Bestech Australia  offer the LVC 2500 LVDT signal conditioner, from Macrosensors, USA. This is a single channel signal conditioner that operates on 10 to 30 volts DC power to support standard LVDT, RVDT, and VRT half-bridge sensors.

The LVC 2500 LVDT signal conditioner is designed for use in 24 volt systems with PLCs, or in 12 volt mobile and vehicular testing systems. It offers the user a choice of three analogue outputs such as ±10 V DC, 0 to 10 V DC, or 4 to 20 mA (sourcing) current loop in a 3-wire common ground system in which the power ground is connected to the output signal’s ground.

The LVC 2500 LVDT signal conditioner 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 uses internal circuitry that produces a low distortion sine wave to excite the LVDT and employs a synchronous demodulator to convert the LVDT’s AC output signal to useful DC outputs proportional to core position.

By shifting a movable internal jumper in the signal conditioner, a user can choose 3, 5 or 10 kHz nominal excitation frequencies at a level of 3 Volts rms. The output non-linearity is less than ±0.01% of full scale output.

For multiple channel applications, several of these modules can be connected together in master/slave mode to synchronise their excitation oscillator frequency, thereby eliminating effects of heterodyning and spurious beat frequency signals, cross talk and intermodulation effects.In addition to its other features, this LVDT signal conditioner includes A+B, A-B, and (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 and average height.
