Pet Series Digital To Analog Converters

The PET Series converter receives frequency input and
converts it to a proportional 4-20mA or 0-10V analog
output.

It has been designed to fit a compact “ELBY”
explosion-proof enclosure. The frequency range is field selectable to fit most applications.

ZERO and SPAN
adjustments make it easy to calibrate to almost any
‘measurement range.

This PET is designed for use with
the Lo-Co Series and TriFlo Series flowmeters.

Pet Series Preamp Signal Conditioners

The PET Series mag-preamps are designed to convert low level sinusoidal signals into stable square wave
pulses.

The signal conditioners are built to fit a compact
“ELBY” type explosion-proof enclosure.

This PET is designed for use with the Lo-Co Series and TriFlo Series
flowmeters.
