USB DAQ - Universal DAQ

USB Audio Interface 32 Bit DAQ DC - 120 kHz - IEPE Sensor Supply

In this presentation, I demonstrate the use of the free FFT analysis software “Visual Analyzer” in conjunction with our RogaDAQ 384.
 
Specifically, I show the calibration of the measurement chain, which consists of the FFT analysis software, a measurement microphone, a USB data acquisition unit, and a microphone calibrator.
 
Subsequently, an ultrasonic source is captured using the measurement microphone.

High SPL Microphone Calibrator 180 dB

In this presentation, I demonstrate how high-level measurement microphones can be tested to their limits using the CA935.

The CA935 can be used to test all 1/4″, 1/2″, and 1″ microphones.

Industrial customers can send us their microphones for maximum SPL verification for a calibration fee of 280 euros plus shipping costs.

Please contact us to schedule a calibration appointment.

The MP30-Blast 1/2″ measurement microphone is designed for use with explosions or gas deflagrations. For precise measurement of pressure waves below 2 Hz, the optional MKS 222 E infrasound microphone capsule is available.
 
Typical applications include measuring blasts in mines and other acoustic events involving high sound pressure levels. Electrical connection is made via the permanently integrated BNC connector using standard BNC cables.

The MI-MKPL microphone holder is recommended for mounting the microphone. Accessories for 1/2″ measurement microphone capsules—such as windscreens or the MR40 rain protection set for continuous outdoor monitoring—can be used.
 
The measurement microphone can be calibrated using the 4010 sound calibrator (preferred) or other suitable sound pressure calibrators.

MP30-R-Infra Set

Outdoor IEPE Microphone

Weatherproof IEPE Infrasound Microphone

The sound inlet, positioned at a 90° angle to the microphone axis, is ideally suited for monitoring ambient noise starting at 0.5 Hz as well as sound up to 20 kHz.
 
The MP30-R-Infra utilizes the MKS 222 E 1/2″ microphone capsule (Class 1 per IEC 61672, Type WS2F), which is specifically designed for infrasound measurements.
 
It is the optimal choice for long-term outdoor applications—such as infrasound arrays for locating infrasound sources—even in rain or extreme temperatures.
 
For measuring high sound pressure levels up to 150 dB, the MP30-R-Infra-Blast model is available with reduced sensitivity.
 
The measurement microphone can be calibrated using the 4010 or CA111 sound calibrators, or other suitable sound pressure calibrators.
  • Sensitivity 45 mV/Pa
  • IEPE supply 2-20mA BNC
  • Frequency Response: 0.5 Hz – 20 kHz
  • Class 1 WS2F – DIN IEC 61094-4
  • Acoustic noise floor 15 dB(A)
  • Measurement range to SPL Peak (5% Dist.) 135 dB
  • Temperature range -25 to +100 °C
