LDIC Equipment We Repair — By Category
LDIC Product Lines We Repair
Our engineers are trained on the full LDIC product range. Below are the major product families we service.
LDIC Compression Load Cells
Stainless steel compression load cells rated 5 tonnes to 500 tonnes. Common failures include diaphragm rupture from overstress, signal drift from moisture ingress into the strain gauge bridge, and connector corrosion in humid chemical plant environments. Synchronics restores full measurement accuracy.
LDIC Tension Load Cells
Welded stainless steel tension cells for suspended weighing in conveyors and hoppers. Typical issues include cable damage, cold solder joints in the strain gauge network, and creep drift in aging cells. We perform full recalibration to original specifications.
LDIC Weight Transmitters and Signal Conditioners
4-20mA and 0-10V transmitters that convert load cell signals into plant control system inputs. Failures stem from power supply burnout, op-amp failure, and loose terminal connections from vibration. Synchronics rebuilds the full electronics and recalibrates output linearity.
LDIC Shear Beam Load Cells
High-accuracy shear beam cells for platform scales, floor scales, and weighbridges common in Indian steel and grain industries. Failure modes include seal degradation allowing water entry, strain gauge wire breakage, and offset drift from thermal shock. Full recalibration included in repair.
LDIC Bending Beam Load Cells
IP67-rated bending beam cells for low-capacity dosing and batching applications in pharmaceutical and food processing. Common faults include connector pin corrosion, signal noise from EMI, and nonlinearity from aging strain gauges. Synchronics performs complete analog frontend restoration.
LDIC S-Beam Load Cells
Miniature S-beam cells for hanging scales and tension measurement in textile looms and paper mills. Failures include solder joint cold-cracking, connector loosening from thermal cycling, and span/zero drift from load hysteresis. Complete bridge rebalancing performed in-house.

Common LDIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in LDIC equipment arriving at our workshop.
- ✓Load cell output signal drift and nonlinearity — Aging strain gauge bridge resistance, moisture penetration into sealed strain gauge cavity, or solder joint degradation from thermal cycling in foundry and kiln environments. LDIC cells in high-temperature zones show accelerated creep over 5-7 years.
- ✓Connector pin corrosion and intermittent signal loss — Moisture and salt air ingress through corroded M12 or 4-pin connectors. LDIC load cells in coastal chemical refineries and sugar plants suffer aggressive corrosion, causing open circuits and signal dropouts.
- ✓Diaphragm rupture and load cell leakage — Overstress from sudden load spikes, metal fatigue at weld bead radius in compression cells, or defective sealing in cells exposed to chemical vapor. Common in weighbridge overload scenarios and batch processing upsets.
- ✓Weight transmitter 4-20mA output locked at 0 or 20mA — Op-amp failure, blown precision resistor network, power supply rail collapse, or A/D converter latch-up from ESD or transient overvoltage. LDIC transmitters used with long unshielded cable runs in steel mills are vulnerable to EMI upset.
- ✓Strain gauge resistance imbalance and bridge null offset — Differential thermal drift across the strain gauge network from uneven heat distribution, moisture-induced resistance variation, or manufacturing tolerance stack-up in aging LDIC cells. Older models show creep from thermal hysteresis.
- ✓Capacitive coupling noise and instability in analog signal path — Loose shielded cable, poor ground continuity between load cell and signal conditioner, or inadequate filtering in LDIC transmitter input stage. Common when long cable runs (>100 m) are used in noisy factory floors with high-power drive systems nearby.

Frequently Asked Questions — LDIC Repairs
Do you repair LDIC equipment anywhere in India?+
Yes. Synchronics repairs the complete LDIC product range including load cells (compression, tension, shear beam, bending beam), weight transmitters, and signal conditioning units. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, Bangalore, and all other industrial cities. All repairs are performed in our ISO 9001 facility in Vadodara, Gujarat. Expected turnaround is 7-15 days for routine recalibration and fault repair.
Can Synchronics recalibrate LDIC load cells to original specifications?+
Yes. Synchronics performs complete NIST-traceable recalibration of LDIC load cells from 1 kg to 500 tonnes capacity. We use precision weights, decade boxes, and digital multimeters certified to ±0.05% accuracy. Load cells are tested at zero, 25%, 50%, 75%, and 100% of rated capacity. A detailed recalibration certificate with before/after readings is issued with every repair.
What is the typical cost and timeline for LDIC load cell repair in India?+
Repair cost depends on fault severity: connector replacement costs Rs 2,500-5,000; strain gauge bridge rebalancing costs Rs 5,000-10,000; transmitter electronics repair costs Rs 8,000-15,000. Recalibration adds Rs 3,000-5,000. Most repairs are completed in 7-10 working days. Synchronics provides free quotation after photo and specification review.
Are LDIC spare components and strain gauge units available?+
Yes. Synchronics stocks original LDIC connector assemblies, strain gauge elements, signal cable, and PCB components for weight transmitters. If original parts are unavailable, we source equivalent-grade industrial electronics from authorized suppliers. For older LDIC models (pre-2000), we perform component-level repair and re-manufacturing of custom strain gauge bridges.
How do I know if my LDIC load cell needs repair versus replacement?+
Common warning signs are: signal drift >2% per hour, output noise >0.5% of span, connector corrosion, or visible diaphragm cracks. Synchronics performs free diagnostic testing: we measure strain gauge resistance balance, test the hermetic seal, and verify signal linearity across the load range. If repair cost exceeds 40% of new cell cost and the cell is >8 years old, replacement is recommended. Otherwise, repair restores full functionality.
How do I send my LDIC 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 LDIC 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 LDIC 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 LDIC 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.
