Asosiy texnik afzalliklar
-
Dependable Control Logic: The two-stage proportional relay with integral action ensures that the controller responds predictably to level changes, providing stable operation even when process conditions fluctuate.
-
Pressure and Vibration Immunity: Unlike simpler float switches, the L2 design minimizes the impact of O-ring friction and process pressure sensitivity. This means its performance remains constant even as vessel pressure changes, and it stays functionally “silent” during high-vibration scenarios.
-
Extreme Pressure Rating: When equipped with a Polyvinylchloride (PVC) displacer, the sensor assembly is rated for ASME B16.34 CL1500 service. This makes it suitable for high-pressure separators and scrubbers.
-
Field Flexibility: The controller and displacer can both be reconfigured in the field for direct or reverse action and vertical or horizontal mounting—all without needing to order additional parts.
-
Environmental Compatibility: Because the exhaust can be piped away, these units are ideal for remote locations where sweet natural gas is used as the supply medium instead of compressed air.
