BRUEL & KJAER Equipment We Repair — By Category
BRUEL & KJAER Product Lines We Repair
Our engineers are trained on the full BRUEL & KJAER product range. Below are the major product families we service.
PULSE Platform Analysers
Multi-channel acoustic and vibration analysis systems for structural testing, noise source identification, and modal analysis. Common issues include input channel faults, signal conditioning board failures, and software licensing problems requiring recalibration.
Hand-Held Vibration Meters
Portable vibration measurement devices for ISO 10816 and ISO 20816 compliance monitoring in rotating machinery. Typical faults include accelerometer sensor drift, display malfunction, and battery charging circuit degradation.
Environmental Sound Level Meters
Precision sound measurement instruments for noise mapping, workplace safety audits, and environmental compliance. Common failures involve microphone element aging, preamplifier noise floor rise, and calibration drift over extended operational periods.
Accelerometer Sensors and Transducers
Piezoelectric and IEPE accelerometer sensors for condition monitoring and vibration data acquisition. Repair challenges include connector corrosion, internal piezo element damage, and sensitivity calibration loss due to environmental exposure.
Measurement Software and Drivers
BK Connect and PULSE LabShop software platforms for real-time data acquisition, FFT analysis, and trending. Issues include driver compatibility, USB interface failure, software license corruption, and measurement data export problems.

Common BRUEL & KJAER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BRUEL & KJAER equipment arriving at our workshop.
- ✓PULSE analyser no input signal detection — Signal conditioning cards experience micro-crack solder joints under thermal cycling in Indian manufacturing environments. Front-end amplifier chips also fail due to voltage transient damage from inadequate power conditioning.
- ✓Accelerometer sensitivity drift and noise floor rise — Moisture ingress into accelerometer connector housings combined with high humidity in coastal and monsoon-affected Indian plants causes piezoelectric element leakage. Solder joint degradation in preamplifier stages reduces signal-to-noise ratio.
- ✓Sound level meter display blank or partial segments missing — LCD display driver chips and segment connection failures occur after 5-7 years of continuous operation in factory floors. Preamplifier power supply glitches can also corrupt display circuitry.
- ✓USB data transfer and software communication failure — USB interface chips degrade due to electrostatic discharge in dry industrial environments. Software driver corruption or Windows updates can block legacy BK Connect versions. Faulty front-end circuits can generate noisy data streams that crash acquisition software.
- ✓Inconsistent vibration readings across measurement sessions — Calibration data loss in non-volatile memory, sensor mounting looseness, or changes in transducer sensitivity due to mechanical shock. Bruel & Kjaer instruments require annual recalibration per ISO 16063 standards.
- ✓PULSE software licensing error and module lock-out — Hardware security key (dongle) corruption, Windows registry damage, or network license server misconfiguration prevent software activation. Expired maintenance contracts can also lock measurement modules.

Frequently Asked Questions — BRUEL & KJAER Repairs
Do you repair Bruel & Kjaer equipment anywhere in India?+
Yes. Synchronics repairs the full Bruel & Kjaer product range — PULSE analysers, hand-held vibration meters, sound level meters, and accelerometer sensors. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Nashik, Belgaum, and all other cities. All repairs are performed at our 10,000 sq. ft. facility in Vadodara, Gujarat with turnaround times of 7-14 days.
How often should Bruel & Kjaer vibration analysers be recalibrated?+
ISO 16063-41 standards require annual metrological recalibration of vibration transducers and analysers used in predictive maintenance programmes. Synchronics performs full sensitivity recalibration using certified calibration shakers with traceable reference certificates. We maintain calibration data and alert customers when annual service is due.
Can Synchronics repair Bruel & Kjaer PULSE platform software issues?+
Yes. We repair USB driver failures, re-flash embedded firmware, perform Windows OS compatibility updates, and restore corrupted measurement module licenses. We also provide BK Connect software installation support and troubleshoot data export failures to Excel and analysis platforms.
What is included in Bruel & Kjaer condition monitoring service repair?+
We replace faulty accelerometer elements, repair signal conditioning circuits, recalibrate sensitivity per factory specifications, and provide calibration certificates. Full functional testing includes noise floor measurement, frequency response verification, and trending accuracy validation — critical for ISO 10816 machinery health monitoring compliance.
Do you stock Bruel & Kjaer spare parts and accelerometer sensors?+
Synchronics maintains inventory of common replacement parts including accelerometer cartridges, USB interface modules, LCD displays, and power supply boards. We also source authentic Bruel & Kjaer sensors and connectors through our established supplier network in Germany and Denmark. Lead times are 2-5 days for most components.
How do I send my BRUEL & KJAER unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a BRUEL & KJAER drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on BRUEL & KJAER repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your BRUEL & KJAER unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
