ข้อได้เปรียบทางเทคนิคหลัก
-
Mechanical Precision: The sensor features a knife-edged driver bearing and a plated brass ball bearing for the torque tube shaft. This design minimizes friction, allowing the controller to respond to minute changes in fluid specific gravity.
-
Application Versatility: Because it senses displacement (buoyancy) rather than just a simple float level, it is effective for monitoring the boundary between two immiscible liquids (interface) or detecting density changes in a single fluid.
-
Field Flexibility: The controller action is field-reversible from direct to reverse without needing additional parts. Sensors can be either right- or left-hand mounted to accommodate existing piping layouts.
-
Supply Pressure Conservation: To lower operational costs and reduce emissions, the relay exhaust opens only when the input signal changes, conserving supply air or gas during steady-state operation.
