Wireless Gas Detection Sensors - Ideal for Mobile Applications
Detcon’s (USA) rugged new CXT- Series wireless gas detection sensors are designed for use in heavy industrial environments and especially suitable for mobile applications. These “environmentally bulletproof” field devices include fully encapsulated sensor electronics housed in a stainless steel enclosure, thereby eliminating potential damage that may be caused from water ingress. The CXT is equipped with one of two sensor technologies - electrochemical to monitor toxic gases, and infra-red for combustible hydrocarbons. Power is supplied by a rechargeable Smart Battery Pack or disposable battery options. When powered by the Smart Battery Pack, infra- red sensors can work continuously for more than six months, and indefinitely with accompanying solar panels.
While all CXT-Series gas detectors use an innovative “Self-Healing Mesh Network” topology, the CXT-300 is equipped with the most advanced innovation in network safety. Designed with Detcon’s patent pending “Fault Tolerant Safety Network” technology, the CXT-300’s processing power is shared among all network devices, allowing any device in the network to take over as “master” should the designated master device fail. Consequently, the CXT-300 does not depend on a single controller to maintain network operation and ensure safety. Detcon’s patent pending “Fault Tolerant Safety Network” guarantees no single point of failure.

IT’S WHAT’S INSIDE THAT COUNTS
MSA’s ALTAIR 4X and ALTAIR 5X are equipped with XCell sensor technology to provide increased performance, fast response time & reduced cost of ownership.
PERFORMANCE BEYOND WHAT YOU SEE
MSA XCell Sensors have a typical life of more than double the industry average, and are engineered using MSA’s pro prietary application- specific integrated circuit (ASIC) design.
By miniaturizing the sensors’ controlling electronics and placing them inside the sensor itself, MSA XCell Sensors offer superior stability under extreme environmental conditions, accuracy and repeatability.
In addition to MSA XCell Sensors, the ALTAIR 5X Multigas Detector can also be equipped with our wide variety of IR sensors covering many gases and ranges including CO2.

Toxic Gas Detector Offers Highly Accurate Ammonia Detection
The TS4000H Intelligent Toxic Gas Detector from General Monitors (USA) delivers accurate ammonia detection and protection, offering reliable monitoring for a variety of applications.
Because of its many uses, ammonia (NH3) is one of the most highly produced inorganic chemicals worldwide. It is used in the petroleum industry to neutralise the acids in crude oil to protect equipment from corrosion and by natural gas plants
as a method of NOx control. Ammonia is also used as a refrigerant in industrial refrigeration systems found in food and
beverage facilities and by the fertiliser industry to produce ammonium and nitrate salts. Despite its wide application, NH3 is caustic and hazardous, with exposure to high concentrations leading to lung damage and death. Exposure to gaseous ammonia is limited by the American Conference of Governmental Industrial Hygienists (ACGIH) to 15 minutes at 35 ppm and 8 hours at 25 ppm.
The TS4000H Toxic Gas Detector monitors ammonia in the 0-50 or 0-100 ppm ranges. Its precision electrochemical sensor has little to zero drift across its operational environmental conditions and one of the fastest responses in the market, with a T50 response of less than 15 seconds and a T90 response of less than one minute. The TS4000H measures NH3 to ±5 ppm or ±10% of reading, whichever is greater.
The TS4000H features advanced functions like HART, event logging, and support of asset management software. The system also displays fault codes for troubleshooting and provides complete status to the control room. All of its electronics are contained within an explosion-proof housing so that gas sensor information can be processed at the sensor site. The gas sensor may be remote mounted up to 2,000 feet (610 meters) away from the transmitter.
The TS4000H detector is easy to install and calibrates simply by activating a magnetic switch and applying gas. The interface module’s intrinsically-safe design also supports sensor field replacement without special tools or hot work permits.
The TS4000H ammonia sensor helps to protect people, equipment, and the environment in a broad range of industries where ammonia leaks are a hazard. For worldwide application, the detector complies with ATEX, CSA, CE, GOST, and is certified for use in SIL 2 environments.
In addition to ammonia monitoring the TS4000H can be configured to detect carbon monoxide, chlorine, chlorine dioxide, hydrogen, hydrogen chloride, hydrogen sulphide, nitric oxide, nitrogen dioxide, oxygen, ozone and sulphur dioxide.

Gas Detector Ensures Dependable Operation in Harsh Offshore Environments
Detector Electronics Corporation (USA), worldwide specialists in industrial fire detection, gas
detection and hazard mitigation systems, introduces the PointWatch Eclipse CO2 detector. An infrared fixed-point carbon dioxide (CO2) gas detector that provides non-intrusive calibration, and multiple communications options via 4-20mA, Modbus, relays and HART. Det-Tronics (USA) is part of UTC Climate, Controls & Security, a unit of United Technologies Corp.
The PointWatch Eclipse CO2 gas detector’s non-intrusive calibration allows a single person to calibrate the detector without declassifying the hazardous area, helping to reduce maintenance costs and improving uptime.
The PointWatch Eclipse CO2 gas detector continues the tradition of dependability proven by the model PIRECL combustible gas detector. Its heated optics feature allows constant operation even in extreme environments, making it suitable for petrochemical oil and gas applications.
“The reliable gas detection provided by the PointWatch Eclipse CO2 is ideal for monitoring CO2 to detect a loss of containment,” said Bryon Gordon, product manager, Det-Tronics. “This detector is designed to operate effectively under rapidly changing temperature and pressure conditions that occur
during a CO2 release.” In addition, the PointWatch Eclipse CO2 gas detector has been tested and certified to meet CSA, ATEX, INMETRO and IECEx requirements.
