Rosemount 2130 Vibrating Level Switch Rosemount’s 2130 vibrating level sensors work on the principle of a tuning fork to deliver accurate and reliable level measurement unaffected by turbulence, foam, vibration, solids content, coating products, and liquid properties. The switches forks are oscillated at their natural frequency using a piezo- electric crystal. When forks come into contact with a fluid the oscillating frequency change that occurs is detected by the 2130 level switch and causes a change in output state.The 2130 vibrating level sensor is simple to install and requires no calibration or maintenance. Internal diagnostics and LCD lights give a visual indication of the unit’s operational status and health and a magnetic test point allow for easy functionality checking. Features & Benefits Designed for operation in process temperatures from –40 to 180 °CAdjustable switching delay prevents false switching in turbulent or splashing applications’Fast Drip’ fork design gives quicker response time when mounted horizontally, especially with viscous liquidsRapid wet-to-dry time for highly responsive switchingFork shape is optimized for hand polishing to meet hygienic requirementsNo moving parts or crevices for virtually no maintenanceBuilt-in diagnostics continuously check electronic and mechanical healthFork conditions detected including internal and external damage, coated or blocked, and extreme corrosionIdeal for critical alarm duties Applications Overfill protectionHigh and low level alarmsPump control or limit detectionRun dry or pump protectionHygienic applicationsHigh temperature applications 振动液位开关
