✅ 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)
- Hygienic flush diaphragm, G1 Aseptoflex Vario or compatible hygienic fitting, Ra≤0.4 μm
- Measuring range -1~4 bar, withstand short-term SIP 145℃, IP69K protection
- 4-20mA analog + 1 PNP/NPN switch output; IO-Link optional
- Wetted part 316L stainless steel, FDA / 3A hygienic certification
IFM PG2795 | M12 4-pin A-coded Pin Assignment
PG2795: Pin4 = OUT1 (Switch / IO-Link C/Q); Pin2 = OUT2 (4…20mA analog signal)
| M12 Pin | Signal | Description |
| Pin1 | L+ / 24VDC+ | Power positive, 18~32VDC |
| Pin2 | OUT2 | 4-20mA analog output (configurable reverse 20-4mA) |
| Pin3 | L- / 0V | Power negative, GND |
| Pin4 | OUT1 / C/Q | Programmable PNP/NPN switch; IO‑Link mode: communication line |
Operating Mode Notes:
SIO Mode (Standard Operation): 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 (Pin2) remains functional
A-coded connector; 1 PNP/NPN programmable switch + 4-20mA analog. No IO-Link function (IO-Link version belongs to PI27 series)

III. PG28 Equivalent Models (Tri-Clamp Version for Direct Replacement)
PG27 = G1 external thread; PG28 = hygienic tri-clamp fitting, ranges fully matched:
PG2793 ↔ PG2893
PG2794 ↔ PG2894
PG2795 ↔ PG2895
PG2796 ↔ PG2896

- Model Coding Breakdown (PG2795 Decoding)
- PG = Pressure transmitter with analog gauge display
- 27 = G1 external flush hygienic thread; 28 = tri-clamp connection
- 95 = range code: 95 = -1…4 bar
- Suffix REA01-MFRKG: Aseptoflex seal, flush diaphragm, M12 4-pin connector
- Critical Distinction (Avoid Wrong Order)
PG27: Only switch + 4-20mA, NO IO-Link; analog pointer + numeric display
PI27: Same outline, with IO-Link + dual switching outputs + analog output, pure digital 4-segment screen (no mechanical pointer)
- Phase-out Notice
PG2793 is gradually discontinued; replacement model: PG1703. All other models (PG2794/95/96/97/98/99) remain in full production.
