Key parameters
Measuring range
0…250 bar relative pressure
Accuracy
< ±0.25% span BFSL / < ±0.5% LS
Output
4…20 mA analog
Supply
9.6…32 VDC
Process connection
G 1/4 external / M5 internal (DIN 3869-14 FPM seal)
Ambient temperature
−25…80 °C
Fits relative pressure to 250 bar with external thread where you need an ifm PA3521 ceramic-cell transmitter, 4–20 mA output, and G 1/4 external / M5 internal process connection.
Key advantages
- Range — 0…250 bar relative
- Output — 4…20 mA; supply 9.6…32 VDC
- Accuracy — < ±0.25% span BFSL / < ±0.5% LS
- Connection — G 1/4 external / M5 internal (DIN 3869-14 FPM seal)
- Rating — 400 bar; min. burst 850 bar; ceramic measuring cell
Typical applications
- Hydraulic relative pressure with external G 1/4.
- Machine builders preferring PA35xx thread style.
- Liquid (and gas — contact ifm above 25 bar gas).
Selection guide
- Thread style — External PA3521 vs internal PA3021
- Range — 250 bar
- Media — Liquids; gases >25 bar contact ifm
- Temperature — −25…90 °C medium
Common mistakes
- Ordering internal-thread PA3021 when external is required.
- Gas service above 25 bar without ifm confirmation.
- Wrong seal (FPM) for media.
When to RFQ / what to tell us
- Media, P, T; thread preference; quantity; ship-to.
