Lion Precision Equipment We Repair — By Category
Lion Precision Product Lines We Repair
Our engineers are trained on the full Lion Precision product range. Below are the major product families we service.
Eddy Current Displacement Sensors
Non-contact AC and DC displacement sensors for precision measurement in metal environments. Common issues include probe tip wear, cable shielding degradation, and oscillator drift affecting measurement linearity and repeatability.
Proximity Probe Systems
High-temperature proximity probes for rotating machinery condition monitoring and blade tip clearance measurement. Frequent faults include connector corrosion, signal amplifier failure, and zero/span drift in harsh industrial environments.
Signal Conditioners and Controllers
Standalone and modular signal conditioning units converting sensor output to 4-20 mA and digital signals. Repair focuses on amplifier board failure, filtering circuit degradation, and calibration memory loss due to power surges.
Gauss Meter and Magnetic Field Sensors
Portable and fixed gauss meter systems for measuring magnetic field strength in industrial testing. Common faults include sensor non-linearity, battery drainage, and firmware calibration errors.

Common Lion Precision Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in Lion Precision equipment arriving at our workshop.
- ✓Eddy current probe zero drift and span loss — Lion Precision eddy current probes experience zero drift when tip wear occurs or when oscillator frequency drifts due to component aging. Environmental temperature swings and vibration loosen internal calibration tuning in signal conditioners.
- ✓4-20 mA output signal intermittent or noisy — Cable shielding breakdown and connector oxidation in harsh plant environments create low-impedance paths. Internal amplifier coupling capacitors in signal conditioners degrade, introducing high-frequency noise and signal dropout.
- ✓Proximity probe high-temperature failure and connector degradation — High-temperature proximity probes used in furnace monitoring experience insulation breakdown in connectors rated below actual operating temperature. Thermal cycling causes internal solder joint cracking and lead frame corrosion.
- ✓Signal conditioner no display or digital communication loss — Power supply regulator failure in Lion Precision controllers causes display blackout. Microcontroller firmware corruption and EEPROM calibration data loss occur due to sudden power surges or improper shutdown sequences.
- ✓Gauss meter reading non-linearity and range errors — Magnetic sensor Hall-effect element degradation and amplifier DC offset drift cause non-linear response across measurement range. Temperature coefficient mismatch accelerates in equipment not recalibrated annually per manufacturer guidance.
- ✓Probe cable intermittent open circuit and shielding failure — Flexing and vibration fatigue copper strands in unshielded sensor cables. Poor strain relief at connectors allows moisture ingress into probe housing, causing insulation tracking and intermittent open circuits.

Frequently Asked Questions — Lion Precision Repairs
Do you repair Lion Precision equipment anywhere in India?+
Yes. Synchronics repairs the full Lion Precision product range — eddy current sensors, proximity probes, gauss meters, and signal conditioning systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, and all other major cities. All repairs completed in our certified facility in Vadodara, Gujarat with 2-3 week turnaround for most units.
Can you recalibrate Lion Precision eddy current probes to original specifications?+
Yes, absolutely. Synchronics performs complete re-calibration of Lion Precision eddy current displacement sensors using precision test fixtures traceable to international standards. We restore zero offset, span linearity, and temperature compensation coefficients. Each unit receives calibration certificate valid for 12 months, and we maintain records for traceability and compliance audits.
What is the typical repair turnaround for Lion Precision proximity probes?+
For high-temperature proximity probes, turnaround is typically 10-14 working days from receipt. This includes diagnostic testing, component replacement (connectors, solder joints, seals), thermal chamber testing at operating temperature, and final functional validation. Express expedited service available for critical production support — contact our team for availability.
Our Lion Precision signal conditioner shows zero drift after power surges — is it repairable?+
Yes. Power surge damage to Lion Precision SC-3200 and SC-3300 signal conditioners is common and usually repairable. Synchronics replaces surge-damaged voltage regulators, re-programs microcontroller firmware, restores calibration data, and applies enhanced surge protection. We advise installing UPS and surge suppressors to prevent recurrence.
Do you stock Lion Precision spare parts and probe tips?+
We maintain inventory of common replacement parts including eddy current probe tips, connectors, and signal conditioner boards. For specialized components, we source directly from Lion Precision or authorized distributors in USA. We recommend keeping spare proximity probes and cables on-site for critical machinery — contact us to establish predictive replacement schedules.
How do I send my Lion Precision 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 Lion Precision 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 Lion Precision 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 Lion Precision 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.
