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)
1)
are when damping is switched off:
Tank height Sampling rate 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 performed according to DIN EN IEC 61298-3 / DIN EN IEC 60770-1
• Digital (HART, PROFIBUS PA, FOUNDATION Fieldbus):
• Standard version: average T
C
= 2 mm/10 K
• Version with advanced dynamics: average T
C
= 3 mm/10 K
• Analog (current output):
• Zero point (4 mA): average T
C
= 0.02 %/10 K
• Span (20 mA): average T
C
= 0.05 %/10 K
1) 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.
