Product Description
High-Precision HBr/HCl Preprocessing Online Monitoring System
The HNAG800-HBR/HCL Preprocessing Online Monitoring System is specially engineered for the continuous, real-time detection of highly corrosive Hydrogen Bromide (HBr) and Hydrogen Chloride (HCl) gas concentrations and leakages. By integrating a high-performance electrochemical sensor with advanced microcontroller technology, this system delivers an exceptionally fast response speed (T90 < 10s), high measurement accuracy (±3% F.S.), and outstanding repeatability. Utilizing an explosion-proof wiring method, the device is fully certified for hazardous locations and integrates seamlessly with user computers, PLCs, DCS, and standard control alarm systems.
Robust Stainless Steel Design & Gas Sampling Mechanism
Encased in a heavy-duty stainless steel cabinet to withstand corrosive environments, the monitoring system relies on a meticulously engineered continuous gas sampling process. The extracted HBr/HCl gas first passes through a high-efficiency filter to strictly remove dust, particulates, and impurities. A dedicated sampling pump then directs the sample into a precision flowmeter, securely maintaining the incoming gas flow rate between 0.3 and 0.5 L/Min. This regulated pretreatment guarantees that the electrochemical sensor operates under optimal conditions before the toxic gas is safely exhausted.

Industrial Applications & Flange Installation
This continuous HBr/HCl monitoring system is an essential safety and compliance component deployed widely in chemical processing plants, petroleum refineries, semiconductor manufacturing, pharmaceutical production workshops, and environmental monitoring stations. The system is designed to support standard pipeline flange installations and wall-mounted setups, ensuring secure, leak-proof sampling directly from exhaust stacks or highly corrosive process pipelines.
Customized Gas Pretreatment Configurations
To accommodate the extreme corrosiveness of HBr and HCl gases alongside complex plant conditions, multiple tailored internal configurations are available:
1.Normal to Medium Temperatures: Configurations equipped with PTFE tubing, condensation units, and timed peristaltic drainage pumps, ideal for negative-pressure pipelines and moisture-heavy extraction.
2.High-Temperature & Dusty Environments (400-800°C): Advanced systems integrating vortex flow cooling coils, dual filtration, and automatic time-relay solenoid valves for pipeline reverse-purging to prevent filter clogging from chemical dust.
3.Explosion-Proof Pneumatic Setup: Highly recommended configurations utilizing pneumatic pumps driven by plant compressed air and full stainless-steel pipelines to ensure maximum safety and prevent internal electronic corrosion.
Frequently Asked Questions (FAQ)
Q: What is the expected service life of the electrochemical HBr/HCl sensor?
A: The highly sensitive electrochemical sensor is a consumable component with a typical operational service life of approximately 1 to 3 years. The actual duration depends heavily on the specific industrial monitoring environment, background gases, and target gas exposure levels.
Q: What routine maintenance does the sampling system require?
A: You must replace the internal filter when the color of its core chip changes, which typically happens every 3 months under standard industrial testing environments. Additionally, if the unit is operating between -20°C and 60°C without an automatic drainage configuration, the water produced by the filter must be manually drained. The sampling air pump generally requires replacement after approximately one year of continuous use.
Q: How are alarm thresholds managed?
A: The standard system configuration features a two-level threshold alarm, with an optional three-level alarm structure available. When triggered, the system can activate on-site sound and light alarms, external ventilation devices via relay switches, remote controllers, and instantly notify computer data acquisition software.
