Snifter A1+ Filter Leak Monitor

Snifter A1+ is a low-cost easy to use filter leak detector. This filter leak detector is a direct replacement for the Snifter A1 device. Snifter A1+ can be used for monitoring outlets in a baghouse enabling fast identification of leaking compartments. Commissioning of the device is easy with the convenient auto setup function which identifies normal dust concentration within ten minutes of installation.

The Snifter A1+ dust monitor has two pre-set alarm limits for alarm and alert signals to give plant operators information on leaks and deteriorated filtration performance.

EX models (IECEx and ATEX) are available on Snifter A2 model and upwards.

Description

Technical Description – Snifter A1+ 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 A1+

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.

The fast response time of the Snifter enables the earliest detection of broken filter systems and helps prevent loss of expensive product to the environment.

Equipped with two fixed alarm signals, Snifter A1+ provides the plant operator an alert for small increases in the dust concentration as well as a notification for bigger breakages. With Sintrol’s automatic setup function, the monitor can be functioning within 10 minutes of installation.
