Measured value resolution
Dead band as per EN61298-2:
• Digital: 1 mm (0.04 in)
• Analog: 4 µA
Response time
The response time can be configured. The following step response times apply (in accordance with
DIN EN 61298-2) when damping is switched off:
Tank height
<5 m (16 ft)
Sampling rate
1 s
-1
Response time
<3 s
In accordance with DIN EN 61298-2, the step response time is the time following an abrupt
change in the input signal up until the changed output signal has adopted 90% of the steady-
state value for the first time.
Influence of ambient
temperature
The measurements are carried out in accordance with EN 61298-3.
