operating conditions

Ambient temperature -15 °C to +60 °C
Air humidity < 80%, non condensated
Protection rating IP65 acc. to EN 60529, female
connector wired, plugged and
tightened
conformity to standards and
directives
The device conforms to the EC directives through the fol-
lowing standards:
• EMC: EN 61000-6-2, EN 61000-6-3
• Vibration: EN 60068-2-6
• Shock: EN 60068-2-27
• Pressure: Article 3§3 of the Pressure Directive 97/23/CE.
Pipe diameter DN20 (except for DN20 specified
p.27) to DN400. The appropriate
diameter is determined using the flow
rate / DN / fluid velocity graphs.
Pressure class Depends on the material of the fitting
used and on the fluid temperature.
See Tab. 1
Fluid temperature The fluid temperature may be restricted
by the fluid pressure: Refer to the
temperature-pressure dependency
curves for the device. See Tab. 1
