Features

  • Operating temp: -94 to 500°F (-70 to 260°C)
  • Electronic self-checking and condition monitoring
  • Increased safety and proven FMEDA
  • Adjustable switching delay
  • “Fast drip” fork design
  • Rapid wet-to-dry time
  • No moving parts or crevices
  • Requires minimum installation

The Rosemount 2130 Level Switch is designed using the principle of a tuning fork. A piezo-electric crystal oscillates the forks at their natural frequency. Changes to this frequency are continuously monitored. The frequency of the vibrating fork sensor changes depending on the medium in which it is immersed. The denser the liquid, the lower the frequency.

When used as a low level alarm, the liquid in the tank or pipe drains down past the fork, causing a change of natural frequency that is detected by the electronics and switches the output state.

When the 2130 is used as a high level alarm, the liquid rises in the tank or pipe, making contact with the fork which then causes the output state to switch.

Additional features:

  • Virtually unaffected by turbulence, foam, vibration, solids content, coating products, and liquid properties
  • The mid-range temperature 2130 is designed for operation in process temperatures from –40 to 356 °F (–40 to 180 °C)
  • The extreme temperature 2130 is designed for operation in process temperatures from –94 to 500 °F (–70 to 260 °C). It has astainless steel thermal tube to move the electronics away fromthe process
  • Electronic self-checking and condition monitoring. The ‘heartbeat' LED gives status and health information on the 2130
  • 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

Applications include:

  • Overfill protection
  • High and low level alarms
  • Pump control or limit detection
  • Run dry or pump protection
  • Hygienic applications
  • High temperature applications
  • Wireless applications
