FlowSwitch FS 710
The FlowSwitch 710E is used for dust monitoring and for detecting filter malfunctions, such as those caused by cracks or assembly errors.
Its triboelectric measuring principle allows for reliable detection of dust penetration.

Key Features & Benefits
- Prevents uncontrolled dust emissions and unnecessary cleaning due to damaged dust filters
- Ensures recircled air is always clean
- Ensures that strict emission limits are fulfilled
- Saves the company from investing into additional police/ emergency filters
- Very reactive and fast detection of filter damage
- Is not affected by dust buildup on the rod- Robust design, well protected for several years of operation in a harsh environment
- Wear- and maintenance free
- Simple automatic calibration
- Easy to install into existing air ducts
Typical Applications
- FlowSwitch FS 710 monitors dust concentration behind bag or cartridge filters
- Installed on the clean air side of the filter
- Detects filter damage such as cracks, fractures, or assembly errors
- Enables early filter replacement before failure occurs
- Prevents production downtime
- Avoids pollution of the shopfloor and environment
Function
The measurement of the FS 710 is based on the tribo- electric effect. Particles collide permanently with each other and are charged in a natural way. If these electrically charged particles are flying next to the sensor rod of the FS710 or touch it, the particles are detected via a charge transfer. Resting particles, such as deposits etc., do not affect the measurement. An installation into an existing exhaust duct is possible without any problems. The sensor is capable of triggering a pre-alarm when a dust filter is showing first signs of wear, and a main alarm when a filter is broken.
More info
Two relays are used to make these signals available. This allows the operator to react in time and prevent an increase in dust emissions and reduce cleaning efforts. The design of the sensor is optimized for a long lifetime, and the unit is completely free of maintenance. A dedicated ATEX version is available and can be used up to zone 20/21.
To install a FS 710 a threaded socket is welded onto the pipe and a small hole for the sensor rod drilled. The sensor is fixed on the socket. The rod length should be at least 1/3 of the pipe diameter and the rod must not touch the opposite side. Calibration is done in clean air over a measurement period of 10 min. Sensitivity can be adjusted manually. Retrofits into existing ducts are easy and can be done within minutes
