Measurement Microphones

Model 377A14 is recommended for applications where high amplitude sound pressure levels or high frequency measurements are required. This ¼” model is designed to be used in a flush mounted application where large differences of static pressure exist. Read more...

The Models 765M20 and 765M22 High Intensity Acoustic Sensors (Microphones) are designed for the measurement of gas-borne sound in industrial applications. These sensors have been constructed for use in corrosive environments that are compatible with the type 316 stainless steel diaphragm. The miniature 10-32 fused-glass coaxial connector, when combined with allwelded construction, provid... Read more...

COLUMBIA's Models 765M25 and 765M27 are High Intensity Acoustic Sensors (Microphones) designed for measurement of gas-borne sound in frequency range of 100Hz to 30KHz, in industrial applications requiring operation up to +500 degrees F. Read more...

The Columbia Model 100-P High Intensity Acoustic Sensor (Microphone) is designed for measuring exceptionally wide pressure ranges in applications requiring fast rise times and broad frequency response. This sensor is extremely sensitive allowing very low pressure measurements to 0.005 psi as well as high pressure transient measurements to 5,000 psi at temperatures up to +150 Degrees C. ...

There are a number of models and choices when deciding to purchase a system to measure noise. In some cases multiple microphone and preamplifier models will do the job for the same application. The following information will help you choose the system that will work best for the application. For additional information please download the PCB Microphone Handbook. Read more...

Prepolarized microphones were designed a few decades after their counterpart the traditional externally polarized microphones were developed. Prepolarized microphones have many advantages over the externally polarized models. This design utilizes power circuitry that PCB® invented for sensors, ICP® power. Read more...

PCB® is proud to introduce the Industry Exclusive Model HT378B02. The preamplifier was designed with the microphone in mind. Not just to work with the microphone, but to complement it. This microphone and preamplifier combination can be operated in +250ºF / +120 ºC applications. Read more...

Prepolarized microphones have many advantages over externally polarized models. This design utilizes ICP® power, circuitry that PCB® originally invented for sensors. Read more...
