Dustalert 50 Intelligent Filter Performance Monitor

Supplier: Phoenix Instrumentation playlist_addCompare

The Dustalert 50 intelligent filter performance monitor continuously monitors and displays the relative emissions from Baghouses and other arrestment plant.

Price Guide (Inc GST): POA

The Dustalert 50 has many features which enable it to be specifically tailored to each customer's arrestment plant, taking into account different filter cleaning mechanisms and different processes.

The microprocessor-based sensor and receiver respond to any small change in the arrestment plant and can follow trends in output, or potential filter failure prior to absolute failure, by giving both a scalable 4-20 mA output (optional) and adjustable alarm output.

The sensing probe is connected by a standard multi-core cable to the control unit where the user interface is by a clear and simple touch pad control. All instrument parameters can be viewed on a digital display and the relative dust level is continuously displayed by a scalable bargraph as well as the digital display.

The microprocessor technology within the Dustalert 50 ensures reliable and flexible operation with internal electronic fault conditions quickly brought to the attention of the user.

Mode of Operation

A reference emission level is set within the instrument over a representative time period (for example over a number of filter cleaning cycles) when the plant is known to be operating efficiently.

Emission values received from the intelligent probe are processed and compared with the stored reference figure to produce an emission factor. The instrument incorporates a variable time constant analysis filter for smoothing of instantaneous data to allow observation of trends in filter performance.

An alarm is initiated if the emission factor exceeds the selected alarm factor and an alarm delay period is chosen to prevent false alarms caused by filter cleaning cycles.

Features of Dustalert 50 Intelligent Filter Performance Monitor
