Why choose· 01

Built for your duty.

Compact fork size

Mini tuning fork switches fit small tanks, pipe sections and OEM equipment with limited space.

No float travel needed

The vibrating fork detects liquid presence without requiring a large moving float.

Fast point detection

Useful for overflow alarm, dry-run protection and simple interlock points.

Engineer-checked selection

WELK checks medium, alarm height, mounting orientation, connection, output logic, power, contact rating and material requirement so the quoted configuration matches the application.

Application-matched configuration

Selection notes focus on real tank conditions, measuring range, process connection, output signal and installation limits.

Product details· 02

How it is selected & specified.

Compact tuning fork switches are a separate supplier catalog buying category because thread size, fork length and small body dimensions matter to OEM buyers.

WELK confirms liquid density, viscosity, thread, output, power supply and whether the switch is used for high or low alarm.

Compact Tuning Fork Level Switch is presented as a configurable WELK product family. Final model limits, wetted materials, process connection, certificate and output signal are confirmed from the selected datasheet before quotation.

Point level switch selection starts from medium behavior, alarm point, mounting direction, density or dielectric, buildup risk, process connection, power and contact logic.

FAQ· 06

Compact Tuning Fork Level Switch questions.

How do I choose the switching point for Compact Tuning Fork Level Switch?

Start from medium, alarm height, mounting orientation, connection, output logic, power, contact rating and material requirement. WELK then confirms the exact model, material and output before quotation.

What is the difference between Compact Tuning Fork Level Switch and continuous transmitter?

Compact Tuning Fork Level Switch is selected for its specific duty and limitations. WELK compares it with continuous transmitter, radar, ultrasonic when the process data suggests another technology may be safer.

Can Compact Tuning Fork Level Switch be customized?

Yes. Range, process connection, wetted material, output signal, cable length, display, switch points, documents and OEM label can be reviewed by product family.

What are the common limits of Compact Tuning Fork Level Switch?

Sticky buildup, coating, turbulence, low density solids, non-conductive liquids or tank-wall material can make one switch principle unsuitable.

Are the listed specifications final for every project?

No. Published values are typical selection ranges. WELK confirms final limits, material, output, certificate and documents from the actual process data before quotation.
