clamp terminals for all connections and multi-turn front-panel accessible span and zero adjustments. It produces a low distortion sine wave to excite the LVDT and employs a synchronous demodulator to convert the LVDT AC output to more useful DC outputs proportional to core position. It incorporates a 2-pole low pass output filter.

The external zero control permits output offset adjustment from -100% to +100% of full scale output of this LVDT signal conditioner. The span and zero controls do not interact with each other. The LVC-2500 does not require a phase adjustment control, so it can work satisfactorily with reasonably long cables between it and the LVDT.

For multiple channel applications, several LVC-2500 modules can be connected together in master/slave mode to synchronize their excitation oscillator frequency, thereby eliminating effects of heterodyning and spurious beat frequency signals, cross talk, and intermodulation effects. This LVDT conditioner includes A+B, A-B, (A+B)/2. Thus two LVC-2500 signal conditioners can be connected together along with a pair of LVDT gauging probes to measure differential dimension, thickness, average height, etc.

Features:

  • DIN-rail mountable
  • Analog voltage or current loop output
  • Non-interactive adjustments
  • No phase adjustment needed
  • Supports all standard LVDTs and VR half-bridge Sensors
