Dust monitors

Sigrist dust monitors have been applied for over 30 years for measuring dust concentration in production processes or in the ambient air to ensure good working conditions and minimize air pollution.
1. StackGuard 2 System NEW PRODUCT!
Dust Emission Measuring System.

The StackGuard continuously monitors the scatted light intensity of an extracted, withdrawn sample of gas. The laser light source minimized stray light and improves sensitivity to the g/m level, the filtered purge air prevents from window soiling. A calibration check is performed by means of a checking rod. The sample air is led out of the stack, heated up above the dew point and then fed through the measuring cell.

2. FireGuard 2
Smoke Detector.

The FireGuard detects emerging fires already at their early stages (cold smoke). The sensor uses the available natural air stream in the tunnel. Any influence caused by fog will be eliminated by optional heating elements. The sensor is very compact and has neither movable parts nor wear parts nor does it need consumables.

3. StackGuard
Dust Concentration Monitor for Hot Gasses.

The StackGuard continuously monitors the scatted light intensity of an extracted, withdrawn sample of gas. The laser light source minimized stray light and improves sensitivity to the g/m level, the filtered purge air prevents from window soiling. A calibration check is performed by means of a checking rod.

4. VisGuard 2 Extractive
Visibility Monitor.

The VisGuard measures the scattered light intensity of a sample drawn into the instrument. Filtered purge air is fed through the flow cell, thus enveloping the sample in a protective shroud of clean air. This effectively keeps the optics clean. Installations are either in the tunnel cavity/niches (in-situ) respectively using extractive sampling away from the cavity. An optional sample heater eliminates the influence of any mist effects.

5. VisGuard 2 In-Situ
Visibility Monitor.

The VisGuard measures the scattered light intensity of a sample drawn into the instrument. Filtered purge air is fed through the flow cell, thus enveloping the sample in a protective shroud of clean air. This effectively keeps the optics clean. Installations are either in the tunnel cavity/niches (in-situ) respectively using extractive sampling away from the cavity. An optional sample heater eliminates the influence of any mist effects.

6. VisGuard OMD
Oil Mist Detector.

The VisGuard measures the scattered light intensity of a sample drawn into the instrument. Filtered purge air is fed through the flow cell, thus enveloping the sample in a protective shroud of clean air. This effectively keeps the optics clean. Oil dust in the sample can be detected early to help preventing from further incidents.
