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.

 

• Compatible with Hoffer Lo-Co series turbine flowmeters
• Choice of output: 0-10 VDC, 4-20 mA, 0-5 VDC, 0-10 VDC square pulse, or open collector
• Fits in compact ELBY explosion-proof enclosure with 1/2" and 3/8" NPT threaded connections
• Operating temperature range: -40° to 185°F (PET-1,- 3, -7) or -40° to 221°F (PET-4, -5, -6)
• Input sensitivity: 12 mVpp standard
