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 0.8 m (2.62 ft): max.
±4 mm (±0.16 in)
±0.03 %
Measuring distance > 0.8 m (2.62 ft): ±1 mm (±0.04 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.
Differing values in near-range applications
A0032636
8 Maximum measured error in near-range applications
Δ Maximum measured error
R Reference point of the distance measurement
D Distance from reference point of antenna
Measured value resolution
Dead band according to DIN EN IEC 61298-2 / DIN EN IEC 60770-1:
• Digital: 1 mm
• Analog: 1 µA
Response time
The response time can be configured. The following step response times (in accordance with
DIN EN IEC 61298-2 / DIN EN IEC 60770-1)
2)
are when damping is switched off:
2) According to DIN EN IEC 61298-2 / DIN EN IEC 60770-1, the step response time is the time that elapses after an abrupt change in the input
signal until the change in the output signal has adopted 90% of the steady-state value for the first time.
