Product details
A rotating paddle level switch is a type of level sensor used to detect the presence or absence of a material at a particular point in a container. It is commonly employed in industries such as manufacturing, food processing, pharmaceuticals, and more, where accurate level monitoring is crucial for operational efficiency and safety. Here's how a rotating paddle level switch generally works: Sensor Design: The device consists of a shaft with a rotating paddle attached to one end. The rotating paddle is positioned within the container or vessel at the desired level. Operation: When the material in the container is above the set level, the rotating paddle is free to rotate. As the material level decreases, the paddle may start to encounter less resistance or become completely exposed to the air. Rotation Detection: The switch has a mechanism to detect the rotation of the paddle. Typically, this mechanism is connected to an electrical switch that changes its state (from open to closed or vice versa) based on the paddle's movement. Electrical Output: The change in the switch's state triggers an electrical signal. This signal is then used to indicate the level status to a control system, which can be part of a larger process control system. Adjustability: Many rotating paddle level switches are adjustable to set the specific level at which the switch should trigger. Material Compatibility: These switches are designed to work with a variety of materials, including powders, granules, and bulk solids. Applications: Rotating paddle level switches are commonly used in silos, hoppers, bins, and other storage vessels to monitor and control the level of materials. Advantages: Simple design and easy to install. Suitable for a wide range of materials. Reliable and cost-effective. Considerations: While these switches are versatile, their application may be limited in situations where the material may adhere to or build up on the paddle.
