System composition:
Application areas:
1.Enclosed centrifuge nitrogen filling protection system;
2.Nitrogen filling protection in various process processes;
3.Nitrogen filling protection system for storage tanks;
Product features:
1.Customized pretreatment: backflush, acid-base neutralization, organic matter removal, dewatering, cooling, drying, voltage stabilization, constant current, etc. of sample gas.
2.Safety: When the oxygen concentration value exceeds the first-level preset alarm value, the electromagnetic adjustment of nitrogen filling and replacement is automatically turned on until the value drops to a safe range; when it exceeds the second-level preset alarm value, the power supply is automatically cut off to stop the centrifuge.
3.Applicable explosion-proof areas: intrinsically safe explosion-proof composite instruments, meeting the requirements of strict use areas.
4.Nitrogen flow control: Equipped with a nitrogen control box, when the oxygen concentration value is within the safe range, it automatically cuts off the large flow of nitrogen to achieve a small flow of continuous supply to meet the micro-positive pressure in the centrifuge.
5.Module platform: The number of pretreatment levels and functions can be freely adjusted according to actual usage. Wider adaptability.
6.Easy maintenance: one-button calibration/calibration, tool-free disassembly and maintenance, hot-swap replacement of sensor components.
7.Intelligent display: self-luminous OLED display, multi-angle observation.
