1/4" Free Field Microphone With CCLD Preamplifier, Prepolarized

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.

USE SCENARIOS

• High-frequency measurements
• High-level measurements
• Cost-effective measurements

This microphone consists of Microphone Type 4954 laser welded to a ¼" microphone preamplifier. The unit is assembled in a clean-room environment and sealed together, after which it is assigned one single type number and one single serial number. This means that the combined unit has better precision and long-time stability, and is handled as one complete unit.

The transducers can be connected to any CCLD input and support IEEE P1451.4 V0.9 TEDS (Transducer Electronic Data Sheet). The unit also contains TEDS, which means that information about the serial number, type and sensitivity is stored within it.

BENEFITS OF USING A MICROPHONE-PREAMPLIFIER SET:

• Better stability and precision. Because the unit is assembled in clean-room facilities, there is no contamination.
• Ease of use. Your analyzer front-end and software will automatically detect the type number, serial number and sensitivity because of the built-in TEDS technology. There is no need to enter this manually for every channel. 
• Calibration integration. The TEDS technology means the microphone is automatically detected and identified by your data acquisition software, allowing it to be easily integrated with your calibration database.
• Fewer errors. As your data acquisition software automatically knows the microphone type, serial number and sensitivity, manual inputs are greatly reduced – reducing human errors.
