Gas Detectors Receive CSA Approval
Tyco Gas & Flame Detection is pleased to announce that the BM 25A and BM 25AW (wireless) have been certified to Canadian Standards Association (CSA) and now carry the CSA mark of approval for use in hazardous areas.
Both the BM 25A and BM 25AW meet CSA Standards as intrinsically safe for use in Class I, Division 1 hazardous locations in Canada and certified for use in Class I, Division 2 hazardous locations in the United States.
The BM 25 is a versatile multi-gas monitoring system that offers exceptional flexibility for a wide range of applications. The system detects up to 5 gases simultaneously and can include up to 30 devices in a mesh network. By using up to 16 BM 25AW (wireless) units in combination with an X40 wireless controller, information can now be centralized at one location, displaying up to 32 measurements in real time.
Using the Sitewatch option, the MX 40 can be accessed remotely via Ethernet or GSM. A web page displays measurements and channel statuses in real time, and is accessible from any computer or wireless phone connected to the internet. This option also allows information to be delivered by SMS or email.

Senscient ELDS™ fully available by MSA - Laser-based Open Path Gas Detection
The Senscient ELDS laser-based open path gas detector by MSA is capable of detecting a wide range of flammable (methane, ethylene, sour gas) or toxic gases (ammonia, carbon dioxide, hydrogen chloride, hydrogen fluoride, hydrogen sulfide) for a broad range of industrial, oil and gas production and petrochemical processing applications. Its patented technology eliminates false alarms and enables faster, more reliable detection of hazardous gases, thereby improving worksite safety while reducing operational costs.
The Senscient ELDS gas detector uses a tuneable laser to produce a unique Harmonic Fingerprint™ specific to the target gas, making it immune to cross-interferent gases that cause false alarms. Senscient ELDS devices are gas-specific and operate at a wavelength less prone to water vapour interference, giving greater reliability and performance in challenging environments, such as fog, rain and snow. SimuGas™ automated integrity checks eliminates the need for gas checks. The system does not require consumable sensing elements or calibrations, significantly reducing operation costs for time and materials spent on maintenance.
Open path gas detectors are used to monitor for fugitive emissions, protect personnel and warn of plant failures. These devices are typically located to provide a detection barrier around the perimeter of a plant, process or storage area; or positioned in close proximity to specific items of plant, that pose a real risk of gas escape: e.g. pump sets, pressure reducers, valves and pipe flanges.
The Senscient ELDS gas detector has a T90 response time within three seconds. Depending on its configuration, it can detect gas over a path length of 60m, 120m or 200m. Its electronics are contained within an explosion-proof stainless steel housing. It has CSA, UL, ATEX, IECEx, EAC and Inmetro approvals, and is suitable for use in SIL 2 systems.
Senscient ELDS™ gives you the utmost confidence in gas detection. For further information please [click here](

For More Info, email: email:
The IR series of infrared gas detection sensors, from N.E.T. use the technique of NDIR (Non Dispersive Infrared) to monitor the presence of SF6 or refrigerants. This technique is based on the fact that the gas has a unique and well defined light absorption curve in the infrared spectrum that can be used to identify the specific gas. The gas concentration can be determined by using a suitable infrared source and by analysing the quantity of energy absorbed from the gas inside the optical path. The IREF-P sensor is equipped with electronics and firmware in order to provide an output that is linearised and temperature compensated. The output is analogue voltage type [0.4 V—2 V] dc (other voltages are available on request). IREF P is now SIL2 approved.
The main features are: analogue voltage standard output, incorporated signal, linearisation and temperature compensation suited for instrument manufacturers without any specialist knowledge in IR technology, standard sensor size 32 mm, fast response, solid, rugged construction, wide operating temperature and humidity range (-20°C +60°C) and new optics “Variable Geometry”.
NDIR Sensors are now available for the following detectable gases: SF6, R-1234yf, R-507, R-125, R-134a, R-404a, R-407a, R-410a and R-449 Other refrigerants are in development.

Stay Active in Gas Detection with the new IR DYNAMIC RANGE SENSOR from N.E.T The New Dynamic sensor
introduced by N.E.T. is designed to meet the necessity of costumers for a more accurate detection of Methane over 0-100%Vol range using
the technique of NDIR (Non Dispersive Infrared).
Integrated electronics and factory calibration, of DYNAMIC sensor provides an output linearised and temperature compensated to reach the highest sensing accuracy ever seen on an IR Methane sensor.
DYNAMIC sensor also provides an optional digital output linearised and temperature compensated to detect Propane over 0-2.1% Vol range, which is the best choice for detection of other hydrocarbons using a cross-reference factor.
Digital, analogue or both output can be used to monitor the functionality. By using digital communication, concentration and status of the sensor can be easily monitored for a fast check of the system, while analogue output offers the fastest and easiest way to check the gas concentration.
Rugged, fast, flexible and easy to use, DYNAMIC sensor is suited for instrument manufacturers who needs to detect Methane and Propane in compliance with Chinese Mine standard.
The main features are:
• High sensitivity for superior accuracy over 0-100% Vol range of Methane • Resolution of 0.01%Vol over 0-100% Vol range • Dual gas digital output (Methane + Propane) • Analogue (voltage or pellistor) standard output for Methane or Propane
• ATEX & IECEx certified NDIR sensor • Fast response
