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.

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
  • M2230, M2211, M2215 are formed by a combination of preamplifier MA220 and a dedicated microphone capsule

Outdoor Measurement Microphone M2230-WP

Outdoor Measurement Microphone
The M2230-WP is a weather-protected outdoor microphone for the XL2 Sound Level Meter. It facilitates acquisition of data in outdoor environmental noise monitoring applications. The corrosion-free polymer housing, wind screen, water-repellent membrane and bird spike provide excellent protection from rain, wind, dust and perching birds. The M2230-WP consists of an M2230 microphone fitted into a WP30 weather protection kit.
 

Features:

  • IEC 61672 Class 1 and ANSI S1.4 Type 1 compliant for vertical and horizontal sound incidence
  • Excellent protection from rain and dust (IP54), wind and perching birds
  • Built from corrosion-free materials
  • Removable top section for easy microphone calibration
  • Standard 3/8” tripod mount
  • Optional sturdy outdoor carrying case available

Class 1 Microphone

The outdoor microphone M2230-WP fulfills IEC 61672 Class 1 as well as the ANSI S1.4 Type 1 requirements for vertical sound incidence. For compliance with horizontal sound incidence a spectral correction is employed in the associated XL2 Sound Level Meter.

Effective outdoor protection

The 90 mm wind screen protects the M2230 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.

Robust design / Easy calibration

The upper section of the weather protection kit is snap-on mounted and can thus be easily removed by hand for convenient and quick 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
