Adaptability Analysis of the Applications of Fork Level Switch and Vibrating Rod Level Switch - 1

Adaptability Analysis of the Applications of Fork Level Switch and Vibrating Rod Level Switch Fork Level Switch and the Vibrating Rod Level Switch are point level switches, which are commonly used for high and low level alarms in solid level measurement to prevent overflow and dry operation. Fork Level Switch and Vibrating Rod Level Switch are both based on the vibration principle of the cantilever beam. The probe (fork tines or rod tube) is driven by a piezo-crystal assembly to oscillate at a natural frequency. When in air, the probe vibrates at its natural frequency; when solids cover the probe, the frequency of oscillation drops and is detected by the integrated circuit, which in turn changes the output state.

Adaptability Analysis of the Applications of Fork Level Switch and Vibrating Rod Level Switch - 2

The probe of Fork Level Switch is composed of two enlarged fork tines. By reasonably widening the fork bodies and precisely tuning, the measurement sensitivity is significantly improved. With a minimum measurable density of 0.008g/cm ³, Fork Level Switch is ideal for the level measurement of fine sand, flour, foam particles and powders. However, there are some limitations in some of the applications. Due to the large amplitude of the forks, when measuring the fine powder, the forks might be in a hollow state, resulting in delay or false alarm. In addition, for materials with large diameter...
