Accessories for WIKA / KSR Kuebler Level Instrumentation – mounting, protection & integration
Accessories complete and optimize bypass indicators, float transmitters and point level switches from WIKA / KSR Kuebler: from floats, guide tubes, clip-on limit switches and transmitters to process adapters, heating/insulation, rinse/wiper units, luminaires, scales, plus junction boxes, Ex barriers, power supplies and pre-made cable sets.
Depending on the application you can choose hygienic-design parts (clamp/Varivent), ATEX/IECEx, SIL, IP67–IP69K, seawater/chemical-grade materials and complete material/conformity certificates.
ICS Schneider Messtechnik supports selection, retrofit and integration of accessories—including calibration, proof-test concepts and IIoT connectivity.
FAQ on Accessories for WIKA / KSR Kuebler Level Technology
Answers on floats, switches/transmitters, mounting, cleaning, heating/insulation, electrics, hygiene/ATEX/SIL and documentation.
Which float variants are available?
| Type | Material | Use |
|---|---|---|
| Standard | 316L/1.4404 | Water, oils, many chemicals |
| Corrosion-resistant | Hastelloy®, titanium, duplex | Aggressive media/seawater |
| Hygienic | Polished 316L | Food & pharma (CIP/SIP) |
| Special ρ/viscous | Weighted/slim shapes, PTFE | Low/high density, build-up |
Which limit switches can be retrofitted on a bypass?
Magnetic Reed/Hall switches with clamp brackets, freely positionable along the scale. Outputs PNP/NPN, relay, Namur (Ex i); optional IO-Link.
Are continuous transmitters available as add-ons?
Yes—Reed-chain or magnetostrictive transmitters for bypass/guide tubes with 4–20 mA/HART, Modbus/RS-485 or IO-Link.
What process adapters/connectors are offered?
G/NPT threads, PN/ANSI flanges, clamp/Varivent, weld-in nozzles, reducers, expansion pieces and neck extensions for high temperatures.
What are rinse/wiper units used for?
They keep viewing areas and prisms clear (sight glass/flap indicators). Versions are manual/pneumatic; optional spray nozzles and media ports.
When do I need heating/insulation?
For condensation, crystallization or viscosity control. Options: heater jackets (electric/steam), trace heating on the bypass, and insulation shells with service openings.
Which luminaires are available?
LED luminaires for reflex/transparent gauges and sight cells; IP67/IP69K, optional ATEX, with focused optics for high contrast.
What scales/markings can I add?
mm/cm scales, custom strapping scales, colored min/max markers and UV-stable front scale strips.
Which junction boxes/enclosures are recommended?
IP67–IP69K housings with strain relief, optional dehumidified boxes with desiccant; terminals for 2-/3-/4-wire, M12/circular connectors.
Which Ex barriers/isolators are required?
For Namur/Ex i limit switches and 4–20 mA loops in Zone 0/1 use approved Zener barriers or galvanic isolators per certification and loop resistance.
What power supplies fit best?
24 V DC industrial supplies with EMC certification, optional buffering. For HART ensure adequate loop compliance voltage.
Which cables should I use?
Shielded, twisted signal cables matched to ambient temperature/chemistry; hygienic M12 for washdown; UV-resistant jackets outdoors.
How do I position scales and switches correctly?
Calibrate scales to zero/span, place switches in calm zones, verify function with a test magnet, and document positions.
Which gasket kits make sense as accessories?
| Material | Strength | Typical media |
|---|---|---|
| EPDM | Hot water, some steam | Aqueous |
| FKM | Oils/solvents | Hydrocarbons |
| PTFE | Chemical resistance | Process/chemicals |
| FFKM | Max chemical/high T | Aggressive media |
What options exist for hygienic applications?
Flush adapters, clamp/Varivent, polished surfaces, FDA/EU 1935/2004 gaskets, CIP/SIP-capable lights and wipeable scales.
What accessories suit high T/p service?
Extended necks, cooling sections, high-pressure flanges, mica shields for windows and high-temperature cables/connectors.
Can I retrofit IIoT/diagnostics?
Via IO-Link adapters, HART multiplexers or RS-485/Modbus gateways, including status/alarms and—depending on transmitter—echo/data logs.
What testing and documentation packages are available?
EN 10204 3.1 material certs, pressure/leak tests, DAkkS/factory calibrations, Ex approvals, SIL documentation and FAT per test plan.
Which spare parts are sensible to keep?
Gasket sets, magnetic switches, luminaires, scales, desiccant, cables/connectors and—if applicable—replacement floats matched to density.
Do you support selection and retrofit?
Yes—we review medium/ρ/T/p, define connections, choose switches/transmitters, provide certificates and integrate into PLC/SCADA/cloud—including a commissioning checklist.
