Description: Tuning Fork Level Switch is widely used in the industrial field, it is not afraid of hanging material, not afraid of the impact of high sensitivity. It uses "resonance" principle, produce vibrations in the driving piezoelectric element only when the probe is surrounded by the material, only the vibration amplitude decreases sharply, resulting in the switching operation. How it works: fork rod driven by the piezoelectric wafer and from wafer to receive another piezoelectric vibration signal, the vibration signal to cycle, and the sensor bar to resonate. When the material in contact with the sensor bar, vibration signal becomes smaller until it stops resonance, the control circuit outputs an electrical signal contacts. Features: 1, adaptable: Different electrical parameters measured material, bubbles, vibration, density measurements are not affected. 2, maintenance-free: Since the detection process tuning fork level switch is completed by an electronic circuit, no moving parts, so one does not need maintenance once installed and put into use. 3, does not require tuning: the influence of electrical parameters and measured medium density tuning fork level switch is not detected, so no matter what the measurement of liquids, solids do not need to live *. Technical parameters: 1, threaded connection: 3/4 "NPT 2, supply voltage: DC24V 3, Working temperature: -30--80 degree 4, Power: 3W 5, output: relay output
