  • Page 9: Application

    • 5725 is a digital indicator for readout of frequency signals and pulse signals. • Typical applications are indication and conversion of process speed measurements and flow rate. • The indicator can also be used for measuring the passing time on e.g. a conveyor line, as the 5725 can handle period time measurements. • Process control is possible as the type 5725D contains 2 pairs of potential- free change-over relays and an analogue output. • The display offers IP65 protection from the front and the splash-proof cover - PR type 8335 - can be used against atmospheres and liquids.
