Bürkert Dosing Head and Electronics for Precise Time-pressure Dosing

Type 5120 offers a standardised solution for liquid dosing in an open control loop based on the time-pressure dosing principle. The core components of this system include dosing electronics with communication gateway and a dosing head with dosing needles. Precisely controlling the dosing time with a resolution of less than 0.1 ms achieves remarkable accuracy, especially with small liquid volumes in the μl range. This solution is characterised by its compact footprint and easy installation, and can be seamlessly integrated into various pressure-time dosing applications. Compared to closed control loops, the dosing system often proves to be a more cost-effective choice when immediate feedback on the dosing volume is not required. Type 5120 is an integral system platform in which both the control and the fluidics can be easily customised and expanded. The comprehensively coordinated dosing ecosystem can be conveniently sourced from a single supplier.
