Is the Lower Explosive Limit (LEL) the same as the alarm setpoint?

No. LEL is the minimum concentration at which a gas can ignite; for methane it is about 5% by volume, which equals 100% LEL on the detector scale. Alarm setpoints are set well below it, typically at or below 25% LEL for the first-level alarm, according to the local code that governs the project.

Where should a household combustible gas detector be installed?

Mount according to gas density: for natural gas (methane, lighter than air) install high, close to the ceiling; for LPG (heavier than air) install low, close to the floor. Keep the detector within a few metres of the appliance and away from extractor hoods, steam and direct airflow.

Why do oxygen detectors use %VOL instead of ppm?

Normal air contains about 20.9% oxygen by volume, so oxygen deficiency and enrichment are tracked as volume percentages. Common reference alarm points are 19.5% VOL for deficiency and 23.5% VOL for enrichment, which are far easier to read and configure in %VOL than in hundreds of thousands of ppm.

Can a Shield gas detector shut off the gas supply automatically?

Yes. Shield household detectors drive a solenoid valve when the alarm setpoint is reached, and the JYFJS-011 emergency shut-off valve can be triggered by gas alarm systems, fire-protection panels or smart terminals. The valve must be reopened manually so gas cannot return before the hazard is cleared.

What is the difference between a stand-alone and a bus-type point gas detector?

A stand-alone detector such as the SD2130 series alarms locally and drives linkage outputs without a controller, ideal for single zones. Bus or branch-line detectors such as the SD2100A series report to a gas alarm controller (SD8001A/B) installed in a non-hazardous control room for centralized multi-point monitoring.

Does Shield offer OEM and ODM gas detectors?

Yes. With 80+ marketable product models and in-house R&D, Shield supports private labelling, housing and packaging customization and configuration changes for distributors and brand owners. Request the catalog to review available platforms.

Industrial Combustible Gas Detection: Belgian Ecosystem vs. Global Trajectory

Navigating complex regulatory pressures under ATEX Directive 2014/34/EU and Belgium's evolving low-carbon transition matrix.

Belgium's Chemical Epicenter

The Port of Antwerp-Bruges hosts Europe's largest integrated chemical cluster. The localized transition toward green hydrogen carriers (ammonia, methanol) alongside legacy ethylene and methane cracking mandates rugged point-type gas detectors equipped with optical NDIR and poison-resistant catalytic sensors.

Global Safety Paradigm Shifts

Globally, industrial point gas detection is evolving from passive threshold alarming to predictive telemetry. Modern installations require sub-10-second response profiles (T90 < 10s), integrated HART/RS-485 protocols, and proactive sensor poison diagnostics to mitigate catastrophic downtime in heavy refining.

Strict Belgian Regional Compliance

Compliance across Flanders and Wallonia demands adherence to regional VLAREM II environmental statutes alongside federal Belgian General Regulations for Electrical Installations (RGIE/AREI). Point-type combustible units must deliver verifiable ATEX Zone 1/21 explosion-proof integrity.

Tailored point-type gas monitoring architectures engineered for high-consequence operating environments.

Antwerp Petrochemical Refining & Cracking

Continuous monitoring of volatile hydrocarbon gas leaks (Methane, Ethane, Propane) along high-pressure compressor stations and flange connections. Point detectors interface directly with localized emergency depressurization and deluge actuation systems via galvanically isolated 4-20mA loops.

North Sea Green Hydrogen Corridors (Zeebrugge)

Electrolysis terminals and LNG bunkering facilities require ultra-responsive LEL detection. Our specialized point-type hydrogen detectors resist thermal drift and offer poison-immune sensor matrices capable of reliably tracking sub-second H₂ accumulation without false alarming.

Frequently Asked Questions: Point Gas Detection & Compliance

In-depth technical answers addressing engineering layout, calibration protocols, and Belgian ATEX integration.

Q1 What distinguishes a point-type combustible gas detector from an open-path beam system?

Point-type detectors sample atmospheric gas concentration at one discrete physical location via diffusion through a sintered flame-arresting mesh. They are optimal for enclosed process spaces, flange perimeters, and boiler chambers where gas gathers locally, unlike open-path systems designed for broad fence-line outdoor monitoring.

Q2 How does Belgian ATEX classification determine detector placement?

Under Belgian RGIE/AREI and European ATEX 1999/92/EC directives, areas are segregated into Zone 0, Zone 1, and Zone 2. Point-type combustible gas detectors deployed in Zone 1 environments must feature flameproof (Ex d) or intrinsic safety (Ex ia) engineering. Detectors must be situated based on relative vapor density: near the roof for methane (0.55 relative density) and floor level for propane/LPG (1.52).

Q3 What is the standard calibration interval for catalytic bead versus NDIR point sensors?

Catalytic bead sensors typically demand bump testing every 90 days and full zero/span calibration every 180 days due to potential poisoning by silicones, lead, or sulfur compounds. Infrared (NDIR) point detectors, being immune to chemical inhibitors, comfortably operate on 12-to-24-month calibration cycles under normal operating environments.

Q4 Can Chinese factory point detectors integrate with legacy Honeywell, Dräger, or Emerson DCS in Belgium?

Yes. Our point-type transmitters utilize unencrypted, standardized 4-20mA current loops with standard fault states (e.g., 2mA fault, 4mA clean zero, 20mA full-scale LEL) alongside open standard Modbus RTU (RS-485). They easily map into any major DCS or PLC platform without proprietary handshake gateways.
