amplifier signal conditioner / speed sensor
Model 4033 directional preamp for passive magnetic VRS sensors is designed to convert the sinusoidal signals from two matching magnetic VR type sensors into stable square wave pulses. It provides relative directional data from the two sensors through the signal out terminal and LED indicators. For prover applications, an (x2) output is provided, which is derived from the input of Coils A & B. It is designed to fit a GAUL-16 or similar standard explosion proof junction box.
