Relays, analogue output, digital display

The DF-K evaluating electronics out-puts the sensor frequency signal to a display, and converts it to an ana-logue signal and two limit contacts. The top display line of the double-spaced display shows the flow value with measuring unit and the bottom line a bargraph indicator propor-tional to the measuring value. The two relays with floating output change over contacts continously monitor the flow values. Switching point, hysteresis, a window point, and switch on or off delay can be set separately for each relay. The switching points can also be set di-rectly by using the control keys  with - out having to change over into the menu. A red LED indicates with the switching status.

The analogue output is optionally available as current output with 0(4)...20 mA or as voltage output with 0...10 V. A MIN/ MAX reading memory determines the extreme readings of the flow. If the maximum set flow (exceeded range) is exceeded, it will be shown on the display. The set parameters can be pro tected against unauthorised alteration by using a password function.

The device is connected with a 10-pin cable.
