Acoustic emission sensors for high temperature areas / 8152C
8152C
Acoustic emission sensors of Type 8152C are applied for measuring acoustic emissions from machine structures.
主要特点/优势
- High sensitivity and wide frequency range
- Inherent high-pass characteristic
- Insensitive to electric and magnetic noise fields
- Robust for industrial use (IP65)
- High operating temperature range
- Ground isolated, prevents ground loops
Type 8152C are acoustic emission (AE) sensors with Piezotron which consist of the sensor housing, the piezoelectric sensing element, and the built-in impedance converter. The sensing element, made of piezoelectric ceramic, is mounted on a thin steel diaphragm. Its construction determines the sensitivity and frequency response of the sensor. The coupling surface of the diaphragm welded into the housing is slightly protruded to measure the AE signals. Thus, a precisely defined coupling force results when mounting. This assures a constant and reproducible coupling for the AE transmission. The sensing element is acoustically isolated from the housing by design and therefore well protected against external noise.
