WD6200IR Infrared Gas Detector
Double-beam infrared combustible gas detection with local diagnostics and 4-20mA/HART or RS485-RTU interface configurations for GTYQ-WD6200IRII.
Gas Detection
Product selection can be reviewed by installation environment, gas type and target-market requirements.
Product Overview
The GTYQ-WD6200IRII configuration uses double-beam infrared sensing for fixed combustible gas monitoring in refineries, LPG/LNG facilities and gas plants. Its LCD shows gas concentration and device diagnostics, while 4-20mA/HART and two programmable relays connect measurement, alarm and fault information to compatible systems. Calibration and overdue indications support maintenance planning. The baseline specifications below cover GTYQ-WD6200IRII. Additional range and interface configurations are listed separately and require confirmation against the complete model suffix, including II or PRO, before ordering.
Product category
Gas Detection
Industrial fixed monitoring points, station areas, commercial facilities and selected combustible gas risk locations.
LCD concentration display and device diagnostics
4-20mA/HART or RS485-RTU interface configurations, selected to match the control system
Calibration and overdue indications for maintenance follow-up
Magnetic-bar and infrared-remote operation; optional Bluetooth
Application Fit & Installation Boundary
Select products for the installation environment, gas type and system role.
Application fit
GTYQ-WD6200IRII fits fixed combustible gas monitoring at petrochemical plants, refineries and LPG/LNG facilities where local diagnostics and connection to a control system are required.
Installation context
The detector should be positioned near potential leak points after confirming gas type, mounting height, ventilation and site conditions.
Selection boundary
Select the II configuration for the required combustible gas; do not assume it measures every gas or includes PRO features. Confirm hazardous-area certification coverage, calibration requirements and system compatibility for the target market.
Typical Applications
Common gas safety scenarios where this product category can support monitoring, alarm verification or response workflows.
Industrial combustible gas monitoring
Gas station or regulating station risk points
Commercial gas facility safety projects

FAQ
Common questions for early product selection and project discussion.
Which WD6200IR version do these specifications cover?
They describe GTYQ-WD6200IRII. Confirm the complete model suffix before ordering; the II specification must not be assumed to cover a PRO version.
How does the detector support maintenance?
The LCD provides diagnostic information and calibration reminders. These aids do not replace inspection, calibration or functional verification under the applicable maintenance procedure.
What information is needed for system integration?
Provide the target gas, controller input, relay loads and installation conditions. Select the 4-20mA with RS485-RTU configuration or the 4-20mA/HART configuration, then confirm wiring and protocol documentation. Optional Bluetooth and relay arrangements must match the selected version.
Are certifications available?
