Nowadays, more and more working conditions need to choose a pressure transmitter with explosion-proof function, today this article will introduce you to the difference between intrinsically safe explosion-proof and isolated explosion-proof pressure transmitter and how to choose.
Intrinsically safe explosion-proof pressure transmitter is a circuit inside the equipment under specified conditions, under the specified conditions, the electric spark and thermal effect generated under normal operation or fault conditions can not ignite the explosive mixture. Intrinsically safe pressure transmitters fundamentally eliminate the generation of electric sparks or reduce the ignition point of electric sparks, so as to achieve explosion-proof function.
Intrinsically safe explosion-proof technology is generally used in a complete set, to set up a safety barrier in the safety area, the circuit behind the safety barrier are intrinsically safe equipment. Simply put, the circuit is explosion-proof and will not cause sparks.
The isolated explosion-proof pressure transmitter is a component that can generate spark arcing during normal operation of the equipment and placed in an isolated explosion-proof housing. The isolated explosion-proof pressure transmitter housing can withstand the internal explosion pressure without damage, and can ensure that the internal flame gas propagates through the gap to reduce the energy, which is not enough to ignite the gas outside the shell.
The isolated explosion-proof pressure transmitter isolates the energy of the explosion inside the cavity (product housing), so that the explosion-proof transmitter will not detonate the explosion hazardous gas outside the cavity after the failure of the explosion-proof transmitter. Simply put, the shell isolation is isolated through the shell to isolate the internal electric spark from the outside world.
Explosion-proof pressure transmitters have a wide range of applications 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 own working conditions.
