Vibrating Fork Level Switch to tuning fork by piezoelectric crystal and inherent frequency of tuning fork. It can monitor continuously to the change of frequency. When the Vibrating Fork Level Switch is used for low alarm (or low position control), the medium in the vessel is discharged downward passing through the tuning fork.
When it is lower than the specific location and change the inherent frequency, this change is detected by electronic component, the output state is shifted; When it is used for high alarm (or high position control), the medium in the vessel go upward and contact with tuning Vibrating Switch which can shift the output state. Plenty of researches make the tuning fork technology get the greatest operating efficiency which enable the product apply to any liquid, including coating liquid (eliminate tuning adhesion and joint), aerated liquid, serous fluid and good flow without adhesion of powder. Both occasion which using float liquid lever switch and which cannot use float liquid level switch due to structure, turbulent flow, agitation, air bubble or vibration can use tuning fork level switch.
As Vibrating Fork Level Switch has not moving parts, there is no need to maintain or regulate, it is the advanced product comparatively to float level switch. Vibrating Fork Level Switch is widely used in the field of petrifaction, light industry and water treatment for controlling level and alarming automatically.
19…60VDC 19…250VAC 50/60Hz
In the medium 2 seconds, empty: 3 seconds
Powder and particle =10mm，density>0.1g/cm³
Liquid, viscosity =10000mm2/s, density >0.7g/cm³
Relay, AC250V/4A, DC60V/4A
DC<3W, AC <15W
● Insert the fork into the medium to be measured about 10mm depth, Press the button “SET” until red and greed LEDS blink alternatively for at least 2 times, then release the button “SET”, now red LED blinks, then press the button “SET”, red and greed LEDS blinks alternatively then both on.
● Remove the fork from the medium, green LED on, and red LED off (NC is closed with COM, NO and COM are opened), now insert the fork into the medium again, Both LEDs are ON, (NO is closed with COM, NC and COM are opened). Now setting are finished.
● Default density is set for water: 1g/cm³, If the target medium density ≥ 1g/cm³, Self-Checking is not necessary. Self-Checking is necessary when the target medium density < 1g/cm³.
● Default Sensitivity is the highest, for material that have irregular surface and fluctuate, please set lower Sensitivity.
● Avoid to install in the position that vibrate drastically.
