Dust Alert 75

  • Designed to differentiate between gross failure and dust leakage from faulty/failing filter systems including bag filters
  • Automatic internal zero and reference self-checks for regulatory compliance
  • Selection of advanced features and options for improved performance
  • Increased quality assurance over previous models
Description

The DA75 is particularly suited for use on fabric filter type dust collectors (baghouses) and provides reliable and robust monitoring of particulate leaks from bags. With its compact cost effective transmitter design, pragmatic reliable monitoring can now be provided for all types of industrial bagfilters. The instrument benefits, first from PCME’s unique ElectroDynamicTM Probe Electrification technology, secondly advanced features enabling the DA75 to be configured for all types of bagfilters irrespective of cleaning sequence and finally an external display and self-check option which provides added quality control. The DA75 exceeds the requirements for a bag leak detector under EU regulatory compliance.

Features
Specifications

Bag leak monitoring performance

  •   High quality leak response with sufficient dynamic range and time response to track emissions from single and multi-compartment pulse cleaned bagfilters
  •  Instrument drift and minimum detection level below 0.1 mg/m3 with leak monitoring to 500mg/m3
  •  Fully configurable warning alarm and limit alarm levels with independent alarm delay
  •  Convenient bagleak output range in defined units (user selectable)

Automatic insulator contamination detection – option

Electrodynamic sensors are tolerant to dust contamination of the sensor rod (unlike Triboelectric systems) due to the non-contact measurement principle, however, build-up of conductive material across the insulator at the base of the rod can lead to error (as with all charge electrification systems). For standard dry dust collector applications, contamination is unlikely, but a possibility. The detection option provides a reliable method for detecting insulator contamination and hence improved Quality Assurance (for applications where water condensation is likely, PCME’s patented insulated sensor is a preferred option).

Electronics zero and reference drift detection – included as standard feature

Simulated dust signals are injected into the front end of the sensor electronics to ensure any electronic and signal measurement malfunction is automatically detected. This Quality Assurance Feature is required by European and ASTM (US) performance standards for Filter Leak monitors. This feature is controlled manually (standard) or automatically (optional).

User scaling of display – included as standard feature

The instrument can be specified with a choice of two forms of user scaling providing assistance to plant personnel wishing to manually scale the display to an approximate known dust level or those wishing to display emissions relative to a 100% full scale
