Technical Description – Snifter A2 Filter Leak Monitor
Inductive Electrification
Sintrol dust monitors are based on a unique Inductive Electrification technology. The measurement is based on particles interacting with an isolated probe mounted into the duct or stack. When moving particles pass nearby or hit the probe a signal is induced. This signal is then processed through a series of Sintrol’s advanced algorithms to filter out the noise and provide the most accurate dust measurement output.
Classic triboelectric technology is based on the DC signal, which is caused by particles making contact with the sensor to transfer charges. Compared to DC based measurements, the Inductive Electrification technology is more sensitive and minimizes the influence of sensor contamination, temperature drift and velocity changes. By using the Inductive Electrification technology, it is possible to reach dust concentration measurement thresholds as low as 0.01 mg/m3.
A Closer Look
Snifter A2
Once installed, Snifter’s automatic setup function will adjust itself to the dust flow conditions of your application and use alarm signals to notify you of bag breakages. Snifter has the necessary sensitivity to meet low levels of dust concentrations in modern fabric filters. Additionally, the quality of the measuring principle and enclosure ensure that the monitor will run continuously with minimal maintenance while withstanding vibration from the process or dust build up on the probe.
Snifter A2 is an advanced filter leak detector. This dust monitor can be used to monitor the operation of a baghouse and alarm the operator when dust levels increase. Snifter A2 supports Sintrol Network connectivity over USB and RS485 interfaces by default. All parameters and settings are user selectable to best suit custom application needs. This device is fully compatible with Sintrol DustTool software.
Auto setup function makes commissioning easy and quick and two independent alarm signals enable easy connectivity.
EX models (IECEx and ATEX) available. Wireless RF communication available.
