SKU: ERANNTEX Online Hydrogen Sulfide Detection Alarm
Introduction to Online Hydrogen Sulfide Detection Alarm:
Online Hydrogen Sulfide Detection Alarm are devices designed to continuously monitor hydrogen sulfide gas concentrations in the environment and issue alarm signals when levels exceed safety thresholds. They are widely used in petroleum, chemical, environmental protection, and other industries where hydrogen sulfide gas leakage risks exist.
Common online hydrogen sulfide detectors operate on electrochemical detection principles. They utilize the electrochemical reaction of hydrogen sulfide gas on electrodes to convert gas concentration into electrical signals. By measuring and processing these signals, the device determines the hydrogen sulfide concentration value. Additionally, some instruments employ principles such as ultraviolet differential absorption spectroscopy.
Features of Online Hydrogen Sulfide Detection Alarm:
β Intrinsically safe circuit design with explosion-proof certification. Features dual-level lightning and static protection exceeding national standards, withstanding high-intensity pulse surge currents. High reliability and stability. Reverse-connection protection ensures no damage from any form of incorrect wiring.
β Complies with EMI/EMC standards, passing national testing and CMC metrological instrument certification.
Implemented Standards: GB15322.1-2003
GB 3836.1—2010 “Electrical Apparatus for Explosive Gas Atmospheres - General Requirements”
GB 3836.2—2010 “Electrical Apparatus for Explosive Gas Atmospheres - Flameproof Enclosures ‘d’”
GB 3836.4—2010 “Electrical Equipment for Explosive Gas Atmospheres - Intrinsically Safe Type ‘i’”
β Simultaneous output of standard RS485 bus (RTU) and 4-20mA standard signal, 3 sets of relay switch outputs, on-site audible and visual alarms. Optional frequency output 200-1000Hz, Hart protocol signal, 1-5V output, wireless transmission (2-5 km or unlimited distance). Supports wired or wireless remote real-time monitoring, uploading data to mobile devices or transmitting via LAN/Internet to environmental protection bureaus, monitoring centers, monitoring equipment, or monitoring computers. Real-time on-site concentration monitoring via free PC software or gas alarm controllers.
β Compatible with various secondary meters, data acquisition modules, PLCs, and DCS systems. Directly drives solenoid valves, fans, alarms, etc., or drives high-power equipment via intermediate relays. Optional MIC2000 controller supports simultaneous monitoring of 1000 detectors.
β Large-capacity data storage records real-time concentration values, temperature/humidity, or only alarm values and timestamps. Supports local storage or SD card storage. Local storage has a standard capacity of 100,000 records; specify larger capacity when ordering. SD card storage capacity is customizable. Data export and analysis are performed via free PC software. Data can be viewed or deleted locally. Settings include automatic data overwriting or non-overwriting when capacity is insufficient, and automatic recording stop functionality.
β Standard infrared remote control enables operation without opening the housing in hazardous environments. Functions include: alarm point adjustment, concentration calibration, zero calibration, alarm silencing, factory reset, menu access, data review, 4mA output, and 20mA output (required for calibrating other data acquisition devices).
β Selectable Chinese/English interface (default Chinese). Supports free switching of gas concentration units. No molecular weight input required for common gases; special gases automatically calculate and switch units upon input. Available units: PPM, mg/m³, Vol%, LEL%, PPHM, ppb, mg/L.
β 2.5-inch high-definition color display (LCM) shows real-time concentration, time, temperature, humidity, storage status, etc. Simultaneously monitors 1-6 gas concentrations plus temperature/humidity. Menu interface uses high-definition simulated icons to display function names with clear Chinese or English prompts.
β Three display modes switchable: Simultaneous multi-gas concentration display, large-font cyclic single-channel gas concentration display, real-time curve display. Automatic or manual channel cycling available. Configurable to show max/min values, gas names, and historical curve graphs.
β Automatic zero tracking prevents drift. Features temperature compensation and multi-level calibration, simultaneously compliant with national standards and regional/provincial metrology bureau requirements.
β Data recovery function. Automatically identifies and prevents incorrect concentration calibration operations, avoiding adverse effects from improper handling.
β Records calibration logs, maintenance logs, and troubleshooting measures. Includes sensor lifespan expiration alerts and next concentration calibration reminder functionality.
