"Diagnostic factor"
Diagnostic of the factors located during the Teach-In. No default setting.
"W-Diagnostics"
Diagnostics of the measuring values for NF material type. No default setting.
"UDK20-PR-S-(1)"
"SV:xx HV:xx"
Unit identification. Keep this information available for telephone support.
"Bus diagnostic"
Viewing of the process data. Helpful for commissioning on Field bus connected.
3.4.2 Program parameters
The sensor is operated in two different modes. For FE material an electro magnetical method –
called "P" measurement – is used.
For the P measurement a compensation curve for linearization exists.
The compensation curve fits to ST37 steel. Other steel alloys resp. magnetical materials deviate
from this curve. This causes measuring results which can deviate for more than 5% from the real
sheet thickness. In such cases it is useful to calibrate the unit (later merely called "Teach-In").
For NF material an eddy current method – called "W" measurement – is used. Here a Teach-In is
required, since there is no general linearization curve.
In order to avoid frequent Teach-In procedures for different materials and thicknesses, the unit
provides for 255 program memories. Every such memory consists of a data set with the following
parameters.
"Sensor number"
For multi-channel systems (e.g. UDK20-2PW...) or a system with external sensor switch box
SSBUDK10 the selected sensor must be entered.
"Material"
Selects the material type FE, NF or LM (slightly magnetical stainless steels). In case of unknown
material AUTO must be chosen. For all settings (except for FE) a Teach-In is required.
"Nominal thickness"
Changes the nominal thickness. It can be shown in mm or inch.
Default setting either 0,03mm or 0,001 inch.
