Product overview 

As for the tuning fork level switch, the signal of the electronic circuit is used to excite the crystals in the fork so that the fork of a tuning fork vibrates at a fixed frequency. When the fork body is completely immersed by the measured material and the vibration frequency of fork body changes, the electronic circuit of the instrument will automatically detect the change and convert it into a switching signal to be output by a relay for on-site alarm or remote control; When the material leaves the fork body, the instrument will return to normal working condition and continue to detect changes in material level.
