![]() Electronic self-checking and condition monitoring.It has astainless steel thermal tube to move the electronics away fromthe process The extreme temperature 2130 is designed for operation in process temperatures from –94 to 500 ☏ (–70 to 260 ☌).The mid-range temperature 2130 is designed for operation in process temperatures from –40 to 356 ☏ (–40 to 180 ☌).Virtually unaffected by turbulence, foam, vibration, solids content, coating products, and liquid properties.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. 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. How It Works Video Case Studies Vibrating Fork Tools Featured Products Services Ensure safety and maximize efficiency with reliable and cost effective vibrating fork switches This low maintenance device, designed around the tuning fork principle, provides you with point level detection for alarm, monitoring, and control. The denser the liquid, the lower the frequency. The frequency of the vibrating fork sensor changes depending on the medium in which it is immersed. Changes to this frequency are continuously monitored. ![]() A piezo-electric crystal oscillates the forks at their natural frequency. The Rosemount 2130 Level Switch is designed using the principle of a tuning fork.
