Fine small tuning fork type liquid level switch

Product features:

1), circular smooth single-rod probe, can effectively prevent clamping and sticky material (better than tuning fork type), in more hanging material, still can work stably.

2) It is not affected by the electric parameters of the measured medium (better than capacitive type). After installation, it can be put into stable work without adjustment.

3), the piezoelectric element is placed in the probe of thick stainless steel pipe wall, anti-heavy load, wear resistance, corrosion resistance.

4), can be adjusted according to the material of different density, fine material can also function.

Principle of Action:

The piezoelectric element is used as the driver and the signal feedback to make the probe produce resonance. If the material level contacts the probe, the vibration will stop and a contact signal will be sent out. This product is based on the damping effect generated when the tested object is wrapped in the probe, so that the probe stops resonating, and the output of a switch signal, so there is no signal amplifier circuit inside, which can avoid the trouble caused by the change of material properties and the need to often adjust the sensitivity.

Scope of application:

1), powder body: cement, lime, iron powder, flower fertilizer, washing powder, refined salt, refined sugar, flour, milk powder, etc.

2) Granular body: chemical raw materials, drugs, food, etc.;

3) Block: coal block, limestone ore, etc.; Powder, small particles;

Technical parameters:

1), power supply: AC220VAC 50H or DC24V(wide voltage)

2) Power consumption: less than 1.5W

3), working temperature: instrument part :-40℃~+70℃ probe part :-40℃~ ~+ 150℃

4), starting time: about 3 seconds -- response time: about 1 second

5), output mode: a group of relay output (AC 220V/5A DC 24V/5A)

6) Sensitivity: Press SET to be healthy at this time, LED1 and LED2 will roll and light successively, indicating that the sensitivity is from high to low

7) Mounting interface: 1 "PT tooth (can be customized non-standard mouth and flange connection)

8) Material: Except for the aluminum alloy of the junction box, the other materials are SUS304 (different materials can be customized)
