9100 Predetermining Rate Indicator

9100 Predetermining Rate Meter

Predetermining Ratemeter

The versatile 9100 multi-function instrument is a combined rate indicator and counter with network capability and back-lit display. The 9100 carries out rate measurement, batch counting and totalising simultaneously. Rate mode is signified by an R appearing at the top left hand corner of the display and counting carries on in the background. The first line of the display shows pulses per minute (PPM) unless a prescaler is in use.

Simultaneous operation in different modes, the LCD 3-line display, front-facing keys, network capability, enhanced programming, EEPROM memory avoiding the need for a battery, and on-screen programming prompts in four languages.

  • Simultaneously maintains any 3 of the following: Count preset, count pre warn, batch preset, overspeed, underspeed condition and displays count, total and speed.
  • Counts in any of 7 modes: A-B, A+B, A/B, count and direction and quadrature x1, x2 & x4.
  • EEPROM retains program and data for 40 years with no power.
  • 3 line Supertwist LCD display viewable from any angle.
  • Easily programmed in English, German, French or Spanish using simple menu structure and 10-key keypad.
  • Counting continues while rate measurement is in progress.
  • Accurate enough for position sensing and robotic control.
  • CAN bus/Device Net interface (as an option).
