In the papermaking process, pulp is fed into the headbox of the paper machine. In the hydraulic headbox, pulp enters the weir pool via the conical distribution pipe and tube bundles, and is then sprayed onto the forming wire by the weir plate. Since the pulp jet velocity is controlled by adjusting the headbox slice pressure per the wire speed, accurate pressure measurement in the headbox is essential.
Contact Engineer1. The headbox necessitates precise slurry flow rate and pressure management to achieve consistent distribution of paper quality.
2. Solid particles and fibers in the slurry might cause clogging and abrasion, reducing flow measurement accuracy.
3. The corrosive headbox slurry necessitates strong material corrosion resistance.
4. Environmental variables can have an impact on measurement stability and reliability in the headbox site.
1. With high-accuracy sensors and fast response capabilities, it can monitor the flow and pressure of the slurry in real time to ensure uniform distribution of the slurry.
2. Anti-clogging construction, self-cleaning function, and wear-resistant materials ensure stable measurement under non-homogeneous slurry conditions.
3. Corrosion-resistant materials (such as stainless steel, Hastelloy, etc.) and special coatings can extend the service life of the equipment.
4. High-stability materials and compensation tech can still provide reliable measurements even under different conditions.

On March 9th, 2009, Micro Sensor held the fourth session of the fifth board meeting. CEO Mr. Zhao Furong made a speech about the work report in 2008 to all the directors.The meeting highly appreciated the work that Micro Sensor has done in 2008, and praised all the staff for the great efforts in the last whole year. It is expected that all the staff continue to develop team-work and devotion spirits, and further improve product quality, to meet the challenges together that the global financial crisis is going to bring us in 2009.e
