The GD10 Series

The GD10 Series has been designed with features that provide an effective response to the detection of gas hazards in a wide range of industrial environments from boiler plant rooms to offshore petrochemical installations.

These infrared gas detectors differ from all other models, because they utilize silicon based solid-state infrared sources. The complete optomechanical design and construction is so stable that an ultra fast speed of response can be achieved while providing unparalleled service life and detector stability, thus saving on maintenance and service costs.

We offer the longest combined detector and IR source warranty on the market.

• Life-safety performance approved; ATEX  & CSA
• 15 year warranty IR sources - solid state optics
• No field recalibration
• Dual skin weather protector – no filters / gauzes or sinters
• Planned maintenance with HART
• SIL 2/3 certified

GD1 Toxic Gas Laser Detector

The GD1 has been designed with features that provide an effective response to the detection of gas hazards in a wide range of industrial environments from offshore production facilities to wastewater treatment plants. At the heart of the detector is a tuneable laser diode that eliminates environmental effects from sun, rain and fog. The laser scans single absorption lines where there is no interference from other gases.

Unlike traditional methods for detecting H2S (MOS or EC cell) the GD1 needs no recalibration and can replace multiple standard detectors to cover the same risk. The complete optomechanical design and construction is so stable that an ultra fast speed of response can be achieved while providing unparalleled service life and detector stability, thus saving on maintenance and service costs.

Supplied with worldwide hazardous area approvals. Suitable for use in systems with SIL 2 requirement.

Spyglass Open Path Combustible Gas Detector

The Spyglass system detects hydrocarbon gases by analyzing the absorption of radiation caused by gases in the atmosphere and comparing it to background atmospheric absorption. This is accomplished between a pair of units: a Flash Source and a Detector that can monitor a distance of up to 200 meters.

Spyglass Gas Detectors are robustly designed and can handle the toughest environments: 316L stainless steel housings that meet IP66/IP68 and NEMA 250 6P egress standards; circuit boards epoxy coated for protection; MIL-C-810C testing for humidity, salt, fog, vibration, mechanical shock and temperature extremes; and SIL-2 approval per IEC61508 is a final statement in reliability.

• Multi-combustible gas detection
• Range of 200 meters
• Low maintenance costs
• Easy detector communication
• Easy configuration and troubleshooting
• Automatic heated optics
• Built-in event recorder
• Stainless steel construction
• Long warranty

OLCT 80/OLCT 80 Wireless

3M Gas & Flame Detection is pleased to introduce its wireless system with the OLCT 80 field detector/transmitter. This new model allows wireless connectivity in ATEX 1 zones.

Features and benefits of the OLCT 80 Wireless include:

• An infrared remote controller and on-board display for non-intrusive, one-man calibration;
• Flameproof or intrinsic-safety sensors;
• A design suitable for explosive areas;
• Low power requirements;
• Universally accepted frequency of 2.4 GHz/900MHz; and
• Flexible input/output options, including analog, TOR and Modbus RS485

Designed to meet the demanding needs of the largest industrial companies, the OLCT 80 is a major achievement in terms of technical performance and cost optimization.  Available as remote version, flameproof or intrinsic safety approved sensors depending on gases to be detected. Detects O2, combustible, toxic and refrigerant gases. Non-intrusive, one-man calibration.

Introducing the OLCT 60, a new generation of high quality gas detectors which covers all industrial needs for a variety of applications.

The OLCT 60 Series is composed of several versions:

• XP or IS sensor (toxic or oxygen versions)
• Remote or on-board sensor.

The OLCT 60AD version allows the sensor to be installed remotely up to 15 meters (standard), allowing detection in inaccessible locations, or in Zone 0 in the case of the intrinsically safe (IS) version. The detector units are made of 316L stainless steel, and are rugged and resistant to corrosion. Pre-calibrated sensors can be disconnected by turning the head of the unit. These “smart” sensors can be calibrated outside hazardous areas.

The OLCT 60 is equipped with non-intrusive access to a safe menu. In hazardous areas, calibration can be done with an operating mode in accordance with safety rules.

• Access to maintenance menu
• Pure air injection
• Zero validation*
• Standard gas injection
• Calibration validation taking into account the usage rate*

All of these tasks can be carried out without opening the detector, using a unique magnetic key. Access to the maintenance mode is protected to avoid accidental reprogramming of the unit.
