MC-18

MC-18 Synchronic: 

  •  Volumetric working principle
  • RPM adjustment, additive feeder
  • Synchronized tacho mode for automatic speed compensation
  • Low investment, high savings
  • Accurate and reliable, 5 years warranty

 

MC-18 controls were designed to set metering speed and metering time manually. Also, the synchronized tacho mode can slave the MC-18 to your extruder for automatic speed compensation. The integrated automatic voltage selector ensures consistent operation even when there are fluctuations in the power grid. The standard integrated hopper loader controller enables you to work with Movacolor automatic hopper loaders, ensuring adequate supply of material at all times. OFF alarm can be generated as an option.

Calibration Method/ControlsThe required metering system rpm needs to be tested by manual deduction. When testing off-line the TEST button will run the unit at the set parameters. The measured value needs to be re-evaluated with the required set point. When required, metering speed must be adjusted. This procedure is repeated until the required set point is achieved.

 

Controls
Speed: Manual setting from 0 to 200 rpm max, in increments of 0.1 rpm.
Time: Manual setting from 0 to 999 sec in increments of 0.1 sec.
