The DustSense 10’s alarm levels can be set as a factor or percentage of the background level of particulate. The user has the ability to set the alarms to instantaneous or average levels above the background or normal level of emissions to indicate early warning of filter failure or gross failure detection. Alarm delay and data averaging are user selectable. Commissioning is simple and requires no tools or specialised equipment. The DustSense 10 series complies with the U.K.’s EPA for filter failure detection for Part A and Part B processes and European regulations for filter failure monitoring. Two versions are available - an “a” version, which comprises a separate sensor and control unit connected by a cable, and a “c” version, which s a combined sensor and control unit that is mounted in the stack or duct. Two separate alarm relay outputs are available within each mode.
