![]() ![]() Minimum material density sensed: Solid: >/= 0.07g/cm3, Liquid: ☰. Signal output: Relay, SPDT, 5A/250Vac/ 28Vdc Supply Voltage and Output: 20~250Vac/Vdc,50/60Hz, Relay SPDT 5A/250Vac / 28Vdc Changes to the oscillationfrequency are continuously monitored by electronics as it varies depending on the liquid medium in which the forks are immersed.The denser the liquid, the lower the oscillation frequency. 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. Using the principle of a tuning fork, a piezo-electric crystal oscillates the forks at their natural frequency. ![]() Description The tuning fork level switch is a mechanical resonant device which is excited by piezoelectric (PZT) elements. An electronic circuit continuously excites the tuning fork, causing it to mechanically vibrate. ![]()
