Description
High-level and high-frequency Microphone Set Type 4954-B is delivers great measurement performance, while the laser welded stainless steel diaphragm and a stainless steel protection grid, make this microphone capable of withstanding rough environments.
- High-frequency measurements
- High-level measurements
- Cost-effective measurements
CAPIBILITIES
- Excellent amplitude and phase matching over wide ranges of temperature and humidity phase response
- Excellent long-term stability through artificial aging and clean room assembly guarantee excellent long-term stability and low noise even in harsh environments
- Side vented for pressure equalization.
- The microphone does not need an external polarization voltage, thus enabling the use of inexpensive 2-wire system (CCLD) input.
Prepolarized Free-field Microphone Type 4954 has been optimised for a flat, free-field response and is suited for measurements far beyond the audible range. Due to its wide frequency range, the frequency response in the audible range is typically within ±1 dB.
