Proline Promag 300 Modbus RS485 Description of device parameters
Hauser 115
Description Use this function to enter a time constant for the reaction time of the current output signal
to fluctuations in the measured value caused by process conditions.
User entry 0.0 to 999.9 s
Factory setting 1.0 s
Additional information Entry
Use this function to enter a time constant (PT1 element
3)
) for current output damping:
• If a low time constant is entered, the current output reacts particularly quickly to
fluctuating measured variables.
• On the other hand, the current output reacts more slowly if a high time constant is
entered.
Damping is switched off if 0 is entered (factory setting).
Response time
Navigation  Expert → Output → Curr.output 1 to n → Response time (0378–1 to n)
Prerequisite One of the following options is selected in the Assign curr. parameter (→  106):
• Volume flow
• Mass flow
• Correct.vol.flow
• Flow velocity
• Conductivity
*
• CorrConductivity
*
• Temperature
*
• Electronic temp.
One of the following options is selected in the
Current span parameter (→  106):
• 4...20 mA NAMUR
• 4...20 mA US
• 4...20 mA
• 0...20 mA
Description Displays the response time. This specifies how quickly the current output reaches the
measured value change of 63 % of 100 % of the measured value change.
User interface Positive floating-point number
Additional information Description
The response time is made up of the time specified for the following dampings:
• Current output damping →  114
and
• Depending on the measured variable assigned to the output.
