Mechanical load • Protect the transmitter housing against mechanical effects, such as shock or impact; the
use of the remote version is sometimes preferable.
• Never use the transmitter housing as a ladder or climbing aid.
Electromagnetic
compatibility (EMC)
• As per IEC/EN 61326 and NAMUR Recommendation 21 (NE 21)
• Complies with emission limits for industry as per EN 55011 (Class A)
• Device version with PROFIBUS DP: Complies with emission limits for industry as per EN
50170 Volume 2, IEC 61784
The following applies for PROFIBUS DP: If baud rates > 1.5 MBaud an EMC cable
entry must be used and the cable shield must continue as far as the terminal wherever
possible.
For details refer to the Declaration of Conformity.
16.9 Process
Medium temperature range • 0 to +80 °C (+32 to +176 °F) for hard rubber, DN 350 to 2400 (14 to 90")
• –20 to +50 °C (–4 to +122 °F) for polyurethane, DN 50 to 1200 (2 to 48")
• –20 to +90 °C (–4 to +194 °F) for PTFE, DN 50 to 300 (2 to 12")
Conductivity ≥ 5 μS/cm for liquids in general
Note that in the case of the remote version, the requisite minimum conductivity also
depends on the cable length .
