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.

Oxygen Detector CTX 300

• Detects O2, CO2, toxic and refrigerant gases
• 4-20 mA output analog transmitter with optional backlit display
• Plug-in and pre-calibrated sensors
• Available with electrochemical, infrared or semi-conductor sensors
• More than 30 different sensors are available to detect most toxic gases in the industry
• Available in an infrared version for CO2
• EN14624 compliant with regards to R134a monitoring
• Oxygen detector for commercial or industrial applications in unclassified areas

When hazardous levels of toxic gases or oxygen threaten the safety of an unclassified area, the CTX 300 oxygen detector can satisfy the most demanding safety requirements.

The CTX 300 detector is designed to detect oxygen, toxic and refrigerant gases, and also uses a new sensor for CO2 detection over three different ranges: 0-5000 ppm, 0-5% vol. and 0-100% vol.

The CTX 300 transmits data in record time. With a wide range of sensor options, it has the flexibility to protect many potentially hazardous environments.

Maintaining the unit is easy with pre-calibrated sensors and an optional LCD display.
