Damping buildup (TAU)
Damping conductivity (TAU)
Navigation
Application → Sensor → Damping buildup (TAU)
Application → Sensor → Damping conductivity (TAU)
Description
The parameter affects the display of the measured value with a time lag according to the
behavior of a PT
1
element. A TAU corresponds to 63.2 % of the expected measured value.
The measured value is reached after 5 TAU.
Switch-on value
As set in the device.
Input range
0.1 to 60.0 s
Factory setting
2 s
Note
The damping setting can be ordered as a preset value in the product structure via order
code 570 "Service", option HS "Damping setting to spec.".
DC-Media
Navigation
Application → Sensor → DC-Media
Note
The dielectric constant can be ordered as preset to 2.7 in the product structure via order
code 570 "Service", option HT "Configuration output 1 + output 2".
Description
For applications with non-conductive media, the preset value for the dielectric constant
can be adjusted or changed to the value of the current medium. The dielectric constant
value is used as a multiplier for calculating the buildup of non-conductive media.
Input range
1.5 to 85
Factory setting
13
Calibrate buildup zero (GTZ)
Navigation
Application → Sensor → Calibrate buildup zero (GTZ)
Note
Only perform this function when the installation is empty.
Description
Permanent buildup which is not relevant can be automatically suppressed with this
function. The value determined is applied to the "Offset buildup" parameter.
Options
Set Zero
Empty
Offset buildup
