Measurement Microphones

Accurate. Flexible. Valuable.

  • Class 1 - Certified Precision Microphone
  • Cost-effective Class 2 Microphone
  • Outdoor Measurement Microphone

Accessories Technical Data

The measurement microphones are optimized for a flat, free-field response in the frequency range 5 Hz - 20 kHz. Models for acoustic measurements of up to 155 dB are available.

All microphones are omni-directional and 48V phantom powered. The XL2 Analyzer microphones include an electronic data sheet. The Automated Sensor Detection (ASD) of the XL2 automatically reads this data sheet, and recognizes the microphone model, sensitivity and calibration data. This ensures accurate measurement results.

Measurement Microphones for the XL2 Analyzer

The microphones are 48V phantom powered and include an electronic data sheet. The Automated Sensor Detection (ASD) of the XL2 Analyzer automatically reads this data, i.e. the microphone model and calibration data. This promotes faster setup and ensures accurate measurements.

The microphone bodies contain the preamplifier. They combine high dynamic range and wide frequency range with low noise. These measurement microphones connect via the ASD Cable to the XL2 Audio and Acoustic Analyzer, e.g. for measurements at remote locations or to reduce acoustic reflections. The types M2230, M2211 and M2215 are formed by a combination of preamplifier MA220 and a dedicated microphone capsule. The M2340 is formed by the preamplifier MA230 and the microphone capsule.

Features:

  • Omni-directional, free-field microphone
  • Phantom power 48 VDC
  • Electronic data sheet installed
  • Frequency range 5 Hz - 20 kHz
  • Individual frequency response available as Excel-data
  • Optional calibration certificate

Outdoor Measurement Microphone

Outdoor Measurement Microphone

The Outdoor Measurement Microphones offer a weather-protected measurement solution for the XL2 Sound Level Meter allowing acquisition of environmental noise data in outdoor applications. The corrosion-free polymer housing, wind screen, waterrepellent membrane and bird spike provide excellent protection from rain, wind, dust and perching birds.

The Outdoor Measurement Microphones M2230-WP and M2340-WP fulfill the Class 1 requirements according to IEC 61672 and ANSI S1.4 for vertical sound incidence. For compliance with horizontal sound incidence a spectral correction is employed in the associated XL2 Sound Level Meter. The Outdoor Measurement Microphone M4261-WP fulfills the Class 2 requirements accordingly.

The outdoor microphones consist of a measurement microphone and the applicable weather protection:

  • M2230-WP: M2230 + WP30 Weather Protection
  • M2340-WP: M2340 + WP30 Weather Protection
  • M4261-WP: M4261 + WP61 Weather Protection

Features

  • Class 1 and Class 2 Outdoor Measurement Microphones for vertical and horizontal sound incidence according IEC 61672 and ANSI S1.4 (with XL2)
  • Excellent protection from rain and dust (IP54), wind and perching birds
  • Built from corrosion-free materials
  • Removable top section for easy microphone calibration
  • Standard tripod mount, optional pole mount

Effective outdoor protection

The 90 mm wind screen protects the measurement microphone from rain and dust while reducing wind-induced noise by approximately 15 dB. The seamless design of the water-repellent membrane under the wind screen ensures perfect protection from rain and dust.

System self-test 

The Outdoor Measurement Microphone M2340-WP is system self-test (CIC) enabled. Automated self-tests may be performed by NoiseScout, the unattended noise monitoring solution, in combination with the XL2 Sound Level Meter. This ensures reliable operation and precise measurements.

Robust design / Easy calibration

The upper section of the weather protection is snap-on mounted and can thus be easily removed by hand for manual calibration of the measurement microphone.

Measurement Microphones for Flexus FX100

The M2010 and M2015 are compact, high-performance measurement microphones dedicated to research, design lab, end-of-line testing and service with the Flexus FX100 Audio Analyzer. They are particularly suited for applications with restricted available space. The connection cable to the preamplifier is detachable and a calibration certificate included.

Features:

  • 1/2" Omni-directional, free-field microphone
  • Phantom power 48 VDC
  • Frequency range 20 Hz - 20 kHz
  • Calibration certificate included
  • Detachable Cable
