ADDCO Product Lines We Repair
Our engineers are trained on the full ADDCO product range. Below are the major product families we service.
ADDCO Standard Load Cells
Analog and digital load cells for tension, compression, and shear applications. Common failures include cable jacket degradation, signal conditioning circuit failures, and excitation voltage loss in harsh industrial environments.
ADDCO Weigh Modules & Platforms
Complete weighing systems combining load cells, mounting hardware, and electronics for hopper scales and platform scales. Typical repair issues include load cell imbalance, corner load errors, and junction box moisture ingress.
ADDCO Digital Indicators & Amplifiers
Standalone and integrated digital display and signal conditioning units for load cell output. Common faults include display segment failure, zero drift, calibration loss, and damaged input terminals.
ADDCO Smart Weighing Controllers
Industrial PC-based and standalone controllers for multi-point weighing, batching, and process control. Failures often stem from software corruption, analog input card degradation, or communication port faults.
ADDCO Compression & S-Beam Cells
High-capacity load cells for dead-load measurement and tank/silo weighing. Repair complexity includes bridge resistance imbalance, strain gauge delamination, and solder joint cracking from thermal cycling.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common ADDCO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ADDCO equipment arriving at our workshop.
- ✓ADDCO load cell zero drift and creep — Mechanical stress, temperature fluctuations, and internal strain gauge drift cause the zero reference point to shift over time. Moisture ingress into sealed load cells accelerates this in humid Indian industrial environments.
- ✓ADDCO indicator display segment failure — LCD or LED segment burnout results from excessive current, voltage spikes, or thermal stress. Defective liquid crystal polymers and faulty driver circuits are common in older ADDCO 4300 and 3200 series units.
- ✓ADDCO junction box and connector corrosion — IP67-rated connectors and junction boxes degrade from salt spray, moisture, and chemical exposure typical in Indian chemical plants, food processing, and coastal manufacturing zones. Oxidation corrodes gold-plated contacts and PCB traces.
- ✓ADDCO load cell signal loss and intermittent output — Microfractures in solder joints, fatigue in load cell cables, and internal excitation voltage regulation failures cause intermittent or zero signal. Cable flexing near junction points and vibration-induced damage are typical root causes.
- ✓ADDCO multi-cell summing amplifier calibration loss — Precision resistor drift, capacitor leakage, and reference voltage failures in ADDCO analog summing circuits cause weight reading inaccuracy across hopper or platform scales. Thermal stress and component aging degrade accuracy over years.
- ✓ADDCO controller communication and software failure — SD card corruption, corrupted firmware uploads, faulty Ethernet or RS-485 ports, and damaged analog-to-digital converter boards cause loss of weighing data and network connectivity. Power surges and improper shutdown damage boot sectors.

Frequently Asked Questions — ADDCO Repairs
Do you repair ADDCO equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full ADDCO product range — load cells, weigh modules, digital indicators, summing amplifiers, and smart weighing controllers. We offer PAN India door pickup service from major cities including Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other regions. All repairs are conducted at our ISO-certified facility in Vadodara, Gujarat.
How do you test and calibrate ADDCO load cells after repair?+
Synchronics uses precision dead-weight calibration rigs traceable to national standards (NIST equivalent). We perform zero balance, full-scale calibration, temperature compensation testing, and environmental stress screening for all repaired ADDCO load cells. Calibration certificates with traceability are provided. We test across 0-100 percent load range and verify linearity, hysteresis, and creep within ADDCO original specifications.
What is the typical turnaround time for ADDCO load cell repair in India?+
Standard ADDCO load cell repairs are completed in 5-7 working days from receipt. Complex failures involving strain gauge replacement or potting repairs require 7-10 days. Express turnaround (3-4 days) is available for critical hopper scales and platform weighing systems. Synchronics maintains spare ADDCO load cells and modules for emergency swaps while your original unit is under repair.
Can Synchronics repair ADDCO load cells with broken cables and connectors?+
Yes. Synchronics replaces damaged ADDCO load cell cables with genuine shielded, strain-relieved cable assemblies matching original specifications. Broken or corroded connectors are replaced with IP67-rated industrial connectors, and all terminations are re-soldered per ADDCO wiring diagrams. We re-test insulation resistance to >100 megohms before calibration and shipment.
Do you stock ADDCO replacement parts and modules in India?+
Synchronics maintains an inventory of common ADDCO components including load cell cable assemblies, display modules for 4300 indicators, summing amplifier boards, and strain gauge sets. For complete weigh modules or specialized load cells, we source OEM parts with lead times of 7-14 days. We recommend preventive maintenance contracts to stock critical ADDCO spare parts at your facility.
How do I send my ADDCO 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 ADDCO 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 ADDCO 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 ADDCO 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.
