Xgard Gas Detectors

Crowcon is a global leader in designing and manufacturing gas detection technology and equipment. The company has been in operation for over 40 years and is consistently building upon its products. 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.

S01718 Gasmonitor Plus Universal Gas Detector Input Module by Crowcon

Gasmonitor Plus is our flexible microprocessor controlled system designed with a modular approach, so you get exactly what you want.

Used throughout the world, both on and offshore, Gasmonitor Plus provides the cost effective solution to your system requirements. Gasmonitor Plus, the gas and fire control system you can trust.

Simple to use

• Gasmonitor Plus offers flexibility whilst still providing simple operation. All the day to day functions are accessible via push buttons on the front panel.
• As well as a rolling display, indicating the channel currently monitored, each channel has a bar graph display. This unique bar graph format is ranged to indicate readings below the first alarm setting, providing an instantaneous representation of the gas concentration on every detector.
• Common alarm LEDs on the display card and individual alarms on the panel only light when a hazard or fault is detected. This means the whole rack status can be checked at a glance.

Flexible architecture

• Each channel has three levels of alarm as well as a dedicated analogue output, set as 4-20 mA as standard.
• Optional relay modules can interface to the panel to provide up to a total of 84 output relays per rack. Sixteen of these relays can be configured/voted from a combination of the three levels of alarm per channel.
• The RS232 digital interface provides connectivity with PC for configuration, monitoring and datalog upload. Each rack is uniquely addressable, making multi-drop architectures possible. This cuts down on configuration and monitoring cabling.

Ground breaking design

• Gasmonitor Plus is a microprocessor based expandable control system, which can be multiplied to offer unlimited channels and outputs.
• Its modular construction provides ultimate customisation capacity with minimal wiring.
• Gasmonitor Plus has industry standard analogue outputs, and the mechanical design is based on 19 Eurorack. This means that the Gasmonitor Plus will integrate fully with existing rack mounted protection systems on site.
• The alochrome finish and rack screening plates ensure that the Gasmonitor Plus is impervious to radio frequency interferance.

Easy maintenance

• Gasmonitor Plus has been designed with easy servicing and maintenance in mind.
• Each channel is inhibited separately so that plant safety is not compromised during maintenance checks.
• Routine calibration can be achieved from the front panel. The one man calibration feature reduces the service overhead by half.
• One universal gas card architecture controls all gas detectors. This reduces the spares holding required for Gasmonitor Plus maintenance. Each control card is fitted with its own dedicated micro-controller so it can function independently in the event of a single point failure.
