E+H Soliphant FTM20 Level Switch

Fits fine-grained bulk-solids point level where a compact vibronic fork is specified — bulk density ≥200 g/l (not fluidized), grain size ≤25 mm, medium to +150 °C, −1 to 25 bar, with FEM22 DC-PNP or FEM24 relay electronics.

Key advantages

Solids duty — Vibronic point level for fine-grained solids; measuring range depends on installation; grain size ≤25 mm.
Density — ≥200 g/l (not fluidized); density switch 200/400 g/l.
T / P — Medium temperature up to +150 °C (+302 °F) per TI ambient/medium derating chart; ambient −40 to 70 °C; −1 to 25 bar (−14.5 to 362.5 psi); MWP 25 bar; burst 100 bar.
Outputs — FEM22 DC-PNP 3-wire (10–45 V DC); FEM24 relay options; MIN/MAX safety modes.
Protection — IP66/IP67, NEMA 4X; wetted 316L sensor.

Typical applications

Silo and hopper high/low detection for fine-grained solids (≥200 g/l).
Compact thread or Clamp 2" mounts with 316L sensor and polyester F16 housing options.
Dust ignition-proof (DIP) points with FEM22/FEM24 options.
MIN/MAX safety-mode switching on DC-PNP or relay inserts.

Selection guide

Density switch — 200/400 g/l settings; product must not be fluidized.
Electronics — FEM22 DC-PNP 3-wire (10–45 V DC) vs FEM24 relay — lock supply and contact type.
Connection — Thread R 1 / R 1½ / NPT 1¼ / NPT 1½; Clamp 2"; polyester housing F16 options.
Frequency — Operating vibronic 700 to 800 Hz vibronic.
Approvals — Dust ignition-proof DIP (FEM22/FEM24 options); IEC 61010.

Common mistakes

Using liquid Liquiphant assumptions — FTM20 is for fine-grained solids ≥200 g/l, grain ≤25 mm.
Applying to fluidized product — OEM density rating excludes fluidized bulk.
Ordering FTM51 extension lengths when compact FTM20 covers the mount — FTM51 is the long-pipe/high-T family.
Leaving FEM22 vs FEM24 blank — changes supply (10–45 V DC PNP vs relay) and DIP options.

When to RFQ / what to tell us

Bulk density, grain size, fluidized yes/no, and media T/P.
Process connection (R/NPT/Clamp), FEM22 vs FEM24, DIP need.
Quantity, ship-to, MIN/MAX safety mode preference.

FAQ

Q: FTM20 vs FTM51? A: FTM20 is the compact Soliphant T for fine-grained solids ≥200 g/l to +150 °C. FTM51 is the extended-pipe family (from 10 g/l, to +280 °C) — pick by density, length, and temperature.

Q: Min bulk density? A: ≥200 g/l (not fluidized); density switch settings 200/400 g/l.

Q: What should I send for a quote? A: Density, grain size, connection, FEM insert, T/P, quantity. Compatible with systems using E+H Soliphant FTM20 — we do not claim authorized-dealer status.
