Technical Characteristics and Safety Design
-
Directional Radiation Emission: The FQG60 features a specialized internal channel that allows the radiation beam to exit almost unattenuated in one specific direction. In all other directions, the heavy shielding attenuates the radiation to safe background levels.
-
High Source Classification: It is designed to hold sources with the highest safety classifications (e.g., DIN 25426/ISO 2919, typically C66646), ensuring that the radioactive material remains securely encapsulated even under mechanical or thermal stress.
-
Optimized Density Mounting: The container includes an integrated mounting device specifically for pipes. This makes it an excellent choice for density measurement of liquids, sludges, or slurries directly in the process line.
-
Manual Security Features: The ON/OFF switching mechanism is easy to operate manually and can be secured with a padlock or snap hook to prevent unauthorized tampering or accidental exposure. The switching status is clearly visible from the outside for instant safety verification.
-
Flexible Emission Angles: To adapt to different vessel diameters and pipe sizes, the FQG60 offers various angles of emission, allowing for an optimized radiation path tailored to the specific application geometry.

Primary Applications
-
Density Measurement in Pipes: Monitoring the concentration of acids, alkalis, or solids in suspensions within the process piping.
-
Point Level Detection: Serving as a high-reliability “limit switch” for high or low-level alarms in silos and tanks.
-
Small to Medium Vessels: Due to its compact and lightweight design, it is ideal for applications where space is limited or where larger containers would be too heavy for the support structure.
-
Abrasive and Corrosive Media: Because the measurement is non-contact (the FQG60 sits outside the vessel), it is the perfect solution for media that would destroy contact-based sensors.
-
Density Recalibration: When equipped with the optional calibration plate, the system allows for quick and easy density recalibration without needing to drain the pipe.
