Sensors
Barkhausen noise sensors are available in many different types, shapes and sizes, as contact or non-contact types.

General features of the sensors are defined in sensor type number. The sensor type number only specifies the general features of the sensor, not the dimensions and appearance.
Number of the channels
One sensor can have 1-4 channels, or there can be multiple one-channel sensors in one frame. Contact Stresstech for more channel options.

Measurement direction
Sensor measurement direction (orientation) is determined by the magnetization direction. The sample characteristics are representative of the measurement direction.
1 – General, SX-XX-1X-YYYYYY
2 – Axial, SX-1X-1X-YYYYYY
3 –Circumferential, SX-XX-3X-YYYYYY
4 –Point, SX-XX-4X-YYYYYY
5 –Biaxial, SX-XX-5X-YYYYYY
Measurement branch
Measurement branch determines a measurement technology the sensor uses.
1 – Passive (no longer available), SX-XX-X1-YYYYYY
- Compatible with Barkhausen noise analyzer Rollscan 200
2 – Active normal band, SX-XX-X2-YYYYYY
- Compatible with Barkhausen noise analyzers Rollscan 250, 300, 320 and 350
- Optimized for 70–200 kHz analyzing frequency
