Knowledge of capacitive and tuning fork level switches

First, capacitive level switch
The capacitive level switch uses anti-adhesive electronics to detect true levels while eliminating the false object signal that sticks and hangs around the probe.
Technical parameters of the capacitive level switch:
Certification: CE, IEC-Ex, ATEX, FM/CSA, GOST Ex, RTN Ex
Temperature: -40 ° C ~ 180 ° C
Pressure: 16bar
Dielectric constant: >1.4
Length: 0~3 meters
Power supply: universal voltage 20..230VAC/19..50VDC
Process connection: thread G 1 1/2"
Sensitivity: adjustable in second gear
Output: DPDT/PNP FSH/FSL adjustable Output delay adjustable
Protection level: IP66
Second, tuning fork type material level switch
The tuning fork level switch is a general-purpose level switch. The tuning fork is excited by the internal crystal excitation. When the tuning fork is covered by the solid material, the vibration frequency changes and is detected by the electronic circuit, thereby outputting a switch quantity for alarm or control purposes. Widely used in petrochemical, metallurgy, light industry, building materials, environmental protection and other industries to achieve the upper and lower limits of the material level alarm and control.
Technical parameters of tuning fork level switch:
Certification: CE, IEC-Ex, ATEX, FM/CSA, GOST Ex, RTN Ex

Length: 0~10 meters
Power supply: universal voltage 20..230VAC/19..50VDC
Process connection: thread R 1 1/2"
Sensitivity: adjustable in second gear
Output: SPDT/DPDT/PNP/NAMUR FSH/FSL adjustable
Protection level: IP66
