This series of preamplifiers/signal conditioners is available in
a combination version that provides user selection of either variable reluctance VR or
RF sensor input.
When used with VR sensors they will accept low-level signals and provide hysteresis to eliminate
unwanted noise and interference. Operating range is 4 to 10,000 Hz. When used with RF sensors, they provide false pulsing safeguards,
air gaps up to 0.150", a frequency range of 2 to 5,000 Hz, as well as a precisely tuned carrier signal to allow for maximum signal
reliability.
