Alpheus THT
This sensor is designed for use in harsh environments, offering both high sensitivity and high frequency response. It is fully calibrated for sensitivity and bandwidth. Its compact size makes it ideal for studying high-frequency acoustic waves in pipelines.
**Typical applications include:**
- Turbine analysis (compressor stall analysis)
- Non-destructive testing
- High-voltage measurements (overhead lines, electrical transformers)
- Arc or high-frequency welding processes
- Measurements in ATEX environments
