Rosemount 2130 Series Fork Level Switch Vibrating Level Switch, Direct Load Output, Side or Top Mount, Aluminium Body / 8929356

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 °C Adjustable switching delay prevents false switching in turbulent or splashing applications ‘Fast Drip ‘ fork design gives quicker response time when mounted horizontally, especially with viscous liquids Rapid wet-to-dry time for highly responsive switching Fork shape is optimized for hand polishing to meet hygienic requirements No moving parts or crevices for virtually no maintenance Built-in diagnostics continuously check electronic and mechanical health Fork conditions detected including internal and external damage, coated or blocked, and extreme corrosion Ideal for critical alarm duties. Applications. Overfill protection High and low level alarms Pump control or limit detection Run dry or pump protection Hygienic applications High temperature applications
