The graph opposite shows the course of the pressure inside the cartridge. The pressure increases when the pneumatic valve is opened. The desired dispensing pressure is only reached reached after a delay. This delay phase has an undefined effect on the dispensing quantity. The smaller the required dispensing quantity, the shorter the pressure pulse and the pressure pulse and the greater the dosing quantity fluctuations. MUSASHI Engineering stabilises the pressure pulse by shortening the time it takes to build up pressure. (AirPulse Stabilising Circuit). This is achieved by precise pressure regulators with low hysteresis, extremely fast switching valves and an additional pressure accumulator. pressure accumulator. In this way, the time required to build up pressure can be significantly shortened and the dispensing results can also be significantly improved.

For extremely fine dispensings, the changing ratios in the cartridge also have an effect. When the cartridge is emptied, the ratio of compressible air and almost incompressible metering material changes. This changes the time of the pressure build-up.

The graph opposite shows the effects and a measure for compensation. Area A shows the pressure curve for a full cartridge. If the material volume in the cartridge decreases, the proportion of compressible air increases and thus the time to reach the dosing pressure. This delays the dispensing process process is delayed and the dosing volume is reduced for highly viscous media.

With MUSASHI's SIGMA function, the controller detects the delay until the dispensing pressure is reached and extends the dispensing pulse to compensate for the influence of the delay and stabilise the dispensing volume. delay and stabilise the dispensing quantity.
