The ALYK-200 tuning fork level switch is a new type of level switch. The fork body generates vibration by crystal excitation. The vibration frequency changes when the end of the fork body is immersed in liquid. The change is detected by an electronic circuit, and a digital value is output to realize the upper/lower level limit alarm and control. The tuning fork level switch is called "electrical float". It is used in scenarios where a float level switch is used or cannot be used due to scaling, turbulence, agitation, bubbles or other reasons. This switch is upgraded based on the float level switch, and eliminates the need of maintenance or adjustment as it has no moveable parts. This series of products is available in ordinary, intrinsically safe and explosionproof types, suitable for different scenarios.
Features
· Strong adaptability: "ELL signal analysis technology" can reduce the impact of various false echoes to ensure high reliability of products
· Maintenance-free: It is designed and produced based on IEC61508 standard to ensure high safety of products
· Calibration-free: It fully realizes the isolation of circuit cavity to ensure the safety of using electricity on-site
