It is a position sensor that is used tokeep the guide roller in its center position.Centering nozzle CN12 (for the MK.IV.D))Decompression device RD-G (optional) for plant air ServoguidesThis center-position sensor can be used to maintain thewinding and unwinding reels in central positions,andcenter the guide rollers when web threading. Settingthe selector switch to CENT switches off the signalvoltage from the measurement nozzle so that onlythe air pressure from the blower is transmitted to theServoguide MK?IV diaphragm. Air is discharged tooperate the cylinder until the center position of the reeland guide roller is maintained constantly.A device to reduce air pressure supplied from theprimary side to the pressure setting of the secondaryside. There are attached pressure guages for both theprimary and secondary sides which are extremely usefulfor checks, adjustments and other operations.Centering nozzle mounting directionMeasurement nozzledirection Centering nozzle directionRewind typeGuide roller typeWind typeMounting diagramPneumatic-hydraulic model
