Nowadays, more and more working conditions need to choose a pressure transmitter with explosion-proof function, and today’s article will introduce to you the difference between intrinsically safe explosion-proof and isolated explosion-proof pressure transmitter and how to choose. The intrinsically safe explosion-proof pressure transmitter is an electrical spark and thermal effect generated by the internal circuit of the equipment under specified conditions, normal operation or fault conditions, and the explosive mixture cannot be ignited. The intrinsically safe pressure transmitter fundamentally eliminates the generation of electric sparks or reduces the ignition point of electric sparks, so as to achieve explosion-proof functions. Intrinsically safe explosion-proof technology is generally used in complete sets, and safety barriers should be set up in the safety area, and the loops behind the safety barriers are intrinsically safe equipment. To put it simply, the circuit is explosion-proof and will not cause sparks. The isolated explosion-proof pressure transmitter is placed in an isolated explosion-proof enclosure for the parts that can generate spark arcing during the normal operation of the equipment. The isolated explosion-proof pressure transmitter housing can withstand the internal explosion pressure without damage, and can ensure that the internal flame gas is transmitted through the gap to reduce the energy, not enough to ignite the gas outside the shell. Isolated explosion-proof pressure transmitters isolate the energy of the explosion inside the chamber (product housing) and therefore do not detonate explosive hazardous gases outside the chamber in the event of a failure of the isolated explosion-proof transmitter. To put it simply, it is the shell isolation, through which the internal electrical spark is isolated from the outside contact. Explosion-proof pressure transmitters are widely used in petrochemical, daily chemical production, heat exchange stations, high-temperature steam pipelines, automation equipment, water treatment and other industries. Customers can choose to use intrinsically safe explosion-proof transmitters or isolated explosion-proof transmitters according to the characteristics of their working conditions.
