Explosion Pressure Sensor / Transducer

Application Examples

Dust collectors
Spray dryers
Ductwork/Pipework
Fluidbed
Milling systems
Elevators

Available Options

One, two (confirm) or three (vote) pressure sensor logic configurations.

The PXD pressure transducer from Atex provides continuous monitoring of the Pressure rate-of-rise change in the protected process and signals or fires an explosion protection device when a predetermined explosion pressure rate of rise is detected.

Features

Continuous monitoring.
Records the pressure data after a triggered event for later analysis.
Data can be downloaded in Windows-compatible format.
Aseptic stainless-steel assembly.
Programmable rate-of-rise feature reduces probability of static triggering.
Configurable for different safety integrity levels (redundancy).
Due to solid stainless steel construction and ceramic membrane, can be installed in aggressive environments.

Concept and Operation

The sensor continuously monitors the pressure and/or rate-of-rise in a protected vessel or connecting ductwork. It analyses the signal, determines if it fits the parameters associated with an explosion and sends a signal to a system controller. Each Sensor unit is fully programmable for its location, hazard and protected volume. The connected Logic Box is also programmable to meet the configuration needs. On receiving a discharge signal the controller can activate the Dry Chemical Suppression system (sodium Bicarbonate) or Hot Water Suppression system, integrate process control, and notify operations personnel of the event.
