Overview
The FPI GT-TS Series is a line of explosion-proof combustible gas detection and alarm instruments engineered for continuous, reliable monitoring of flammable gas concentrations in hazardous industrial environments. Designed in strict compliance with IEC 60079-0 and IEC 60079-1 standards, the GT-TS series—specifically models GT-1030-TS and GT-1031-TS—carries Ex d IIC T6 Gb certification, permitting safe operation in Zone 1 and Zone 2 classified areas per ATEX and IECEx directives. These detectors operate on the catalytic bead (pellistor) principle: combustible gases oxidize exothermically on a heated platinum coil within a matched reference-compensated sensor pair, producing a measurable resistance change proportional to gas concentration (typically reported in %LEL). The instrument’s robust architecture supports long-term stability under variable ambient conditions, making it suitable for petrochemical plants, natural gas distribution stations, chemical storage facilities, and confined-space entry monitoring systems.
Key Features
- Explosion-proof enclosure rated Ex d IIC T6 Gb — certified for use in high-risk Class I, Division 1 / Zone 1 locations
- Imported catalytic combustion (pellistor) sensor with over-range protection circuitry to prevent sensor damage during transient high-concentration exposure
- Multi-stage anti-corrosion surface treatment (electrophoretic coating + powder coating + optional stainless-steel housing variants) ensuring durability in humid, saline, or chemically aggressive atmospheres
- Integrated temperature and concentration compensation module enabling stable measurement performance across –20 °C to +50 °C ambient operating range
- Infrared capacitive touch keypad — enables full configuration, zero calibration, and alarm reset without opening the enclosure, minimizing downtime and eliminating ignition risk during maintenance
- Built-in dual-mode alarm output: visual (high-intensity LED strobe) and audible (85 dB@1 m) with configurable latching/non-latching behavior
Sample Compatibility & Compliance
The GT-TS series is calibrated for common hydrocarbon-based combustible gases including methane (CH₄), propane (C₃H₈), hydrogen (H₂), and butane (C₄H₁₀), with cross-sensitivity profiles documented per ISO 16000-23 and EN 45544-2. Sensor response is linear within 0–100% LEL (Lower Explosive Limit) for target gases, with typical repeatability ≤±2% LEL and zero drift <±1% LEL/month under controlled lab conditions. All units comply with GB 15322.1–2019 (Chinese national standard for point-type combustible gas detectors), as well as electromagnetic compatibility requirements per GB/T 18268.1–2010 (equivalent to IEC 61326-1). Documentation packages include factory calibration certificates traceable to NIM (National Institute of Metrology, China) and optional third-party verification reports aligned with ISO/IEC 17025.
Software & Data Management
While the GT-TS operates as a standalone field device, it supports analog 4–20 mA current loop output (HART-enabled on selected variants) and RS-485 Modbus RTU communication for integration into centralized SCADA, DCS, or safety instrumented systems (SIS). Configuration is performed via local IR touch interface or remotely using FPI’s proprietary PC-based commissioning tool (GT-Config Suite v3.2), which logs all parameter changes with timestamp and operator ID—supporting basic audit trail functionality required under GLP and internal QA procedures. Firmware updates are delivered via secure USB dongle; no cloud connectivity or remote firmware-over-the-air capability is implemented, preserving air-gapped operational integrity in critical infrastructure applications.
Applications
- Continuous leak detection in compressor stations, LNG terminals, and pipeline metering skids
- Area monitoring around flare stacks, vapor recovery units, and loading/unloading berths
- Confined space pre-entry verification and real-time atmospheric supervision during maintenance operations
- Backup detection layer in SIL-1 or SIL-2 safety loops when integrated with certified logic solvers (e.g., Siemens Desigo CC, Honeywell Experion PKS)
- Compliance-driven monitoring per OSHA 1910.120 (HAZWOPER), NFPA 505, and local fire code requirements for industrial occupancy classifications
FAQ
What gases does the GT-TS detect?
The GT-TS is primarily calibrated for methane, propane, hydrogen, and butane. Cross-sensitivity data for other combustibles (e.g., ethanol, acetone) is available upon request.
Is HART communication supported on all GT-TS models?
HART capability is optional and requires specification at time of order; standard units provide only 4–20 mA analog output.
Can the GT-TS be used in outdoor installations exposed to rain or snow?
Yes—IP66-rated enclosures are standard; optional IP67 housings are available for submersion-prone or washdown environments.
Does the device meet FDA 21 CFR Part 11 requirements?
No—the GT-TS is not designed for regulated pharmaceutical or biotech process environments requiring electronic record/electronic signature compliance.
What is the recommended calibration interval?
FPI recommends bump testing before each day’s use and full span calibration every 6 months, or after exposure to poisoning agents (e.g., silicones, lead compounds) or physical shock.
