Technical Characteristics and Enhanced Safety
-
Maximum Activity Capacity: The FQG62 is designed for heavy-duty penetration, supporting significantly higher source activities than the FQG60 or FQG61. This is essential when measuring through massive steel structures or dense catalysts.
-
Spherical Shielding Efficiency: Its geometry provides the most effective shielding-to-weight ratio, ensuring that radiation is strictly channeled through the emission window while being attenuated to safe levels in all other directions to protect personnel.
-
Remote Pneumatic Switching: To enhance plant safety, the FQG62 can be equipped with pneumatic actuators. This allows the radiation beam to be toggled ON or OFF from the control room, reducing the need for personnel to enter high-radiation or high-temperature zones during maintenance.
-
Triple Locking Security: The device offers flexible and robust security options, including a padlock, cylinder lock, or a heavy-duty locking bolt to fix the switching position, preventing unauthorized exposure.
-
Unrestricted Process Conditions: Because the FQG62 is mounted externally, the measurement is completely unaffected by internal tank pressure, vacuum, or extreme temperatures that would destroy internal sensors.

主な用途
-
Massive Chemical Reactors: Level and interface measurement in the largest industrial reactors where high-activity sources are mandatory for a reliable signal.
-
Coal Gasification and Smelters: Monitoring levels in extremely dense or heavy media where standard radiation levels would be absorbed before reaching the detector.
-
High-Pressure Autoclaves: Providing non-invasive measurement through thick, high-pressure steel walls where no process openings are permitted.
-
Safety Instrumented Systems (SIS): Integrating the pneumatic version into SIL-rated safety loops for automated overfill prevention in critical chemical processes.
-
Mining and Slurry Monitoring: Measuring the density of highly concentrated mineral slurries in large-diameter pipes or tanks.
