Endress+Hauser Micropilot FMR67 - Influence of Ambient Temperature; Response Time

Micropilot FMR67
24 V. 1, Rev. 3, 11-04-2017 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)
2)
are when damping is switched off:
Sampling rate
≥1.3 s
–1
at U
≥ 24 V
Response time < 3.6 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
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
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.
