Principle
It is a field mounting instrument consisted by tuning fork and electronic box. Communication emitting part: to fix 2 groups of piezocrystal at tip end of tuning fork, one group is a drive element to drive tuning fork producing vibration, another group is a detecting element to change fork vibration into voltage. While both of them are connected with input and output of amplifier in electric box separately, it forms a mechanical —electronic oscillating electric.
When tuning fork is barred , amplitude of vibrator will be getting small, relay is coupling , then terminal will be transfer a switch signal and 0mA current(current output is less than 1mA and more than 0mA).
When tuning fork is non barred , amplitude of vibrator is getting strong, relay is releasing, then terminal will be transfer a switch signal and 10mA current(current output is more than 10mA and less than 11mA).
