Versatile Gas Detectors Upgraded
May 03 2010
Honeywell (UK) have announced the release of Series 3000 MkII. Series 3000 MkII is a direct replacement for the company’s Series 3000 XPIS gas detector, offering a more robust Aluminium LM25 or 316 stainless steel enclosure. Additionally the enclosure now has two cable gland/conduit entries.
Series 3000 MkII is suited to a wide range of applications and can detect toxic gases or Oxygen in a 2-wire 4-20mA format. This wiring configuration makes the Series 3000 MkII ideal for retrofitting other 2wire devices including the Sieger Series 2000 range of 2-wire toxic gas detectors. A combination of hazardous area approvals ensures that Series 3000 MkII can be wired alongside other flameproof devices and still permit the ‘hot swap’ of a sensor, without the need to down-power the device or use a hot work permit. This type of certification approval also removes the need to segregate field wiring as required when IS (Intrinsic Safety) and Non IS field instruments are used in the same area, making the device both cost-effective and versatile. Series 3000 MkII also utilises a magnetically activated user interface, permitting configuration and calibration without opening the enclosure or having to obtain a hot work permit.
Series 3000 MkII offers excellent reliability and ease of use with smart gas sensors which configure automatically when plugged into the transmitter. Onboard diagnostics provide a wealth of useful information during operation and fault finding routines. In addition, the patented ‘Reflex’ sensors test algorithms to ensure sensing elements are fitted and operational at all times. For extra flexibility, the remote sensor can be mounted up to 15m (50 feet) away from the transmitter making the Series 3000 MkII the ideal choice for applications where the point of detection is located in a hard-to-reach area, e.g. in high or low level concealed areas or inside a room with the transmitter located outside.
The gas sensors available for the Series 3000 MkII include Oxygen, Carbon Monoxide, Hydrogen Sulphide, Chlorine, Sulphur Dioxide, Chlorine Dioxide, Nitrogen Monoxide, Nitrogen Dioxide, Hydrogen, Hydrogen Fluoride, Ammonia and Phosphine. Further releases will include Hydrogen Chloride, Hydrogen Cyanide and Ozone. Series 3000 MkII is ATEX, IECEx, UL and c-UL certified.
