PR 5725 Programmable Frequency Indicator

The 5725 measures, scales, and displays frequency signals found in many process speed and flow rate applications. The indicator can measure the period of the frequency, useful for displaying the elapsed time between events. The 5725D has two SPDT setpoint contacts and a 0/4…20 mA output for process control. The installed display provides IP65 environmental sealing, and additional protection is provided by the optional 8335 splash proof cover.
