Installation Guide for Hazardous Areas
From wilcoxon.com

The concept of intrinsic safety in wiring recognizes that ignitable, flammable or combustible materials will be present with air, or other oxidizer, in sufficient quantity and ratio so as to represent a fire or explosion hazard. These mixtures could easily be ignited by a match or other open flame, but just as easily could be ignited by a high energy spark. Consequently, the wiring used in areas where these mixtures are present can be implemented in a fashion to absolutely preclude any possibility of igniting these mixtures. That is the essence of intrinsic safety!

Intrinsically safe wiring will never have enough energy available within the hazardous defined area to ignite any explosive or combustible mixture. This concept is applied to mixtures of gasses, dusts, or metals.

 


Products & Services
Gas transmitters consist of an enclosure, sensor, and electronics that convert a signal from a gas sensor into an analog output signal (typically 4-20 mA).
Intrinsic safety (IS) barriers are devices that limit the current, voltage, and total energy delivered to a sensor in a hazardous area or flammable environment in order to prevent an explosion.
Gas sensors interact with a gas to initiate the measurement of its concentration. The sensor then provides output to an instrument to display the measurements.
Electronic and semiconductor gases are specialized for microelectronic manufacturing or semiconductor processing applications such as thin film deposition (CVD, PVD), etching, RTP, packaging or soldering.
Gas and air instruments detect, monitor or analyze gases present in an environment.
