Hoffer PET Series Digital to Analog Converters and Preamp Signal Conditioners
Hoffer PET series converters and signal conditioners are designed to fit a compact ELBY explosion-proof enclosure, for use with the Hoffer Lo-Co series of economical turbine flowmeters.
PET series converters receive frequency inputs and convert them to proportional 4-20 mA or 0-10V analog outputs. They include zero and span adjustments, making the PET easy to calibrate to almost any measurement range. PET series mag-preamps convert low level sinusoidal signals into stable square wave pulses.
