Dräger X-zone 5000 Confined Space Monitoring Without Limits

Area monitoring without limits – the Dräger X-zone 5000. In combination with the Dräger X-am 5000, the X-zone 5000 reliably monitors for up to six hazardous gases and warns at preset levels.This easily transportable, robust and water-proof unit extends mobile gas detection technology to a unique system with many applications.
INNOVATIVE AREA MONITORING
The Dräger X-zone 5000 transforms the Dräger X-am 5000 personal gas detection instrument into an innovative area monitoring device for a wide range of applications. A patented combination for increased safety – used with personal gas air monitoring carried on the body or positioned where gas hazards are expected, the X-zone 5000 area monitor knows no limits!

CLEAR ALARM - 360°
Even from a distance, the illuminated green LED ring indicates that the air is free of toxic and combustible gases. When gas hazards are detected, the LED changes colors from green to red, providing a clear visual warning that hazardous gas is present. In addition, it emits a loud and audible evacuation alarm. With a patented 360° alarm amplifier, the acoustic warning is heard easily over a wide area, independent of wind direction. The Dräger X-zone 5000 gas entry is arranged so that gas can diffuse into the Dräger X-am 5000 from all sides.

WIRELESS FENCELINE
Up to 25 Dräger X-zones can be automatically interconnected to form a wireless fenceline. This interconnection of the monitoring devices allow for rapid securing of larger area, e.g. leaking pipelines or industrial tanks - or the monitoring required during industrial shutdowns.

In the event of a gas alarm, the Dräger X-zone 5000 transmits alarm signals to all units that are part of the fenceline which then display a daughter alarm. The original alarming unit shows a red LED along with its audible alarm, while the daughter alarm displays green/red with its illuminated LED ring. This provides fast, easy recognition of the general alarm, while identifying the unit which alarmed originally. This assures a positive alert and a clear and clean evacuation. Alternatively, the fenceline can be wired.

AREA MONITORING – USING A SAMPLING PUMP
An optional integrated pump allows monitoring of remote areas by pulling a sample to the device. This provides continuous monitoring of confined spaces and locations which are difficult to access – from a distance of up to 45 m (150 ft).

ALARM CONTACT FOR CONNECTION TO EXTERNAL EQUIPMENT
Via the potential-free alarm contact, the Dräger X-zone 5000 device can be connected to and operate external equipment such as alarm horns, lamps or traffic lights. In addition, the fenceline signal, along with the alarm contact, can be forwarded to a control room – overseeing a wide range of applications.

AVAILABLE FOR USE IN CLASS I, DIV 1 OR ZONE 0 AREAS
Unlike personal gas detectors, area monitoring devices often stay located within a potentially hazardous area, even during a gas alarm. It is therefore important that the devices are approved for use in explosive hazard areas. The approvals for X-zone 5000 enable the continuous operation of the device in an explosive atmosphere and environment.

CONTINUOUS OPERATION FOR UP TO 120 HOURS
Two different types of rechargeable batteries enable the Dräger X-zone 5000 to be adapted to a variety of applications: the 12 Ah battery unit weighs about 7kg (15 lbs) and offers continuous operation for up to 60 hours. The alternative 24 Ah battery provides up to 120 hours of continuous operation – a complete working week.

INDUCTIVE CHARGING TECHNOLOGY
The Dräger X-zone 5000 can be charged in two ways: in the conventional wired manner or via a modern wireless induction charger. With the inductive charge cradle, the device is simply placed into the charger – alleviating the problems encountered with dirty charging contacts, etc. Additionally this non-contact charging possibility also allows maintenance and service to be carried out simultaneously.

CONFIGURABLE TO MEET INDIVIDUAL REQUIREMENTS
With the Dräger CC-Vision® PC software, the Dräger X-zone 5000 can be configured to meet individual needs and requirements. Alarm volume, visual cadences and frequency can all be adjusted. In addition, X-zones can be grouped to work as teams, so several groups of units can be set up to monitor different areas in close proximity without interfering with each other.



If you would like more information about the Dräger X-zone 5000 or other Dräger items please contact Forberg Scientific, Inc Process Sales Representative.

Installing the Wrong Pressure Transmitter Can be Dangerous

Author: Wika Application Notes

Whether it’s protecting human life, protection of expensive equipment, or meeting installation codes, safety is the number one concern when working in hazardous areas when there is a concentration of flammable gases, vapors or dust. Many pressure transmitter users in petrochemical, chemical, or refineries are unaware of the potential dangers of selecting the wrong pressure transmitter for their application. Using the correct pressure transmitter can mean the difference between causing and preventing a fire or explosion.

A non-rated pressure transmitter can create severe safety issues for both equipment and employees. Improper installation or use may damage the pressure transmitter making it a possible ignition source.

To help alleviate this concern, hazardous area pressure transmitters minimize these potential safety hazards. They are available in a variety of designs and approval ratings including explosion proof, non-incendive and intrinsically safe.

Hazardous Area Pressure Transmitters
Explosion-Proof pressure transmitters are based on the theory of containment and are designed for applications requiring Class 1, Division I approvals. These pressure transmitters are designed to contain, control, cool and vent any possible ignition, without igniting the surrounding flammable gases or vapors. They require installation with conduit and seal offs to maintain the explosion proof rating.

Non-Incendive explosion-proof pressure transmitters are preferred when potential hazards are only occasionally present. They are designed to work in Class 1, Division II hazardous areas and require less stringent installation procedures than explosion-proof pressure transmitters.

Intrinsically Safe explosion-proof pressure transmitters are designed to limit the thermal and electrical energy to a point where ignition is not possible. Intrinsically safe pressure transmitters require the use of an intrinsically safe barrier installed in the safe area. They do not require the use of conduit and conduit seals or need a “hot permit” if servicing of the instrument loop is required. This technology is standard in Europe and is becoming increasingly more popular in the United States.

Why Wika
Over the last six decades, WIKA Instrument Corporation has become a symbol for sophisticated solutions in the field of pressure and temperature measurement.
