Safety Maintenance Free Gas Detection
Flexible and easily adjusted to suit the specific requirements of different personal monitoring applications, Draeger’s (Germany) X-am gas detection instrument provides accurate, reliable measurement of 1 to 5 gases. Lightweight and as small as a mobile phone, it is completely maintenance free and ensures fast, reliable monitoring of ambient air. Rugged in design and easy to use, this innovative, ATEX approved (to zone 0) instrument also offers extremely low operational costs.
Incorporating the latest miniaturised XXS generation of high performance sensors, the X-am 5000 can be fitted with up to four sensors to detect as many as five gases at once. For example, by using a catalytic Ex-sensor together with two
electrochemical sensors and a combination, double sensor for CO and H2S, it will provide simultaneous measurement of explosive gases and vapours as well as O2 and other toxic gases.
As well as a wide range of sensors to protect against CO, H2S, CO2, Cl2, HCN, NH3, NO2, PH3 and SO2, Draeger oxygen sensors offer a five-year expected lifetime, and the catalytic Ex sensor, calibrated to methane, offers exceptional longevity. Providing improved safety when facing unknown hazards, this Ex sensor responds quickly to explosive gases (additional calibrations are available) and offers a high level of sensitivity to combustible organic vapours. As a result, it ensures dependable warnings in the event of explosive hazards.
Easy to exchange, upgrade and/or calibrate for different gases, the use of Draeger sensors also means that the instrument is suited to a wide range of personal monitoring applications, including those associated with rental equipment.
Designed for intuitive operation and featuring a practical two-key control panel and straightforward menu guidance system, the X-am 5000 features three different alarms. The audible multi-tone alarm is impossible to miss, whilst a visual 180-degree alarm helps to ensure that the warning is not ignored, as does the built-in vibrational alarm.
Dust and water resistant to IP67, this rugged instrument will even remain fully functional and ready for use after being dropped in water. The integrated rubber protection and shockproof sensors provide additional resistance to impact and vibration, and the unit is also able to withstand electromagnetic interference.
Fitted with a crocodile clip for secure attachment to clothing, the ergonomic design features gas inlets on both the top and front to ensure that, even if it is accidentally placed in a jacket pocket, it will still provide a reliable warning against gas hazards.
The X-am 5000 can be used with either the standard alkaline or optional NIMH batteries. In addition it can be fitted with a T4 battery which can be recharged in the workshop or in a vehicle, whilst still inside the instrument.
A variety of options are also available such as an external pump with flexible hose for use in pre-entry/confined space measurement applications and the Draeger E-Cal automatic test and calibration station. Designed to save time and reduce workload, the Draeger Bump Test Station is another ideal system extension. Equipped with a data logger as standard, the unit also allows data such as measured values and configurations to be transmitted via infrared interface to a PC. The data can then be analysed using the Draeger Gas Vision software, with optional user registration being carried out via the Draeger CC-Vision software.
Ion Science (UK) introduces the ATEX approved 3 wire TVOC (Total Volatile Organic Compound) monitor, for use without safety barriers in Zone 2 hazardous areas.
The ATEX certified TVOC monitor can be installed without barriers in a Zone 2 area, to directly replace an existing VOC area monitor. A significant benefit to the customer is the instrument’s easy installation; saving time and reducing costs.
TVOC is also available as an IECEx and ATEX approved 4 wire option for zone 1 areas, with safety barriers.

New Solution for the HART Communication Protocol with Entire Line of Explosion Proof Flame Detectors
The HART (Highway Addressable Remote Transducer) Protocol is the global standard for sending and receiving digital information across a 4-20 mA analogue signal between smart devices and a control/monitoring system. It is a field-proven, bi-directional communication protocol carried over the same wiring that is typically used for conventional analog instruments, with no disruption of the integrity of the 4-20mA signal and no rewiring required. Data is quickly and easily communicated between our intelligent flame detectors and practically any compatible host system. A host can be any software application, from a technician's hand-held device or laptop to a plant's process control, asset management, or safety system platform.
In addition to the inherent instrument alarm function, the HART protocol permits remote access to the configuration, diagnostics, as well as maintenance and alarm records of any networked Net Safety (Canada) flame detector. Field operators can accurately assess device conditions and prepare for routines before traveling into the field. One of the unique features of the Net Safety HART solution is an easily accessible separated input option. Most flame detectors installed in the field are mounted close to ceilings in order to effectively monitor hazardous areas. Our separated input option gives field-operators a direct, ground-level input to Net Safety flame detectors using any remote HART host device, such as a hand-held communicator or laptop.
Developed for use in a wide range of industrial applications requiring accurate explosion-proof flame detection, the entire line of Net Safety detectors support oil & gas production, refining, distribution, and storage operations as well as chemical processing, aircraft hangars, and electrostatic spray paint booths to name a few. The Net Safety UV/IR flame detector monitors both the ultraviolet (UV) and infrared (IR) spectral ranges, providing high immunity to false alarms due to lightning, arc welding, hot body objects and other sources of radiation. The UV flame detector monitors only the ultraviolet (UV) spectral range for optimised speed of response. Both the UV and UV/IR flame detectors are also available in specially tuned H2 flame detector versions which can detect invisible hydrogen and silane flame. Net Safety's Phoenix Triple Infrared flame detector delivers the ultimate safety, security and performance for any application. The Phoenix uses no external reflector for routine visual integrity checks - no other detector on the market can offer this advanced technology, which greatly reduces faults and maintenance especially in extreme applications where salt, heavy rain, sand or snow are constantly present. It has the lowest power consumption of any competitive product and is engineered to perform even in the most extreme conditions. With a full 90 degree certified field of view and extended detection ranges, field adjustable sensitivity and time delay, proprietary Automatic Digital Zone (ADZ) technology and the highest immunity possible to hot body radiation, lightning, arc welding and sunlight - the Net Safety Phoenix Triple IR is setting the new standard for industrial grade multi-spectrum IR flame detection.
