The electronics of the sensor detects this change in frequency, and gives an output for presence or absence of the material. Temperature Range: -40 to 80☌ (-40 to 176☏) The tuning fork level switch is widely used, mainly for powders and small particles with a wide density range, such as the detection of the dust inlet and. The monitoring process of given parameters depends upon type of application media. Switch Output: SPST Selectable NO or NC states The working principle of vibrating fork level sensor is based on vibrating a tuning fork sensor continuously at its natural frequency and detecting the change of frequency and amplitude in the presence of application media. Factory calibration ensures accuracy over a wide range of liquids, including lubricating oils and hydraulic fluids. The tuning fork sensor is often used in conditions where there may be frequent composition changes in the liquid. The Level Switch incorporates a piezoelectric crystal that vibrates the fork. The change is analyzed and translated into a switching signal. The oscillating frequency changes as the fork enters the medium. As the tuning fork is progressively covered by a liquid, a shift in frequency occurs which activates the relay output. The Tuning Fork Level Switch is an ideal choice for level control of powders. For point level detection in liquids a sensor in form of a tuning fork is excited at its resonant frequency. The position of the switching point can be determined through the length of the tube extension.The LTU-101A-R consists of a sensor with dual tuning forks which are vibrated at a high frequency. The tuning fork is ideal for use either in adhesive and abrasive products as well as in bulk solids with very low density. The level switch detects reliably and robust the min. The VEGAWAVE 63 is a level switch for universal use in powders and fine-grained bulk solids. The unique fork design and inherent vibration characteristics of the fork type level switch can guarantee the automatic removal function. Figure 1: Vital Product Image 2 Operating Principle A specially shaped tuning fork is kept vibrating using piezo-electric elements. It has no moving parts and can replace rotating paddle level switch in most applications. The Tuning Fork Sensors are based on the principle of dual tuning forks, which vibrate at low frequencies. where the process temperature ranges between 0 C to +150 C. The tuning fork design is very robust and unaffected by buildup. Our tuning fork type level switch is suitable for almost all liquids, including coating liquids, aerated liquids and slurry, as well as powders with good fluidity and no adhesion. able for level detection in silos, bins, hoppers, etc. These sensors can be used to detect the presence or absence of granular, solid, or powder materials with densities as low as 2 lbs./cu.ft. When the 2130 is used as a low alarm, the liquid in the vessel drains down past the fork causing a change of natural. Changes to this frequency are continuously monitored. A piezo-electric crystal oscillates the forks at their natural frequency. The position of the switching point can be up to 6 m away from the installation site. Tuning Fork Level Sensors The Pulse Point is a tuning fork point level sensor that may be used to detect high and low levels in bins, tanks, and silos. The Rosemount 2130 is a liquid point level switch designed using the principle of a tuning fork. The working principle of the switch is to cause its vibration through the resonance of the piezoelectric crystal. Side Mount Media Type: Dry Material Tuning Fork Level Switch. The tuning fork level gauge is a liquid point level switch tool designed by the tuning fork principle. Relay Or Pnp Vibrating Fork Level Switches, Pole And Throw.
