![]() ![]() The natural frequency of tuning fork increases with increase in the length of tines. Margin decreases with increase in sensitivity. In vibrating fork for solids, changing the sensitivity may affect the hysteresis for the sensor. Changes to this frequency are continuously monitored. A piezo-electric crystal is used to oscillate the forks at their natural frequency. This prevents frequent toggling around the The Rosemount 2120 is a liquid point level switch designed using the principle of a tuning fork. This can cause fluctuations in both the amplitude and frequency of operation for the tuning fork.įor reliable level sensing a switching hysteresis is maintained around the swiching point. Vibrating fork switches are reliable and perfect for overfill prevention, high and low level alarm and pump protection even in the most challenging of. Turbulence can be caused by flow of material or due to an agitator or stirrer inside the silos. Switching Point Hysteresis for Point Level Switching Quality Vibration Type sensor vibrating level switch liquid sensor Explosion-proof stainless steel body tuning fork Level Switches with free worldwide. Vibrating Fork Level Sensor: Factory Calibration 11,200 5A Vibrating Fork Level Switch Sai Control System. The threshold frequency is set to match the natural frequency of tuning fork type level switch under Vibration Fork Level Switch Level & Flow Industrial Automation. The natural frequency of oscillation for the tuning fork level switch decreases as it covered
