Active Explosion Protection System Components
IEP Technologies – Dynamic Pressure “dp/dt” MEX Detector
Dynamic measuring cells in the detector sense changes in pressure. Once pre-programmed pressure values have been exceeded the detector reacts within microseconds to raise an alarm. The MEX Detector has up to two ceramic sensors within a single, solid housing. This is the only detector with algorithmic-based output and decision-making logic based on full-scale explosion tests, expert knowledge and application experience. The output and decision logic provides the highest detection security by evaluating the difference between an explosion pressure rise and process pressure variations. The ceramic cell sensors make the detector more resistant against mechanical damage and corrosive dusts, gases and liquids.

IEP Technologies – FAB Unit
By means of a field terminal box (“FAB”) the MEX Detector can be connected to various control units. Competitive advantages of the MEX Detector include:
- Dynamic pressure detection based on the characteristic temporal profile of pressure increase associated with confined explosion occurrences. This significantly increases false alarm immunity as well as detection security.
- Comprises two pressure-sensing cells to increase detection security and redundancy.
- Field-programmable unit to accommodate a wide range of hazard and process conditions. Also features a history buffer for programming set point during commissioning as well as diagnosis of incident after actuation.

IEP Technologies – Infrared and Ultraviolet Infrared Detectors
Optical detectors include infrared (“IR”) and ultraviolet infrared (“UV-IR”) detectors which are integrated in explosion prevention systems for specific applications. The IR detector is typically used in interconnected duct work for dust-handling systems. The UV-IR detector is used in combustible gas or vapor protection systems such as aerosol fill rooms and chemical storage rooms.

IEP Technologies – Static Explosion Pressure Detector
The IEP Technologies Static Explosion Pressure Detector is a low inertia detector incorporating a highly sensitive stainless steel diaphragm. The diaphragm is mounted onto a 6-inch diameter eight (8) hole nickel plated steel mounting flange. The flange is bolted to a cast aluminum housing protected by epoxy paint. The screw cover to the housing has an o-ring seal to protect the field adjustable switch assembly housed within. As standard, the pressure detector comes with a 24-inch long braided cable assembly. A standoff mounting kit is also available. The mounting kit consists of a stainless steel standoff pipe, a detector mounting bracket, a hose assembly, hose clamps, gaskets, and an adaptor plate.

IEP Technologies – Control Unit
A control unit is microprocessor-based and has both control and verification functions. It is comprised of control and battery charging circuits, a power supply and front panel which includes control and indication functions visible through a scratch-resistant window. A unit is packaged in an enclosure to provide superior dust contamination and weather resistance. Terminal access has been carefully designed for ease of installation.
Any signals emerging from the explosion pressure or flame sensors are recorded, tested and evaluated by the control unit. The monitoring and activation lines are continuously checked for wire breakage, earth fault and short circuit. Additionally, an automatic self-test system ensures that all important functions of the control unit are checked electronically. These control units provide both trouble relay contacts for process interlocking, and alarm relay contacts for notification should a system actuation occur.
