Reaction time
The reaction time can be parametrized. The following step response times (as per DIN EN
61298-2)
3)
are valid if the damping is switched off:
Level measurement
Probe length Sampling rate Step response time
< 10 m (33 ft) 3.6 measurements/second < 0.8 s
< 40 m (131 ft) ≥ 2.7 measurements/second < 1 s
Influence of ambient
temperature
The measurements are carried out in accordance with EN 61298-3
• digital (HART, PROFIBUS PA, FOUNDATION Fieldbus): average T
K
= 0.6 mm/10 K
For devices with remote sensor
4)
there is an additional offset of ±0.3 mm/10K (±0.01 in/10K) per
1 m (3.3 ft) of the remote cable.
• analog (current output):
– zero point (4 mA): average T
K
= 0.02 %/10 K
– span (20 mA): average T
K
= 0.05 %/10 K
3) According to DIN EN 61209-2 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.
