VEGA VEGASWING 51 Vibrating Level Switch

Fits point level detection (empty/full, overfill, dry-run, pump protection) on liquids where a short 38 mm vibrating fork and transistor or IO-Link switching are enough — independent of foam, viscosity, and composition within the published limits.

Key advantages

• Short 38 mm fork — compact vibronic point level with ~2 mm vertical hysteresis.
• Media independence — switching largely independent of foam, viscosity, and composition within published limits.
• Output choices — transistor PNP, contactless electronic switch, or IO-Link versions.
• Hygienic / Ex options — stainless 316L wetted parts; Ex, hygienic, and marine approvals by configuration.

Typical applications

• Tank empty/full and overfill protection on thin liquids.
• Pump dry-run protection in compact vessels.
• Hygienic process points needing a short vibrating fork.

Selection guide

• Function / range — Point level detection (empty/full, overfill, dry-run, pump protection); fork length 38 mm; hysteresis approx. 2 mm vertical.
• Accuracy — Millimetre accuracy stated; independent of foam/viscosity/composition (within datasheet limits).
• Media limits — Density 0.7…2.5 g/cm³ (optional 0.5…2.5 g/cm³); viscosity 0.1…10000 mPa·s dynamic.
• Process pressure — −1…+64 bar (−14.5…+928 psig).
• Media / ambient temperature — Standard −40…+100 °C; high-temperature version −40…+150 °C. Ambient −40…+70 °C on housing; storage/transport −40…+80 °C.
• Output — Transistor PNP; contactless electronic switch; IO-Link versions.
• Supply — 9.6…35 V DC; power consumption max 0.5 W; load current <250 mA; switching voltage <34 V DC.
• Process connection — Thread from G½, ½ NPT, hygienic fittings.

Common mistakes

• Using standard density 0.7…2.5 g/cm³ when the liquid needs the optional 0.5…2.5 g/cm³ range.
• Specifying standard −40…+100 °C when process needs the high-temperature −40…+150 °C version.
• Ignoring ambient on the housing (−40…+70 °C) when process is hot but the enclosure sits in a hotter cabinet.
• Ordering PNP transistor electronics when the host expects IO-Link (or the reverse) — electronics option on the order code.
• Claiming a specific Ex / hygienic / marine certificate number from this page — the sheet lists those families generically; request the exact cert with the quote.
• Expecting a continuous level transmitter — this SKU is a point level switch with no display.

When to RFQ / what to tell us

1. Duty: empty/full, overfill, dry-run, or pump protection; mounting orientation.
2. Media density, viscosity, process pressure, and process temperature (std vs high-temp version).
3. Process connection (G½ / ½ NPT / hygienic) and wetted preference (316L).
4. Electronics: PNP transistor vs contactless electronic switch vs IO-Link; available 9.6…35 V DC supply.
5. Ambient on housing, IP need, and which Ex / hygienic / marine marks must appear on the nameplate.
6. Quantity and ship-to country.

FAQ

Q: Continuous level or point switch? A: Point level switch (vibrating fork, 38 mm). Use it for empty/full, overfill, dry-run, or pump protection — not continuous level gauging.

Q: What density and temperature limits apply? A: Density 0.7…2.5 g/cm³ (optional 0.5…2.5); process −40…+100 °C standard or −40…+150 °C high-temp version; pressure −1…+64 bar.

Q: Which approvals can I claim? A: Datasheet lists Ex, hygienic, and marine generically. Ask for the specific certificate numbers you need before ordering — we do not invent cert IDs.

Q: What should I send for a quote? A: Duty, media density/viscosity/T/P, connection, electronics option, required marks, quantity. Compatible with systems using VEGA VEGASWING 51 if you need a drop-in check — we do not claim authorized-dealer status.
