As an example, typical drivingparameters are listed below to give a general orientation for testing. The parameters have been obtainedusing the mp-x controller with the SRS signal preset. Please refer to chapter 5 for operation of the mp-xcontroller.Target flow rate Amplitude Frequency Target flow rate Amplitude Frequency7 ml/min 250 V 100-110 Hz 2 ml/min 220-240 V 20 Hz6 ml/min 250 V 80-9 0Hz 1 ml/min 125-135 V 20 Hz5 ml/min 250 V 55-65 Hz 0,5 ml/min 90-100 V 15 Hz4 ml/min 250 V 40-50 Hz 0,25 ml/min 85-95 V 8 Hz3 ml/min 250 V 30-35 Hz 0,1 ml/min 80-90 V 3 HzAs a general guideline the amplitude should be kept as high as possible while varying the frequency.4.3.1.2 Medium: airDriving the micropump with the controller mp-x at 300 Hz with 250 V, flow rates of 18 ml/min andbackpressures of up to 100 mbar have been achieved.In general, for driving the pump with air, higher frequencies should be used than for water. To minimizeaudible noise, using the sine signal is recommended. As this is preliminary data, please contact us for moreinformation when you intend to use the pump with air.4.3.2 mp6-pp4.3.2.1 Medium: Dl waterThe flow curves present typical flow data, results may differ under varying operation conditions.
