Technical Characteristics and Flexible Operation
-
Higher Activity Capacity: The FQG61 is built to handle high-activity sources, making it suitable for very large vessels, thick-walled reactors, or high-density media that require stronger radiation to penetrate successfully.
-
Optimized Spherical Shielding: The spherical shape provides a more efficient ratio of weight to shielding effectiveness. This allows for a relatively compact device that still meets the strictest international safety standards for radiation damping in non-measurement directions.
-
Manual or Pneumatic Switching: For enhanced safety and automation, the FQG61 can be equipped with pneumatic switching. This allows the radiation beam to be opened or closed remotely from the control room, which is ideal for high-risk areas or SIL-rated safety systems.
-
Secure Locking Mechanisms: To prevent unauthorized or accidental exposure, the device features multiple locking options, including a padlock, cylinder lock, or locking bolt. The “ON” or “OFF” status is clearly identifiable at a glance.
-
Diverse Isotope Compatibility: It is designed to safely house either Cesium-137 or Cobalt-60 , providing flexibility based on the penetration requirements of the specific process medium and vessel thickness.

主な用途
-
Thick-Walled Reactors: Level and density measurement in high-pressure chemical or petrochemical reactors where heavy steel walls require the high-activity sources the FQG61 can provide.
-
Large Storage Silos: Continuous level measurement in tall solids silos where the radiation must travel across a significant distance.
-
Automation and Safety Loops: Utilizing the pneumatic switching version for remote-controlled safety shutdowns or for use in SIL-certified safety instrumented systems.
-
High-Density Media: Measuring the density of heavy slurries or concentrated chemicals where standard low-activity sources would be completely attenuated.
-
Extreme Process Environments: Since the container is extraneous to the process, it remains unaffected by internal heat, pressure, or chemical aggression.
