Blister Detection

- In-line Blister Detection for profile wire


Blisters are bulgy defects on the surface of the insulation layer that typically occur due to faults in the production processes, and DSE Test Solution A/S offers two types of inline blister detection solutions:

  • BDU - Blister Detection Unit

  • BMS - Blister Measurement System

Blister Detection Unit - BDU

The Blister Detection Unit is a high precision non-destructive device made for detection of blisters in flat enamelled wire during manufacturing and detects blisters on all 4 sides of the wire down to 50μm.In case of a blister is detected the data is stored either local or on a server.

Check out the datasheet for further information on the Blister Detection Unit here

Blister Detection Unit

Blister Measurement System - BMS

If additional information and evaluation on the specific blisters is required (e.g., requirements from the automotive industry and other demanding applications) we can offer the Blister Measuring System.
Besides counting the number of blisters and storing the data as the Blister Detection Unit, this solution detects blisters on all 4 sides of the wire down to 30μm.
Furthermore, it measures the actual height and length of the blisters with the possibility to make a threshold level of the blister size and generate related alarms.

The datasheet for the Blistering Measuring System solution can be found here.

Quality check of the wire

Both the BDU and the BMS solutions can operate as independent standalone inline blister detection solutions and provide the necessary documentation on the quality of the wire.

To provide a complete quality check of the wire, both solutions can be combined with our High Voltage Continuity solution for detection of pin holes and weak spots in the wire insulation.
