The movement of the gearwheels is measured throughthe enclosing housing wall by a sensor. The devices are suitable for viscous, fluid, self-lubricating media, as well as for aqueous fluidssuch as soaps, pasts, emulsions etc. which have a non-abrasive character. Because of the volumetric functioning principle, thedevices are almost completely independent of viscosity.A push-pull transistor output, an A/B output or a two wire output are available as signal output.The push-pull output can as desired be connected as a PNP or anNPN output, and emits a frequency proportional to the flow rate.The A/B output consists of two push-pull outputs, whose signals are phase-shifted by 90°. This makes it possible to determine thedirection of flow using the bidirectionally driven sensor. The 2-wire model represents the pulse as two different currents, and has theadvantage of reduced wiring effort.Alternatively, it is possible to use add-on electronics with signal processing, in the series OMNIPLUS, OMNI, FLEX and LABO.dsh_fam_vhz_en_vs02Supply 10 … 30 V DC voltage Current approx. 20 mA without load consumptionSignal output transistor output "push-pull" (resistant to short circuits and polarityreversal) lout = 100 mA max.2-wire Supply 4.5..24 V DC voltage Signal output low: 7 mA high: 14 mA Reverseyes polarity protected Electrical connection optional plug DIN 43650-A / ISO 4400or for round plug connector M12x1, 4-pole Ingress protectionIP 65 Weight see table "Pressure resistance and weight" Conformity CECompressive strength and weight GTypesG 1/4 G 1/4 G 3/8 G 3/8 G 3/4 G 3/4 G1VHZ-008GA VHZ-008GK VHZ-010GA VHZ-010GK VHZ-020GA VHZO-020GA VHZ-025GAPN bar 200 160 160 160 160 100 80Housing material Aluminium Stainless steel Aluminium Stainless steel AluminiumAluminium / glass AluminiumWeight kg 0.5 1.5 0.5 1.5 1.6 1.6 6.31
