сульфитация обнаружения и управления системой

Sulfur dioxide also is an Indispensable Chemical in Cane Sugar Processing, which is a good clarifying and decoloring agent. Rational and well controlled use of sulfur dioxide is key to upgrade the cane sugar production. The sulfitation detect and control system can detect and control sulfitation density on line in the sugar process adopting the Sulfitation Process. Its design features as integrating advanced sulfitation detecting module and sensor data processing. The detecting module simulates manual titrations, automatically samples and detects with electrodes then feeds the information to the computer. After computing the density of sulfitation the system automatically adjusts the sulfur dioxide valve, with manual adjusting the sulfur burner, the sulfur dioxide is effectively controlled. 1Computer of sulfitation detect and control system 2Sulfitation densitymeasuring device 3Sulfitation executing machanism 4Sulfitation density remote display terminal 5Electrode washing box Technical parameter Measuring range: 0.5 50Ml Current signal output: 4 20mA.DC Measurment error:≤ ±1.5mL(Sulfitated and neutralized juice) ≤ ±0.5mL(Clarified juice and syrup) Host show: 8 Inch true clolor LCD Measurement cycle: ≥3 Min(Adjustable) Measuring temperature:0 85°C Scale stepping control vale openning:0 99.9% Means of communication:CAN2.0,RS485 This system features 1 Advanced module of sulfitation measuring and technology of sensor data information,make sure the systemat a high detect and control accuracy. 2.
