An “intrinsically safe” classification and design means that an electronic circuit and it’s wiring will not cause any sparking or arcing and cannot store sufficient energy to ignite a flammable gas or vapor, and cannot produce a surface temperature high enough to cause ignition. Such a design is not explosion proof, nor does it need to be. High-power circuits such as for electric motors cannot use intrinsic safety methods for protection. When our instruments are installed in the same location as motor controls, “intrinsically safe” is not required. If our instruments is located in a hazardous area having explosive gas or vapor, most of the time, a cellular modem or external battery will be part of the installation and those are not “intrinsically safe”. The sensors supplied with the instruments are sealed, therefore no gas or vapor could get to any area of the sensor that could generate ignition conditions.
