The LVDT/A and LVDT/D amplifiers provide a range of signal conditioning for LVDT and RVDT transducers.
They have also been used successfully with variable reluctance transducers, such as certain differential pressure sensors.
They are offered in two versions - the LVDT/A for 115/230V AC or 18-24V DC operation and the LVDT/D, which is DC powered only.
Transducer sensitivities between 20mV and 10V are accommodated by a combination of DIL switch settings and a fine trim potentiometer.
Similar arrangements are provided for any 'zero' errors in the transducers and can be used to offset the readings by up to +/-35 per cent of full scale.
A frequency response of typically DC to 200Hz is offered.
There is an on-board low pass filter, which can be switched in to reduce high-frequency fluctuations or induced electrical noise, to give stable readings under adverse conditions.
A range of output options for current and uni-polar or bipolar voltage can be configured by DIL switch settings.
Both the AC and DC versions are based on a common board and are mounted in a light grey ABS case, sealed to IP65 standard.
