pH Auto-Controller

pH Auto controller also named pH auto control system is widely applied in the sugar industry, ours special designed double glass electrode measuring device make sure this system actually on line controlling and measuring to sugar juice with serious scale condition, with continuously and non-interference working. And special designed step control mechanism, high accuracy to step controlling milk of lime, make sure the pH value in fine status. This auto controller is compose of as follows, showed as the photograph: 1Main computer 2Double glass electrode measuring device 3Step control mechanism (auto control milk of lime flowing) 4pH detecting meter5Single glass electrode measuring device 6Cooling device System technical parameter: Ph value measuring range:0.00pH 14.00Ph Display resolution:0.01Ph Input current: lower than 5fA(25°C) Means of communication: RS485+GSM or CAN2.0 Control range of pH Vulue: 5 12pH Matching error: ≤±0.1pH±character Online control accuracy: ≤±0.15Ph Cane juice temperature range: 5 70°C Automatic terperature compensation:0 100°C Isolated current signal output: 4 20mA.DC Operate mode: continuous Basis error:0.02 Ph ≤±1character This system features: 1. Enhanced pH electrode signal processing, ensuring more the integrity of pH electrode signal. 2. Double-embedded CPU, parallel data processing technology, with faster processing speed and real time. 3. With 8-inch large color LCD, super wide vision,rich and colorful display. 4. Electrode movement of detecting and control function are interlocked, preventing misoperation. 5. The step control mechanism realizes maintenance-free design, the anti-break-down function is more perfect. 6. The system can store data of production for 15 days, facilitating user(s) to analysis production condition, historical data and real time data curve are shown. 7. Software of the pH control is diversified and intelligenized, more adaptable to application sites with better control effect.
