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.
