Expert repair of Hilger optical and laser measurement systems across Indian manufacturing.
HILGER Product Lines We Repair
Our engineers are trained on the full HILGER product range. Below are the major product families we service.
LAS-16 / LAS-20 Laser Triangulation Sensors
Compact laser displacement and thickness measurement sensors used in metal stamping, sheet feeding, and conveyor gap detection. Common failures include laser module degradation, photodiode signal loss, and connector corrosion in humid shop-floor environments.
Optical Gauging Systems (OGS) / Vision Gauge Controllers
Industrial vision-based measurement and part profile scanning systems for inline quality control. Repair challenges involve CCD/CMOS sensor contamination, image processing unit failures, and communication protocol errors in networked gauging setups.
Confocal Displacement Sensors / DFS-Series
High-precision confocal sensors for distance and thickness measurement in automotive and pharma manufacturing. Failures stem from optical element fouling, beam path misalignment, and signal amplifier faults in electromagnetic-noisy environments.
Eddy-Current and Capacitive Proximity Systems
Non-contact sensors for metal and material detection integrated with Hilger measurement platforms. Common issues include sensor drift, coil winding breakdown, and oscillator frequency instability under high-temperature production conditions.
Measurement Control Units (MCU) / Process Controllers
Standalone and PLC-integrated controllers for multi-sensor measurement and SPC (Statistical Process Control) integration. Failures involve power supply failures, relay board degradation, analog I/O card faults, and firmware corruption.

Common HILGER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HILGER equipment arriving at our workshop.
- ✓Laser module output loss or flickering — Hilger laser diodes degrade after 10,000+ operating hours; thermal stress from ambient temperature swings in uncontrolled shop floors accelerates decay. Mirrors and optics become contaminated by airborne metal particles in stamping and machining operations.
- ✓Signal dropout or intermittent measurement readings — Electrical connectors corrode in humid, coolant-saturated environments; solder joints crack on signal conditioning PCBs from vibration; photodiode or CCD sensors lose responsiveness due to age or ESD damage.
- ✓Measurement offset or calibration drift over time — Optical components shift position due to thermal cycling, vibration, and mechanical wear; lens contamination reduces contrast and sensor accuracy; internal reference standards drift in measurement controllers after years of service.
- ✓Communication errors or protocol timeouts (Profibus, CANopen, Ethernet) — Hilger MCUs and network modules suffer from EMI ingress in heavy industrial settings; firmware corruption from power surges; RS-485 termination resistors fail; Ethernet port circuitry degrades.
- ✓Power supply failures or rail voltage instability — 24VDC supply modules and linear regulators fail from thermal stress in high-ambient-temperature plants; filter capacitors dry out; Over-voltage protection circuits trip from power surges.
- ✓Optical sensor contamination or lens coating degradation — Metal shavings, coolant mist, and dust accumulate on Hilger sensor windows in machine shops; anti-reflection coatings scratch or delaminate; protective windows cloud from chemical exposure.

Frequently Asked Questions — HILGER Repairs
Do you repair Hilger equipment anywhere in India?+
Yes. Synchronics is the authorized repair facility for Hilger optical and laser measurement systems across India. We offer same-day or next-day PAN India pickup via our logistics partners from Mumbai, Pune, Ahmedabad, Delhi, Hyderabad, Chennai, Kolkata, and all other industrial cities. Equipment is transported to our Vadodara, Gujarat facility where our team performs diagnosis, repair, and full-system calibration. Typical turnaround is 7-10 business days including re-certification.
Can you recalibrate Hilger measurement sensors to our production tolerance?+
Absolutely. Synchronics maintains ISO 9001 calibration standards and use certified reference standards for recalibrating Hilger optical and laser sensors. We verify measurement accuracy to ±0.01-0.05mm depending on your sensor type. For automotive and pharma customers, we provide NABL-traceable calibration certificates. If your production tolerance requires special reference blocks or gauge pins, we source them or work with your in-house standards lab.
What is the typical lifespan of a Hilger laser diode or optical sensor?+
Hilger laser diodes typically deliver 10,000-15,000 operating hours before power output degrades below 80% of specification. Optical sensors (CCD/CMOS) last 15,000+ hours with proper environmental sealing. In Indian machine shops running 16+ hours daily, expect 2-3 year service life before recalibration or replacement is needed. Synchronics stocks Hilger OEM laser modules and sensor heads to minimize downtime — contact us for spare parts pricing.
How do I know if my Hilger measurement system has drifted out of spec?+
Monitor your Hilger controller's output trend over weeks. If readings drift more than ±0.5-2% of full scale, or if your SPC (Statistical Process Control) data shows increasing standard deviation, recalibration is due. Synchronics recommends annual calibration verification for critical automotive/pharma applications, and quarterly for high-volume stamping/machining lines. We offer on-site diagnostics using portable reference standards — call us for a no-cost assessment.
Do you support legacy Hilger optical gauge controllers from 2005-2015?+
Yes. Synchronics repairs vintage Hilger MCU, OGS, and custom vision gauge systems from the 2000s onward. We hold archived firmware files, spare PCBs, and connector kits for older models. If a PCB is obsolete, we perform component-level board repair or source compatible replacement electronics. Indian automotive tier-1 suppliers often maintain decades-old tooling with legacy Hilger sensors — we keep them running cost-effectively rather than full replacement.
How do I send my HILGER 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 HILGER 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 HILGER 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 HILGER 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.
