Consistency regulator A4430
The consistency regulator A4430 is a system for locally maintaining the operator-set value of paper pulp consistency at the outlet of pulp pools or in other local applications.
A4430 microprocessor controllers can be supplied with electric or pneumatic dilution water valves. Regulator allow you to automatically maintain the desired concentration specified by the operator.
Advantages:
- accuracy of measurements consistency is independent of flow rate, fiber length, degree of grinding, whiteness, color, and type of paper stock
- high precision consistency regulation
- alarm and water cut-off functions
- sensor does not require calibration during operation and automatically compensates for temperature and conductivity variations
- easy adjustment based on a single consistency sample
Specifications:
- Consistency measurement range 0...16%
- Pulp pressure 1.5...10 Bar
- Accuracy of maintaining set-up consistency ±0.03%
- Control signal for valve electric/pneumatic
