Operating conditions (environment)
Ambient temperature limits • 40 to +85°C (–40 to +185°F)
• Onsite display 4 to 20 mA: –30 to +80°C (–22 to +176°F)
• Onsite display 4 to 20 mA HART, PROFIBUS PA: –25 to +70°C (–13 to +158°F)
Lower temperatures minimize the speed and contrast of the display.
!
Note!
For high-temperature applications, either a PMP46/48 with a temperature isolator or with a capillary can be
used. If vibrations also occur in the application, Hauser recommends you use a PMP46/48 with a
capillary.If a PMP46/48 with a temperature isolator or capillary is used, we recommend a suitable bracket for
mounting (see "Wall and pipe-mounting" section on Page 26).
For devices for use in hazardous areas, see Safety Instructions, Installation or Control Drawing (ZDs).

Climate class Class 4K4H (air temperature: –20 to 55°C (–4 to 131°F), relative humidity: 4 to 100%)
fulfilled as per DIN EN 60721-3-4 (condensation possible)
Electromagnetic compatibility • Interference emission as per EN 61326 for class B equipment, interference immunity as per EN 61326
appendix A (industrial use) and NAMUR Recommendation on EMC (NE 21).
• Maximum measured error: < 0.5 % of span (100 mbar sensors: < 1.25% of span)
• In the event of surge influence (EN 61000-4-5), deviations greater than the specified measured error can
occur briefly.
• All measurements were performed with a turn down (TD) = 1:1.
