Detection Devices
SmartDS Dynamic Dectection System
Dynamic measuring cells in the detector sense changes in pressure. Once pre-programmed pressure values are 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 to mechanical damage and corrosive dusts, gases and liquids. By means of a field terminal box (“FAB”) the MEX Detector can be connected to various control units.
Advantages of MEX Detectors
- 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.
- Utilizes 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.

Static Pressure Detector
Static pressure detectors are used in stable processes that only have one threshold (at which point the detector is activated). The detector is field-adjustable as well as FM approved. These detectors are typically mounted in pairs with vibration isolation standoffs to minimize the risk of false alarms due to operator errors. Static pressure detectors are dependable, reliable and have a proven track record.

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.
