Introduction
23 patents, the only national key new product in similar instruments, inspection by national coal inspection center, the only without adjusting, testing precision of coulomb sulfur gas flow meter. Technical parameter Sulfur range: 0.01 ~ 35) % Temperature control precision: plus or minus 2.5 ℃ Sulfur resolution: 0.01% Working temperature: 1150 ℃ 900 ℃ (coal) (oil) The sample weight: (8 ~ 110 mg) The test of time: 3 ~ 6 min/sample The number of samples: 17 Power supply voltage: 220 V (- 15% - 15%), 50 hz The maximum power: 3 kw Features 1. A high degree of automation. 2. Optimization design, fine, accurate, steady effectively guarantee the test result. Original air flow stability and balance device, digital flow detection device, long-term stable gas flow in 1 + / - 0.1 L/min, gas flow visual display and real-time detection, alarm, without artificial real-time attention and adjust the air flow, greatly improve the precision, stability and reliability of test results; Using horizontal furnace, positioning accuracy directly in ultra wide constant temperature zone (90 mm) or higher, ensure complete combustion coal samples. Locating mechanism of electrolytic cell is adopted to avoid placement randomness in the process of electrolytic cell experiment, ensure uniform mixing, consistent, SO2 electrolytic completely; Widening thickening of platinum electrode electrolysis ㎡ (195 m) and instructions of electrodes (77 m ㎡), compared with the ordinary instrument, its area increased by 30% and 4 times respectively, contact area is large, integral more precise and complete; Single microcontroller hardware integration in the process of electrolysis in a timely manner, this way can be completely overcome software integration the disadvantages of easy to missing data points quickly completely; Just choose 1 or 2 kinds of BiaoMei generated by simple linear correction coefficient, no matter in high sulfur, sulfur, low-sulfur coal, can test precision.Other sulfur meter need to select 5 or more BiaoMei, generate multiple, multi-point calibration curve equation, complicated operation, test data may be distorted, especially outside the scope of the correction. 3. Save the cost. With stable performance of maintenance free air pump, don't need to replace the plastic bowl, long service life; Large capacity drying tube, effectively reduce the desiccant replacement frequency. 4. Intelligent control, simple and convenient operation. Convenient air tightness inspection, the operator only need to press with finger gently, can be done automatically. CAN bus communication technology, CAN be more than one machine control, test each other between each other; The powerful data processing, report statistics and print functions;Can be connected to the Internet, and balance.
