3 Application The cartridge ZHM is suitable to handle base paints, fillers, transparent and water-born coatings perfectly. It may also be used for wax and adhesives. The standard version has a carrierfrequency pulse amplifier which will precisely detect the r.p.m. of the gears. This happens without contact with the measuring medium and free of drag. The amplifier provides a digital output signal with a frequency directly proportional with the flow volume. For applications in electrostatic spraying systems the fibre-optic amplifier FOP 60 is available. The fibre-optic principle guarantees for an interference-free signal transmission. All pickups are available with IS-approval for use in hazardous areas. Typical Applications Base paints, fillers, transparent and water-born coatings Wax and adhesives Specials High resolutiony Low weight Interference-free signal transmission Ex-protected Applicable in electrostatic spraying systems Principle and Design This ZHM series excels in numerous models for various applications: e. g., paint versions with flat seals and single-ended shafts for an ideal purging quality. In addition, versions with special bearings are available for critical paints. As an option adapter plates can be supplied (see left picture below). The cartridge design of this follow-up model reduces the weight by another %. Therefore, the Cartridge-ZHM may be installed right behind the spray gun without adverse effects on the dynamic properties of the spray robot. The newly designed measuring kit provides a high resolution and allows for a precise measurement over a measuring range which would usually require two flow meters. The new flow meter can be completely purged within a few seconds and rapid colour changes are possible with no adverse effects on paints by residual sediments. Pickups and Amplifiers The integral carrier-frequency pulse amplifier type VTE.CT or fibreoptic amplifer type FOP 60 allow for space-saving installation. A legal protection of registered designs for the Cartridge-ZHM has been applied for. 3
