Brand: Brüel & Kjær

Description

Overview

The Brüel & Kjær 2250-D-D00 (also written Bruel & Kjaer 2250-D-D00) is a configuration of the Type 2250 hand-held analyzer, the fourth-generation B&K platform for sound and vibration measurement. Type 2250 is a Class 1 sound level meter that can host additional applications such as 1/1- and 1/3-octave frequency analysis, logging (profiling) and signal recording, which makes it suitable for workplace, environmental and product noise assessment from one instrument.

The “-D-D00” suffix is not decoded in the published B&K product data, so the exact software licences and accessory bundle behind this order code are confirmed with the customer before quotation. The specifications below are those published for the Type 2250 platform fitted with its standard microphone and preamplifier.

Brüel & Kjær 2250-D-D00 Ordering Code and Options

Brüel & Kjær sold the Type 2250 as lettered software packages, written 2250-x-Dxx. The letter after the type number fixes which measurement software is licensed on the instrument. Package A carries only Sound Level Meter Software BZ-7222. Package B adds Frequency Analysis BZ-7223, package C adds Logging BZ-7224, and package E adds Enhanced Logging BZ-7225 and Signal Recording BZ-7226.

The 2250-D package, which this part number belongs to, contains three modules as standard: BZ-7222 Sound Level Meter, BZ-7223 Frequency Analysis and BZ-7224 Logging. The last group, Dxx, is a bundle code; the product data does not list what D00 stands for, so the exact accessory bundle should be checked against the delivery note or the licence screen of the instrument.

According to the same document, a Type 2250 is supplied with a Type 4189 (or Type 4190) microphone, preamplifier ZC-0032, 90 mm windscreen, tripod extension, travel bag, protective cover, earphones, battery pack QB-0061, mains supply and a USB cable.

Brüel & Kjær 2250 Selection Notes

Further licences can be added later to the same hardware: BZ-7225 Enhanced Logging, BZ-7226 Signal Recording, BZ-7227 Reverberation Time, BZ-7228 Building Acoustics, BZ-7230 FFT and BZ-7231 Tone Assessment. Field calibration is done with Sound Calibrator Type 4231. Buyers should note that the manufacturer is moving the 2250 series to the B&K 2245 and HBK 2255 families, so new projects may prefer the successor while the 2250 remains relevant for fleet matching and replacement.

About brand

Brüel & Kjær is the Danish name behind two product lines found in industry: precision sound and acoustic instruments, such as the Type 2250 analyser and its measurement microphones, and machine protection and condition monitoring systems from Brüel & Kjær Vibro, such as VIBROCONTROL and VC-6000. Brüel & Kjær was founded in Denmark in 1942. Brüel & Kjær Vibro was formed in 2000 when it merged with the vibration business of Germany's Schenck, and it has been part of Japan's NSK since 2021.

Seven Star LLC is an independent supplier in Muscat. We list Brüel & Kjær vibration sensors, monitors, rack modules and sound instruments, including obsolete modules that are still running in plants in Oman and the GCC, and supply them by exact part number.

Legacy modules	Type 3013 tacho monitor, PS-610 (replaced by PS-615)	Spares for older installed systems
Sound and acoustics	2250-L, 2250-D, Type 2240, 4190 microphone, 4157 ear simulator	Noise surveys, occupational noise and acoustic testing
Cables	AC 0034, AO-0087, AO-0714, AO 0193	Sensor, extension and microphone cables

An eddy-current measuring chain has three parts that must match: the probe, the extension cable and the oscillator (driver). The total electrical length is calibrated as one system, so a probe from one length or model cannot simply be mixed with an oscillator for another. On B&K Vibro part numbers, the digits after the model (for example IN-083/3/070/50/0/206) set the thread, the probe length, the cable length and options, so the full code is needed to supply the right part.

Where Brüel & Kjær products are used

In Oman and the GCC, B&K Vibro sensors and monitors protect gas turbines, steam turbines, compressors, large pumps and fans in oil and gas, power and desalination plants. The sound instruments are used for occupational noise surveys and equipment noise testing.

Ordering Brüel & Kjær parts: what we need

Send the complete part number from the label (including all suffixes after the slash), a photo of the label, and for sensors the probe length, cable length and thread. For rack modules, add the rack type and firmware version if known. For obsolete parts, send the old part number so we can check the replacement.
