Explosion Detection System – SUDetP

The SUDetP detector is an essential component in active explosion protection and isolation systems. It is compatible with suppression and chemical isolation systems, mechanical insulation with a knife gate valve or with a pneumatic valve.

The SUDetP detector is an essential component in active explosion protection and isolation systems. It is compatible with suppression and chemical isolation systems, mechanical insulation with a knife gate valve or with a pneumatic valve.

This sensor continuously monitors the process pressure and detects the overpressure characteristic of an incipient explosion in milliseconds. Its rapid response allows the immediate activation of the protection system, either to suppress the deflagration or to isolate it and prevent its spread to other areas of the installation.

Its robust design, certified for explosive atmospheres of gas and dust, makes it suitable for demanding industrial environments where reliability and speed of action are critical
