UDE-507 Series RF Admittance Level Switch Division in the technology based on existing product improvements, further enhanced the performance of products, and improve the exterior structure, to make products more reliable and attractive. It uses advanced RF Admittance technology to overcome Capacitance Level Switch can not eliminate the effects of conductive material defects linked. Reliable instrument, the technical instructions to meet or exceed the level of similar products, widely used in liquid, paste, powder, community-bit control. In addition, the product status indicators to increase the field work is a very high cost performance High Level Switch.
Structure principle
Level switch by the sensor unit and electronic unit. Sensor unit consists of three parts: the measurement probe, shielded pole and ground-side, the height of material reflected probe and container wall admittance changes, when the materials arrive at switch work, electronic unit to respond to the action-driven relay The output switch signals. Shielded pole to hang on to prevent the electrode material and produce error output signals, only when the material to really set point before the output relay on-off signals.
