ATEX dust detector

for monitoring of damage to dust extraction units

The ATEX dust meter is designed for use in harsh industrial environments (including explosive atmospheres) to monitor dust levels in ducts and pipelines. It is most often installed on the clean side of the filters and is used to monitor the correct functioning of the dust extraction units. This allows damage to the filter bags to be detected immediately.

The probe is placed directly at the measuring point, and the automatic set-up of the dust meter takes a maximum of eight minutes, making the device virtually maintenance-free and low-cost to operate afterwards.

Parameters of the dust meter

The ATEX Snifter A2 dust meter has sufficient sensitivity to cope with the monitoring of low dust concentration levels resulting from the use of modern fabric filters in dust collectors. The stainless steel probe and cast aluminium housing mean that the monitor will operate continuously with minimum maintenance, withstanding vibration from the process and the deposition of dust on the probe.

The use of dust measurement and monitoring
in the filtration and dedusting process

Dust detector snifter

Dust sensors monitor the condition of the filters

You will immediately detect filter bag damage or leaks, and in the long term you will optimise the maintenance frequency.

With Ex-rated dust meters, you minimise the risk of explosion

You act preventively and prevent an explosive atmosphere from forming on the clean side of the filters.

Dust detector snifter

You monitor the quality of the air flowing into workplaces

You take care that dust extraction really does its job and provides employees with safe working conditions.

Reliable method for monitoring dust concentration: inductive electrification

The principle of dust measurement is extremely simple, which only enhances the sensitivity of the device providing high measurement accuracy. The most important part of the dust meter is the probe which is placed inside the duct, perpendicular to the air flow. When dust particles moving inside the channel pass or hit the sensor probe, a signal is induced. It is then transmitted to the monitoring system, for example to a computer with monitoring software. In addition to its high sensitivity, this technology also minimises the impact of sensor contamination, process temperature variations and flow velocity on measurement results. Inductive electrification technology enables a detection limit of just 0.01 mg/m3 to be reached.

8 minutes

that is all it takes to automatically set up the dust meter.

Instant, simple and user-friendly configuration is one of the meter’s many advantages. During the automatic configuration procedure under normal process conditions, the dust monitor automatically adapts to the process conditions and sets the measuring range and alarms accordingly. Under normal conditions, the unit will light up green and the mA output will be set to 5% of the range.

Dust detector snifter

The unit can be installed in the contaminated air ducting to the filter as well as in the ducts on the clean side of the dust extraction unit. In both cases, no manual range configuration is required.

The baseline thus determined is always stored in the device’s memory. Then, using a switch mounted in the unit, you can very quickly set one of the three sensor response modes. When the response mode is changed, the device applies the appropriate multipliers to the baseline and automatically adjusts the ALARM and ALERT threshold parameters. All device parameters can also be adjusted manually in the DustTool software.
