Device
User manual of PCE-USC 30 portable eddy current flaw detector (hereinafter
referred to as "Flaw detector"), is intended for the study of operation
principles of the flaw detector and its operating instructions, and includes the
information on application, specifications, operating principle and structure,
operating instruction, and also other information allowing a full-scale
implementation of flaw detector technical capabilities.
The flaw detector is intended for manual and mechanized testing by
eddy current method for the presence of surface and subsurface
defects, such as material discontinuity (cracks, laps, cissings, fine
cracks etc.), for conductivity and thickness measurement.
The flaw detector can be applied for the testing of products during
their manufacture and operation by NDT services and laboratories of
enterprises that provide the products quality control.
The parameters of testing objects, which limit the flaw detector
application area, are specified in regulatory documents for a specific
type of testing products and materials.
The flaw detector provides the possibility of connecting and
operating ECP of the following types:
- differential ECP;
- differential ECP, connected by the bridge circuit;
- differential transformer ECP with center-point earth;
- differential transformer ECP;
- single (parametric) ECP;
- single transformer ECP.
The evaluation of resistance of the flaw detector and ECP
functioning quality to the impact of electromagnetic interferences of
"В" criterion according to
