Acoustic flow switch PulsarGuard 201 series

for solidshigh-temperatureclamp-on

The PulsarGuard acoustic sensor offers reliable solids flow detection, it detects structure-borne acoustic signals caused by the movement of material. This movement then causes impacts and frictional contact within a containment (e.g. the inside of a pipe). The sensor detects and reacts instantly to changes in solids flow and warns of blockages and foreign object detection, high flow, low flow, or no-flow conditions. Maintenance Free Measurement PulsarGuard series are non-contacting and maintenance-free. They are fastened to the outside of the structure, meaning minimal installation costs and zero shut downtime for your process. The compact design of the sensor means that it can be installed in the tightest of positions or environments. The high-frequency detection of the PulsarGuard picks up signals that are often undetectable to the human ear. They are not affected by outside noise which allows the sensor to be used in environments where there is a high degree of machinery or process noise without interference.
