Why choose· 01

Built for your duty.

Separate from simple capacitance

RF admittance is worth its own page because buyers use it for coating and buildup problems.

Buildup rejection

Driven shield or admittance circuitry can help ignore stable coating on the probe in suitable applications.

Good retrofit choice

Probe length and connection can be configured for high, low or interface alarm duties.

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.

RF admittance level switches are selected when simple capacitance detection may be affected by coating, sticky media or changing material conditions.

WELK confirms dielectric constant, conductivity, buildup thickness, probe coating, vessel grounding and alarm point before quoting.

RF Admittance 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

RF Admittance Level Switch questions.

How do I choose the switching point for RF Admittance 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 RF Admittance Level Switch and continuous transmitter?

RF Admittance 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 RF Admittance 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 RF Admittance 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.
