Why choose· 01

Built for your duty.

Versatile media coverage

Capacitance switches can detect liquids, slurries, foam, interfaces and some solids when dielectric conditions are suitable.

Probe length options

Rod and cable probes allow switching points away from the vessel wall or roof.

Buildup compensation

RF admittance or sensitivity tuning can help reject stable coating on the probe in suitable designs.

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 capacitance level switches detect level by measuring the capacitance change between the probe and vessel or reference electrode.

Correct selection requires dielectric constant, buildup behavior, conductivity, vessel material, probe length and process connection.

RF Capacitance 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 Capacitance Level Switch questions.

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

RF Capacitance 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 Capacitance 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 Capacitance 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.
