By integrating modern technology with the demands of the modern workplace, Crowcon has developed a line of gas detection devices and monitors that lead the competition. The Xgard range of gas detectors is a product of Crowcon s successful integration and technological advancements. With a wide range of sensor types and available accessories, the Xgard series is suitable for all worksites and is customizable enough to fit any needs.

Tough and reliable

The Xgard series of fixed point gas detectors is incredibly durable and reliable. The casings and materials, including weatherproof caps, are designed to protect the equipment from the harshest environments. The detectors are made from a variety of materials depending on the model: glass reinforced nylon, aluminum with polyester coating, and 316 stainless steel.

Variety of sensors

The fixed point gas detector offers a wide range of sensors for to suite almost all applications. The Xgard range of gas detectors is available in three models to meet varying worksite needs: flameproof, intrinsically safe, and safe area formats. Additionally, Xgard offers different types of fixed point gas detectors within these three models:

• Xgard Type 1- Intrinsically safe toxic and oxygen gas detectors
• Xgard Type 2- Flameproof toxic and oxygen gas detectors
• Xgard Type 3- Flameproof flammable gas detector
• Xgard Type 4- Flameproof high temperature flammable gas detector
• Xgard Type 5- Flameproof flammable gas detector with 4-20mA output
• Xgard Type 6- Flameproof thermal conductivity type gas detector
• Xsafe- Safe area flammable gas detector

Cost efficient and highly effective

With quick and easy installation and maintenance, the Xgard series is able to keep costs at a minimum. The replacement sensors, for example, are simple to replace by merely plugging them in. The replacement parts are also readily available and compatible with all Xgard models, thereby reducing the amount of required spare parts that are stored in the facility. Additionally, the sensors have two times the typical life spans of similar sensors in the industry. With a 2 year life span, worksites can expect to cut their sensor replacement costs in half. For worksites that require slightly more customization, Crowcon offers compatible accessories for the Xgard series such as sampling applications, remote gassing applications, spray deflectors, sun shields, weatherproof caps, collector cones, flow adapter, and accessories adapter.

Xgard also has flexible installation options. The unit is designed for either wall or ceiling mounts, and users will not need to purchase additional equipment for mounting. For more complex installation needs, users can purchase accessories.

Specifications

Each model is approximately the same size with dimensions of 6.1 x 6.5 x 4.3 inches and weighing approximately 1 or 2 pounds. The battery type, electrical output, and power requirements vary based on the sensor type.

61-0140RK Sensor, LEL Combustible (Catalytic), Direct Connection (No Transmitter, No J-Box), UL Version by RKI Instruments

When working on potentially hazardous jobsites, safety managers should look for workplace safety solutions that are dependable and steadfast. When lives are on the line, a workplace cannot afford subpar safety products. That is why, at RKI Instruments, workplace safety is a top priority. Their Research and Development team work daily to integrate the latest technology with the best industry practices. With a reputation for excellent products, RKI Instruments introduces the latest in direct connect sensor technology. Designed for use in Class 1, Division 2 hazardous environments, the Direct Connect Sensors are designed specifically for RKI Beacon 110, 200, and 410 controllers.

Direct Connect Sensors

The RKI Direct Connect Sensors series gas sensors are state of the art gas detection sensors available for LEL, H2 Specific LEL, LEL IR, Oxygen, H2S, CO, CO2, and a variety of toxic gases. To use the Direct Connect Sensors, they can be used for remote detection by mounting them onto explosion proof junction boxes, or they can mount directly onto controllers and be used as a completely standalone system. Their unique plugin design allows for a quick and easy tool free installation on jobsites.

Detection solutions for a variety of hazardous environments

The Direct Connect Sensors are designed to be use in both indoor and outdoor settings. Additionally, some of the sensors are available in explosion proof models. The explosion proof models utilize a patented coating which serves double duty as also being water repellant. Users can also purchase splash guards to protect the sensors from very wet conditions.

Sensor Technology

Each sensor is crafted with stainless steel and housed in cast aluminum (stainless steel housing is available for some sensors). The Direct Connect Sensors are available in 2 forms: explosion proof and non-explosion proof. The explosion proof sensors are available as catalytic sensors for LEL, and LEL H2 specific. For hydrogen sulfide and carbon monoxide, the sensors utilize electrochemical technology which provides incredibly specific accuracy and quick response. Oxygen sensors work with galvanic technology, and infrared sensors for methane, hydrocarbons, and carbon dioxide. Non-explosion proof uses a galvanic sensor for oxygen; electrochemical sensors for hydrogen sulfide, carbon monoxide and other toxic gases; and infrared for carbon dioxide. Both explosion proof and non-explosion proof have 1 year warranties for materials and craftsmanship.

Specifications

The response times are under 30 seconds for all gases except hydrogen sulfide and carbon monoxide in the non-explosion versions (with a response time of 35 seconds) and non-explosion proof model sensor for toxic gases which has a 60 second response time. The life expectancy of all sensors are between 2 and 5 years.

The Direct Connect Sensors are compatible with several RKI Industries' accessories including calibration adaptors, flow through adaptors, remote horns and lights, calibration kits, battery backups, splash guards, air aspirator adaptors, and dataloggers.
