Description

Designed to comply with all relevant international standards and recommendations and is equally well suited for use in national calibration laboratories and commercial calibration centres.
Sound Level Meter Calibration System Type 3630-A complies with all relevant international standards and recommendations and is equally well suited for use in national calibration laboratories and commercial calibration centres.

Type 3630-A is based on the calibration platform Type 3630, a modular multifunctional system, which offers a multitude of different calibration applications, for example, customised applications such as hydrophone phase calibration or microphone high-pressure calibration

The system calibrates Brüel & Kjær as well as other manufacturers’ sound level meters, in accordance with IEC 60651, IEC 60804, IEC 61672 and relevant ANSI standards. It comes with defined procedures and uncertainty calculations for Brüel & Kjær sound level meters and a tool to define others.

Type 3630-A is based on the PULSE analyzer platform capable of analysing FFT, 1/n-octave filters and overall levels. PULSE also generates the test signals to fulfil the requirements of international standards. An integrated digital voltmeter DMM Agilent 34970 and Brüel & Kjær’s Multifunction Acoustic Calibrator Type 4226 guarantee the measurement chain.
