Point Level Detection – safe min/max monitoring in liquids & bulk solids
Point level switches reliably indicate empty, full or alarm states to prevent dry-run, overfill and product loss. Depending on medium and process, options include vibrating forks, capacitive and conductive probes, optical sensors, floats, rotary paddles (bulk solids), microwave barriers, thermal switches and pressure/diaphragm switches.
Features (model-dependent): hygienic design (EHEDG/FDA), ATEX/IECEx, SIL, proof-test functions, IO-Link/HART, PNP/NPN/relay, fail-safe modes, high IP ratings and robust process connections (clamp, Varivent, G/NPT, flange).
ICS Schneider Messtechnik supports principle selection, materials, installation location, parameterization and PLC/SCADA integration—including calibration and documentation.
FAQ on Point Level Detection
Answers on technologies, media, hygiene/ATEX/SIL, mounting, setup, troubleshooting and best practices.
Which switching principle fits my medium?
| Principle | Media | Strengths | Notes |
|---|---|---|---|
| Vibrating fork | Liquids/bulk solids | Universal, low maintenance | Usually tolerant to foam/build-up (self-monitoring) |
| Capacitive | Liquids/pastes/bulk | Very versatile | Tune sensitivity for product adhesion |
| Conductive | Aqueous media | Robust, economical | Requires minimum conductivity |
| Optical | Clear/clean liquids | Compact, fast | Watch contamination/fogging |
| Float | Liquids | Simple, no setup | Needs mechanical movement/space |
| Rotary paddle | Bulk solids | Proven, rugged | Grain size/density dependent; bearing care |
| Microwave barrier | Bulk, aggressive | Non-contact, through-wall possible | Use suitable window/adaptation |
| Thermal | Gases/liquids | No moving parts | Consider flow/temperature influence |
| Pressure/diaphragm | Pipes/vessels | Simple, direct | Medium/pressure dependent |
What’s the difference between Max, Min and Fail-safe?
Max switches at the upper threshold (overfill protection). Min switches at the lower threshold (dry-run protection). Fail-safe defines behavior on fault (e.g., cable break, device error)—often selectable as de-energized-safe for min or max duty.
How do I choose the right process connection?
Based on pressure/temperature, cleanability and space: G/NPT, clamp/Varivent (hygienic), flange (PN/ANSI). For tanks with agitators, choose reinforced forks/probes.
How do foam and build-up affect switching?
Vibrating forks with auto-adjust and strong excitation are highly tolerant. Capacitive sensors: adjust coupling/sensitivity. Optical sensors: consider heating/rinsing against fogging/fouling.
What repeatability can I expect?
Typically ±2…5 mm for forks/optical. Capacitive depends on medium but can be excellent after teach-in. Bulk devices depend on grain size/density.
Which materials and seals are available?
| Part | Materials | Use |
|---|---|---|
| Wetted parts | 316L, 1.4571, Hastelloy®, titanium, PVDF/PTFE | Chemical, seawater, hygiene |
| Seals | EPDM, FKM, PTFE, FFKM | Media/temperature compatibility |
| Windows (MW barrier) | PTFE, ceramic | Abrasive/corrosive, high T |
Which electrical outputs are supported?
PNP/NPN, relay, Namur (Ex i), 4–20 mA with limit, IO-Link, and in some cases HART. For safety loops use dual-channel evaluation and SIL-certified devices.
How is parameterization/teach-in performed?
Via keys/display or IO-Link/HART: set mode (min/max), sensitivity, on/off delays, window function, fail-safe and medium presets.
Where should I place the switch?
- Min protection: below the pump outlet/suction nozzle, in a calm zone.
- Max protection: keep distance to the roof for cleaning/fork oscillation.
- Bulk solids: away from the fill cone, slightly angled downwards if side-mounted.
How do I handle high temperatures/pressures?
Use high-temperature variants or a neck extension; select pressure rating per datasheet (e.g., up to PN40+). For CIP/SIP choose hygienic, flush designs.
What matters for hygienic design?
Dead-space-free (clamp/Varivent), polished surfaces, EHEDG/FDA seals, flush sensor geometry, CIP/SIP resistance and complete material certificates.
Are ATEX/IECEx & SIL options available?
Yes—devices with Ex i/Ex d and SIL2/3 exist. In hazardous areas use suitable barriers, cabling and bonding; document proof-test intervals.
How robust is operation with changing media (density/εr)?
Vibrating forks are largely density independent. Capacitive switches may need a second recipe/auto-adjust. Conductive probes depend on conductivity—observe limits.
How do I avoid false trips from turbulence/flow?
Enable delays (e.g., 0.5–2 s), use a stilling tube, mount away from inlets, and align forks across the main flow.
What cabling/IP ratings are typical?
IP65…IP69K depending on model; use glands with strain relief. For washdown areas, select IP69K/hygienic connectors.
Can I use window/two-point control?
Yes—many electronics offer a window function (two setpoints) for band control; alternatively use two devices for fill/drain control.
How are devices proof-tested?
Via test magnet, pushbutton or simulation mode (type-dependent). Set intervals per SIL verification and record results.
Typical pitfalls & quick fixes
- Wrong mode (min/max) → check parameterization
- Fouling/crust → cleaning interval, choose flush design
- EMC coupling → shielded wiring, equipotential bonding
- Poor mounting point → avoid inlets/flow, add calming
- Low conductivity (conductive) → select another principle
How do I integrate switches into control systems?
Use digital inputs for PNP/NPN/relay, IO-Link for parameterization/diagnostics; evaluate heartbeats/alarms. Implement fail-safe logic in the PLC.
Do you support selection & commissioning?
Yes. We define setpoints, choose the principle/materials, provide calibration certificates, support hygiene/Ex documentation and integrate into PLC/SCADA/IIoT.
