Performance characteristics
Reference operating
conditions
•
Temperature = +24 °C (+75 °F) 5 °C (9 °F)
• Pressure = 960 mbar abs. (14 psia) 100 mbar (1.45 psi)
• Humidity = 60 % 15 %
• Reflector: metal plate with diameter ≥ 1 m (40 in)
• No major interference reflections inside the signal beam
Reference accuracy
Typical data under reference operating conditions:
DIN EN IEC 61298-2 / DIN EN IEC 60770-1;
percentage values in relation to the span.
Output: digital analog
1)
Accuracy (Sum of non-
linearity, nonrepeatability
and hysteresis)
2)
Measuring distance up to 1.5 m (4.92 ft): max. 20 mm (0.79 in) 0.02 %
Measuring distance > 1.5 m (4.92 ft): 3 mm (0.12 in) 0.02 %
Non-repeatability
3)
≤ 1 mm (0.04 in)
1) Add error of the analogous value to the digital value.
2)
If the reference conditions are not met, the offset/zero point arising from the mounting conditions may be
up to ±4 mm (0.16 in). This additional offset/zero point can be compensated for by entering a correction
(parameter "level correction") during commissioning.
3) The non-repeatability is already considered in the accuracy.
