Housed in prepolarized package, ½ in. Model 378A04 enables test engineers to measure extremely low sound pressure levels. Free-field microphone has built-in filter that ensures sensitivity is stable and accurate between 10 Hz and 16 kHz. Sensor is used with data acquisition systems that provide 4–20 mA of constant current. Using common coaxial cables with BNC connectors, Model 378A04 is suited for measuring appliance noise, electric car sound quality, environmental noise, and cabin noise.

Microphone Preamplifier allows acoustic testing in tight spaces.
2015-02-12 14:31:18| Industrial Newsroom - All News for Today
Used to convert high impedance signal from measurement microphone into low impedance signal, Model 426A13 is designed for ½ in. microphones used to measure frequencies within both infrasound and the human audible range (3 Hz to 20 kHz). Preamplifier electronics fit in 0.94 in. long housing, and overall length (including connectors) of 1.4 in. accommodates space-constrained test environments. Noise floor allows measurements from 15 dBA to 147 dB with appropriate microphone.

Supplied in 1.2 in. long housing, Model 426A07 converts high impedance signal from measurement microphone into low impedance signal. Unit can be paired with any PCB® ¼ in. free-field, random incidence and pressure microphone cartridges to test high frequencies ranging from human audible range of 20 Hz to 20 kHz up to ultrasonic frequencies greater than 100 kHz and high amplitude measurements past human threshold of pain, up to 194 dB.

Suited for remote sound level measurement, Model PRM2103 operates with Model 831 Sound Level Meter, 377B02 microphone, and environmental shroud for portable or permanent outdoor use in wide range of weather conditions. Automatic calibration checks 5 different frequencies simultaneously, enabling detection of any failure. When used with sound level meter, acoustic response can be selected as free-field, random, or 90° using setting on meter. This story is related to the following:Preamplifiers
