SERCEL Equipment We Repair — By Category
SERCEL Product Lines We Repair
Our engineers are trained on the full SERCEL product range. Below are the major product families we service.
SERCEL Geophones and Velocity Sensors
Single and multi-component geophone units used in seismic surveys. Common issues include coil wire breakage, magnet degradation, connector corrosion, and frequency response drift due to environmental stress or mechanical shock.
SERCEL Accelerometers and Seismic Sensors
High-sensitivity accelerometer assemblies for vibration monitoring and earthquake detection. Failures typically manifest as zero output, intermittent signal dropout, high noise floor, or sensitivity calibration loss from thermal cycling or moisture ingress.
SERCEL Signal Conditioning and Preamplifier Units
Charge amplifiers, voltage regulators, and signal conditioning electronics that amplify and filter sensor outputs. Repair focuses on component-level failures in Op-Amps, capacitor leakage, power supply instability, and impedance matching issues.
SERCEL Data Acquisition and Logger Electronics
Portable and stationary data loggers, digitizers, and acquisition interfaces for seismic field campaigns. Common faults include SD card interface failures, USB port damage, battery charging circuit failure, and memory corruption from abrupt shutdown.
SERCEL Cable Assemblies and Connectors
Specialized multi-pin connectors, BNC adapters, and shielded field cables designed for low-noise geophysical applications. Degradation occurs from moisture contamination, salt-spray corrosion in coastal surveys, mechanical fatigue from repeated deployment cycles, and pin oxidation.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common SERCEL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SERCEL equipment arriving at our workshop.
- ✓Geophone coil open circuit or intermittent connection — Extended field deployment, vibration-induced fatigue, or moisture corrosion inside the geophone housing. The moving coil's fine wire may fracture at connection points, especially in high-vibration environments like mining or blasting surveys.
- ✓Accelerometer zero output or constant DC offset — SERCEL accelerometers often fail due to charge amplifier saturation from DC coupling errors, capacitor leakage in the charge feedback network, or internal piezo element fracture from mechanical shock or thermal stress during field transport.
- ✓Intermittent signal dropout or noise floor elevation — SERCEL field cables exposed to salt spray, UV exposure, or mechanical abrasion develop insulation breakdown and pin corrosion. Water ingress into connectors creates capacitive leakage paths, degrading signal-to-noise ratio in low-amplitude seismic recordings.
- ✓Data logger SD card unrecognized or file corruption — SERCEL loggers in remote field locations may experience abrupt power loss during file write operations, SD card contact oxidation from heat cycling, or firmware bugs in older logger models when handling large multi-day survey datasets.
- ✓Preamplifier gain mismatch or frequency response flat spot — SERCEL preamplifier Op-Amp drift, resistor tolerance creep, or capacitor aging causes gain variation between channels and narrow-band frequency notches. This is critical in multi-channel seismic arrays where gain matching directly impacts data quality for velocity analysis.
- ✓Connector pin oxidation or intermittent contact resistance — SERCEL multi-pin connectors in coastal or humid environments experience accelerated oxidation on gold or silver plating. Repeated mating cycles, salt-fog exposure, and inadequate grease sealing create micro-arcing and contact resistance spikes during data transmission.

Frequently Asked Questions — SERCEL Repairs
Do you repair SERCEL equipment anywhere in India?+
Yes. Synchronics repairs the complete SERCEL seismic sensor and acquisition product range—geophones, accelerometers, preamplifiers, signal conditioning modules, and data loggers. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other metros and industrial towns. All repairs are performed at our main facility in Vadodara, Gujarat, with turnaround times of 7-14 days for standard repairs.
How do you handle SERCEL geophone calibration and frequency response verification?+
After repair, every SERCEL geophone is tested on our calibrated shake table with known reference accelerations across the 5Hz to 100Hz range. We verify natural frequency, damping ratio, sensitivity (mV/g or mV/cm/s), and harmonic distortion. A full calibration certificate traceable to ISO standards is provided with each geophone, essential for oil majors and government survey agencies in India.
What if my SERCEL sensor has been in storage for years—can it be brought back to service?+
Yes. Synchronics performs 'pre-deployment refurbishment' on dormant SERCEL equipment. We inspect connectors for corrosion, test coil continuity, verify capacitor ESR values, recalibrate sensitivity if needed, and conduct burn-in testing under simulated field conditions. This is common for survey companies redeploying legacy SERCEL arrays after 3-5 year gaps.
Do you offer on-site repair support for large SERCEL seismic survey projects?+
Yes. For major oil and gas exploration campaigns, mining surveys, or earthquake network deployments across India, Synchronics provides on-site technician support. We can troubleshoot field issues, swap faulty channels, perform bench checks on-location, and arrange emergency replacement units. Contact our project engineering team for custom support plans.
What is the typical cost and lead time for SERCEL multi-channel accelerometer array repair?+
Lead time depends on fault scope: intermittent connector issues (3-5 days), capacitor/amplifier repairs (5-7 days), sensor replacement or coil rewinding (10-14 days). Costs range from INR 8,000 per channel (connector cleaning) to INR 35,000+ for full sensor replacement or calibration. We provide upfront quotation based on diagnostics at no charge.
How do I send my SERCEL 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 SERCEL 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 SERCEL 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 SERCEL 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.
