Product Description

Reactor nitrogen protection monitoring system

Brief description: 
1. The nitrogen protection monitoring system of the reactor must be strictly and repeatedly vacuumed and replaced with nitrogen to fully ensure that the reactor
is in an anaerobic state, and the oxygen content must be controlled within 1%VOL;
2. higher requirements are placed on the service life, accuracy, error and response time of the sensor.
3. 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.
4. In view of 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

specific functions:
1. Used in pesticide, chemical, pharmaceutical, food and other industries.
2. Sampling processing - gas analysis - a complete solution for the entire process of automatic linkage.
3. The supporting pretreatment system can perform dust removal, acid removal and other treatments to remove the corrosion of alcohol and benzene organic substances to the instrument.
4. When the oxygen content exceeds the preset alarm setting value, various functions such as automatic alarm, nitrogen filling replacement, power-off protection, etc. can be realized according to needs.
