Model
FS10000 Dry
Material Flow Switch |
|
The FS 10000 is designed to detect the flow of
dust through a filter in a dust collector or bag house. In some cases,
it can also be used as a flow / no-flow switch for powders or granulars
in chutes or pneumatic conveying lines.
When particles collide with the sensing probe, a small electrical
charge is transferred to the probe and sensed via the FS 10000's proprietary
circuitry. This charge transfer is called the triboelectric effect,
or "frictional electricity". The FS 10000 can detect dust
collector emissions before they are visible.
The FS 10000's output is via an on-board relay, that may be used to
sound an alarm or perform other control functions.
Features of the FS 10000 Include:
- Solid
state, no moving parts.
- Simple
installation and calibration.
- No
optics or lenses to clean or align.
- NEMA
4X enclosure for electronics.
- Optional
NEMA 7 or 9 enclosure.
- Explosion-proof
housing at probe.
- Field
adjustable time delay
|
Typical Applications
- Detect
torn filters in dust collectors.
- Pneumatic
conveying flow/no flow detection.
- Plugged
chute detection.

All necessary calibration indicators are on the
remote mounted electronics, so all you need to calibrate the FS 10000
is a small screwdriver. Calibration is performed under a no-flow condition.
Each unit has a field adjustable time delay that may be used to ignore
nuisance indications or intermittent gaps in product feed.
The FS 10000 comes complete with the electronic
circuit board mounted in a NEMA 4X enclosure, 15 feet of low noise
coaxial cable and connectors, and a 316 stainless steel probe mounted
in an explosion-proof enclosure.
An optional Shield Screen is available for the probe. The Shield Screen
is designed to shield the probe from unwanted electrical noise in
the duct that may be caused by nearby fans or motors. It can also
shield the probe from stray static electrical charges created in non-metallic
ducts. The Shield Screen bleeds the electrical noise to ground, before
it reaches the probe, while allowing the dust in the air stream to
collide with the sensing probe.
The FS 10000 is designed for applications
where the velocity is 1800 feet per minute or greater. To calculate
velocity when you know the CFM, use the formula: |
