GT3000 Toxic Gas Detector

The Det-Tronics GT3000 line of electrochemical fixed-point toxic-gas detectors is designed and engineered to provide continuous monitoring of the atmosphere for potentially hazardous toxic gas leaks or oxygen depletion. Both explosion-proof and intrinsically safe models are available.

The GT3000 family currently includes sensors that detect each of the following gases in various concentration levels: 

• hydrogen sulfide (H2S) - certified SIL 2 capable
• hydrogen (H2)
• oxygen (O2) - certified SIL 2 capable
• carbon monoxide (CO)
• nitrogen dioxide (NO2)
• ammonia (NH3)
• chlorine (Cl2)
• sulfur dioxide (SO2)

A complete GT3000 detector consists of a transmitter (GTX) and a sensor module (GTS). The transmitter generates a 4-20 mA output signal with HART that is proportional to the concentration of the target gas and corresponds directly to 0-100% full-scale output.

In addition to being compatible with the FlexVu® Universal Display, the GT3000 is approved as a stand-alone unit and supports local calibration without the FlexVu display.

Features

• Hot-swappable IS sensor module for live maintenance without declassification of hazardous areas
• Hydrophobic filter easily replaced without opening the device or use of tools
• Suitable for outdoor applications requiring an IP66 rating
• Magnetic switch and LEDs for user interface - also can use HART devices and FlexVu® Universal Displays for UI
• Event and calibration logs are stored in non-volatile memory

Technical Specifications

• Two-wire, loop-powered device for fault tolerance
• EMI/RFI hardened (when specific model selected)
• Electrochemical sensor cell for increased accuracy, stability and reliability
• Sensor factory calibrated to specific gas type and target concentration level
• Maximum loop resistance of 300 ohms at 18 Vdc, 600 ohms at 24 Vdc
• 316 stainless steel transmitter enclosure
