 17 Maximum measured error in near-range applications; values for version with the "Advanced dynamics"
application package
∆ Maximum measured error
A Lower edge of the antenna
D Distance from the lower edge A of the antenna
R Reference point of the distance measurement
Measured value resolution
Dead band according to DIN EN IEC 61298-2 / DIN EN IEC 60770-1:
• digital: 1 mm
• analog: 1 μA
Reaction time
The reaction time can be parametrized. The following step response times (as per DIN EN IEC
61298-2 / DIN EN IEC 60770-1)
1)
are valid if the damping is switched off:
Tank height Sampling rate Step response time
< 10 m (33 ft) ≥ 3.6 s
–1
< 0.8 s
< 40 m (132 ft) ≥ 2.7 s
–1
< 1 s
Influence of ambient
temperature
The measurements are carried out in accordance with DIN EN IEC 61298-3 / DIN EN IEC
60770-1
• Digital (HART, PROFIBUS PA, FOUNDATION Fieldbus):
• Standard version: average T
K
= 2 mm/10 K
• Version with advanced dynamics
2)
: average T
K
= 3 mm/10 K
• Analog (current output):
• zero point (4 mA): average T
K
= 0.02 %/10 K
• span (20 mA): average T
K
= 0.05 %/10 K
1) According to DIN EN IEC 61298-2 / DIN EN IEC 60770-1 the response time is the time which passes after a sudden change of the input signal
until the output signal for the first time assumes 90% of the steady-state value.
