FlowSwitch FS 780

Product catalog summary
Overview
The FlowSwitch FS 780 is a versatile dust monitoring and filter break detection device suitable for various industries such as aluminum, bakeries, cement, chemicals, and more. It is designed to monitor dust concentration behind filters, ensuring timely replacement of damaged filters to prevent production loss and environmental pollution.

Applications
The FS 780 is installed on the clean air side of filters to detect damage like cracks or assembly errors. It is crucial in environments with heavily contaminated air, strict emission limits, or where dust is reused. The device is adaptable for continuous or non-continuous operations and is available in high-temperature and food-grade versions.

Main Benefits
  • Prevents uncontrolled dust emissions and unnecessary cleaning.
  • Ensures clean recirculated air and compliance with emission limits.
  • Eliminates the need for additional emergency filters.
  • Fast detection of filter damage and unaffected by dust buildup.
  • Maintenance-free and easy to install.
  • Adjustable sensitivity and damping for flexibility across applications.

Functionality
The FS 780 operates on the triboelectric effect, detecting electrically charged particles near the sensor rod. It offers relay or analog output options and can be customized for various rod lengths and temperature ranges. Installation involves welding a threaded socket onto the pipe and drilling a hole for the sensor rod.

FlowSwitch FS 780-1

J Your safe choice Aluminum Bakeries Building materials Cement industry Chemical industry Fertilizer industry Food industry Glass production Mills Pharmaceuticals Power plants Pulp and Paper Steel industry Surface cleaning Wood industry etc. The FlowSwitch FS 780 monitors the dust concentration behind a bag or cartridge filter. It is installed on the clean air side of the filter. It identifies if a filter is damaged, e.g. by cracks, fractures or assembly errors. This allows to replace a damaged or broken filter in time, without losing production time and without polluting the shopfloor or environment. Dust monitors are especially important in case of heavily contaminated air, recirculation into the factory, strict external emission limits or dust reusage. The FS 780 is the most flexible device of its class and can be adjusted perfectly to your process. It is available with a relay or analog output, in high temperature versions, as food version and can be adapted for continuous or non-continuous operation.
