Fluid conditions
7.3.1
Fluid temperature ranges
without limit switch
-20 °C to + 100 °C
with limit switch
-20 °C to + 70 °C
Risk of breakage due to frost
7.3.2
Fluid pressure limit
16 bar (at 20 °C)
Important!
All pressure values refer to non-hazardous liquids and for devices installed free from strain.
For K09-…V/N, the maximum unilateral pressure resistance of the diaphragm is 7 bar.
7.3.3
Inlet and outlet sections
Inlet and outlet sections are not required for a linear flow profile of the fluid.
7.3.4
Physical state
Liquid or gaseous
7.3.5
Pressure for gas measurement
The measured values only apply to the calibrated fluid data stated on the scale. Any change or deviation in
pressure will cause an indication fault.
7.3.6
Pressure loss
Dependant on the measuring range.
