Micropilot FMR20
Endress+Hauser V. 5, Rev. 3, 20-12-2016 15
Response time
The response time can be configured. The following step response times (as per DIN EN 61298-2)
1)
apply if the damping is switched off:
Tank height Sampling rate Response time
< 20 m (66 ft) 1 s
-1
< 3 s
Influence of ambient
temperature
The measurements are carried out in accordance with EN 61298-3.
• Digital (HART, Bluetooth® wireless technology):
Standard version: average T
K
= ± 3 mm (0.12 in)/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 61298-2 the step response time is the time which passes after a sudden change of the input signal until the output signal
assumes 90% of the steady-state value for the first time.
