![]() ![]() They are also suitable for mining, chemical processing, and food and beverage applications. The models are easy to use and are ideal for controlling powders and fine-grained vibrating fork for solids. What is the use of tuning fork level switch?Ī tuning vibrating fork level switch for solids is a sensor that generates an electrical contact at a certain level. The threshold frequency is set to match the natural frequency of tuning fork type level switches under water. When the amplitude drops below a set threshold, the onboard electronics changes the outputs (relays).Īs the tuning fork type level switch is covered with liquid application media, its natural frequency decreases. It is important to consider the type of application media when monitoring given parameters.ġ.Amplitude of vibration: Vibrating Level Switch for SolidsĪs the material level increases and comes into contact with the Vibrating Fork tines, the amplitude of oscillation of tuning fork level switches dampens. Vibrating fork level sensors operate by vibrating tuning fork level sensor continuously at their natural frequency and detecting the change in frequency and amplitude when application media is present. It may sometimes have a voltage-free contact, or sometimes it may have a fixed voltage of 0-12. A level switch's output can be voltage dependent or not, depending on the device. In the event of a variation in the level, the device raises an alarm or produces a sound. It works like any alarm switch that turns on/off when the level of fluid goes above or below a predetermined level. Vibrating fork level switch working principle: This prompts it to actuate an alarm, pump or valve. When the forks are exposed to liquid, the frequency drops and this is detected by the switch electronics. These models also feature two forks that vibrate at their mechanical resonance frequency, allowing them to self-clean when they come into contact with air. As it contacts the material in a tank, its oscillation stops, prompting the switch to output a detection signal. Vibration type level switches are composed of a vibrating rod made from stainless steel. It is the most widely used product in the material (liquid) level switch instrument. The product can adapt to the harsh working conditions and work reliably. When the vibrating fork for pharmaceuticals is subjected to medium damping, the vibrating fork for solids stops vibrating, and the control circuit drives the relay to send out a switch signal. The sensing part for detecting the material (liquid) level is composed of the vibrating fork for liquids, which has a fixed vibration frequency and amplitude vibration. No need for adjustment - since the detection of tuning fork limit switch is not affected by the electrical parameters and density of the measured medium, no matter what liquid is measured, it does not need to be adjusted on site.The vibrating fork level switch for solids is designed using the principle of the damping effect of the medium on the v ibrating fork vibration and the piezoelectric effect. Maintenance free - since the detection process of tuning fork limit switch is completed by electronic circuit and there are no moving parts, maintenance is not required once it is installed and put into operation.ģ. Harsh conditions such as scaling, agitation, turbulence, bubbles, vibration, medium viscosity, high temperature and high pressure also have no impact on the detection.Ģ. Strong adaptability - different electrical parameters and densities of the tested materials have no impact on the measurement. For all kinds of liquids, such as slurry, sticky, easy to foam, corrosive and other media limit detection.ġ. It is mainly aimed at the powder and small particle materials with a wide range of density, such as the detection of inlet and outlet pipe blockage of the dust collector, the material level measurement of the ash hopper of the dust collector, and the limit measurement of plastics, rubber powder, flour, various grain crops, food, chemical products and so on. ![]() Tuning fork switches are usually used with level meters to control and measure materials. G1 ", G3/4" thread or Flange (Customize) It may indicate that under customary adjustment Tuning fork and output were working condition, all with LED indication It is practical and simple, reliable, and applicability These changes will be detected by the internal electronic circuits, and then after treatment, converted into a switching signal. Drastically reduced the amplitude and the frequency and phase of significant change. Tuning fork vibrating level switches, by resonant piezoelectric crystal to cause their vibration,When subjected to material damping. ![]()
