Performance characteristics

• Temperature = +20 °C ±5 °C
• Pressure = 1013 mbar abs. ±20 mbar
• Relative humidity (air) = 65 % ±20 %
• Metallic tank, no internals, distance to tank wall > 500 mm
• Medium: water (DC > 7), respectively oil (DC = 2)
• Probe length > 500 mm
Typical statements for reference conditions:
DIN EN 61298-2, percentage of the span.
Output:
sum of non-linearity,
non-repeatability and hysteresis
Offset / Zero
If the reference conditions are not met, the offset/zero arising from the installation setup may be up to
±12 mm. This additional offset/zero can be compensated for by entering a correction (function "offset"
(057)) during commissioning.
Differing from this, the following measuring error is present in the vicinity of the upper and lower
probe end:
