Classe di protezione: IP68 / IP69K, resistant to high-pressure jet cleaning

Basic accuracy: 0.2% FS; extended display range: 1.5% FS

Vita utile meccanica: ≥100 million pressure cycles

Display: Rotatable housing, electronic analog pointer + LED bar graph for long-distance visibility. Optical touch keys for parameter setting, switch point adjustment, range scaling and peak value hold/reset.

✅ Model Differentiation (Critical for Procurement)

PG2795: G1 Aseptoflex Vario thread, 1 interruttore + uscita analogica, analog pointer display

PI2795: Same -1~4bar range, 2 switching outputs + 4-digit digital screen (no analog pointer)

PG2895: Stessa gamma, G1 conical seal (non-Aseptoflex) versione

✅ Typical Applications

Dairy, beer, fruit juice, sauce, pharmaceutical preparation tanks, static hydrostatic level measurement in hygienic pipelines (vacuum/positive pressure monitoring), CIP circuit pressure control, pressure measurement for viscous media.

✅ Key Requirements for Domestic Alternative Models (for Tender Replacement)

1. Hygienic flush diaphragm, G1 Aseptoflex Vario or compatible hygienic fitting, Ra ≤ 0,4 μm
2. Measuring range -1~4 bar, withstand short-term SIP 145℃, Protezione IP69K
3. 4-20mA analog + 1 PNP/NPN switch output; IO-Link opzionale
4. Wetted part 316L stainless steel, FDA / 3A hygienic certification

IFM PG2795 | M12 4-pin A-coded Pin Assignment

PG2795: Pin4 = OUT1 (Interruttore / IO-Link C/Q); Pin2 = OUT2 (4…20mA analog signal)

Operating Mode Notes:

SIO Mode (Operazione standard): Pin4 = switching output; Pin2 = 4-20mA analog signal

IO-Link Mode: Pin4 serves as C/Q communication line. Switch status and analog value are transmitted via IO-Link telegrams; the hardware analog output (Perno2) remains functional

A-coded connector; 1 PNP/NPN programmable switch + 4-20mA analog. No IO-Link function (IO-Link version belongs to PI27 series)

1. Ripartizione della codifica del modello (PG2795 Decoding)
2. PG = Pressure transmitter with analog gauge display
3. 27 = G1 external flush hygienic thread; 28 = tri-clamp connection
4. 95 = range code: 95 = -1…4 bar
5. Suffix REA01-MFRKG: Aseptoflex seal, flush diaphragm, Connettore M12 a 4 pin
6. Distinzione critica (Avoid Wrong Order)

PG27: Only switch + 4-20mA, NO IO-Link; analog pointer + numeric display

PI27: Same outline, with IO-Link + dual switching outputs + uscita analogica, pure digital 4-segment screen (no mechanical pointer)

1. Phase-out Notice

PG2793 is gradually discontinued; modello sostitutivo: PG1703. All other models (PG2794/95/96/97/98/99) remain in full production.
