Online oxygen content analyzer manufacturer
Brief description:
Especially during the hydrogenation process, vacuuming and nitrogen replacement must be strictly repeated to fully ensure that the kettle is in an anaerobic state, and the oxygen content must be controlled within 1%VOL; higher requirements are placed on the service life, accuracy, error and response time of the sensor.
The nitrogen filling protection of the reactor is roughly the same as that of the centrifuge; especially during the hydrogenation process, vacuuming and nitrogen replacement must be strictly repeated to fully ensure that the reactor is in an anaerobic state, and the oxygen content must be controlled within 1%VOL; higher requirements are placed on the service life, accuracy, error and response time of the sensor.
Since it is impossible to ensure that the nitrogen meets the qualified supply input, the traditional continuous nitrogen replacement also has the possibility of explosion.
In response to the above situation, our company adopts pre-stage sampling pretreatment + on-site numerical display + automatic nitrogen filling, and can also be transmitted to DCS/GDS through 4-20mA signal according to supporting needs to achieve overall automatic chain control.
Product features:
1. Customized pretreatment: acid-base neutralization, organic matter removal, water removal, drying, voltage stabilization, constant current, etc. of sample gas.
2. Safety: When the oxygen concentration value exceeds the preset alarm value of the first level, the electromagnetic nitrogen filling and replacement will be automatically turned on until the value drops to a safe range.
3. Nitrogen flow control: Equipped with a nitrogen control box, it automatically cuts off the large flow when the oxygen concentration value is within the safe range to achieve continuous supply of small flow, meeting the micro-positive pressure in the kettle.
4. Applicable explosion-proof areas: intrinsically safe explosion-proof composite instrument, meeting the requirements of harsh use areas.
5. Signal acquisition: 16-bit ADC digital-to-analog conversion, meeting the requirements of trace oxygen data acquisition, with higher accuracy.
6. Module platform: The pretreatment level and function can be freely adjusted according to the actual use situation, and the adaptability range is wider.
7. Easy maintenance: one-key calibration/calibration, tool-free disassembly and maintenance, hot-swap replacement of sensor components.
8. Intelligent display: self-luminous OLED Display screen, multi-angle observation.
