Endress+Hauser Micropilot FMR56 - Influence of Ambient Temperature

Micropilot FMR56, FMR57
32 Endress+Hauser
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
< 70 m (230 ft) ≥2.2 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): 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.
