The TFLS2 incorporates a piezoelectric crystal that. Comes standard with a user friendly PNP/NPN configurable output.įinally, Lime, Styrofoam, tobacco, dry cereals, sugar, animal feed, milk powder, flour, insulation, cement, paper shavings, plastic granules, sawdust, carbon black, light fibers, detergent powders, dyes, chalk, silica, sand, wood chips, Chemical processing, Pulp and paper processing, Mining, Food and beverage. The Model TFLS2 Compact Tuning Fork Level Switch is an ideal choice for level control of powders. In addition, the Tuning Fork Level Switch is not affected by the dielectric constant of the sensed material, making it superior to a comparable capacitance level switch for applications where the dielectric constant is low, more than one material is being used in the single vessel, and when material moisture content can change.Īlso, The Level Switch is also great for applications when the bulk density is too low for a rotating paddle level switch, making it the ideal choice for low density bulk solids and liquids. The Level Switch is easy to use with no calibration required, and no mechanical moving parts mean no routine maintenance. The tuning fork type level switches working principle based upon detecting the change in harmonic vibration frequency of the sensing element as a result of the.

Applications in places a larger tuning fork level switch may not be suitable, providing great versatility.
TUNING FORK LEVEL SWITCH FREE
In addition, as the fork becomes free of material, the switch changes back to its normal state.Īlso, it’s compact size and DIN connection allow for application.
Extension Type Level sensor housing Built-in box, aluminum coating IP66/IP67 Power supply Probe construction Voltage endurance capability Overvoltage protection Storage temp. Also, when the fork comes in contact with a material, the vibration is dampened and the switch changes state. SC35 TUNING FORK LEVEL SWITCH SC351 High-temp. The Level Switch incorporates a piezoelectric crystal that vibrates the fork at its natural frequency. Time delay: 0.The Tuning Fork Level Switch is an ideal choice for level control of powders. The liquid level switch output can then be utilised by other instrumentation to open a valve. The tuning fork level switch can be widely applied. A specially shaped tuning fork is continuously. vibration frequency of the tuning fork and outputs a switch signal. Minimum material density sensed: Solid: >/= 0.07g/cm3, Liquid: ☰.7g/cm3 A vibrating tuning fork liquid level switch is an instrument for monitoring the height of a liquid and tripping a relay contact switch or transmitting a solid state relay switch output when a maximum, minimum or intermediate level has been reached. The working principle of vibrating fork level switch is based on tuning forks natural frequency measurement.
Signal output: Relay, SPDT, 5A/250Vac/ 28Vdc It has no moving parts, needs no calibration and is virtually unaffected by process conditions. 3rdparty IEC61508 (SIL2) safety and hygienic certification with choice of outputs makes it suitable for a wide range of applications. The Rosemount 2120 Level Switch provides easy to install, reliable level detection and control. Supply Voltage and Output: 20~250Vac/Vdc,50/60Hz, Relay SPDT 5A/250Vac / 28Vdc Rosemount 2120 Level Switch - Vibrating Fork. When the measured medium comes into contact with the tuning fork, it will change the feedback resonant frequency due to the damping resonances between the exciting PZT and receiving PZT.īy detecting the frequency and appropriately tuning the sensitivity of tuning fork level switch on measured material, such device can easily operate for monitoring the alarm level of measured material. If the vibrating probe comes into contact with the. Typical applications are overfill or dry run protection. The basis of point level detection with vibrating level switches is a tuning fork, i.e. The tuning fork level switchs oscillation dampens as the material level rises and comes into contact with the tines of the vibrating fork. It is designed for industrial use in all areas of process technology and can be used in liquids. The Type 8110 is a filling level switch for liquids, using a tuning fork as the sensor element. Description The tuning fork level switch is a mechanical resonant device which is excited by piezoelectric (PZT) elements. Level Measurement Using Vibrating Tuning Fork - 555294 from Burkert Fluid Control Systems. Tuning Fork level switches are sensors with an electrical contact output at a specific level.
