USON Equipment We Repair — By Category
USON Product Lines We Repair
Our engineers are trained on the full USON product range. Below are the major product families we service.
USON Leak Detection Systems
Automated non-destructive leak detection for automotive components, hydraulic assemblies, and pressure vessels. Common issues include pressure transducer drift, calibration loss, and sensor signal degradation after extended operation in humid factory environments.
USON Pressure Decay Analysers
High-precision instruments for measuring micro-leaks in sealed systems and assemblies. Frequent repairs involve signal conditioning electronics, digital display failures, and pneumatic valve stiction in Indian dust-heavy industrial settings.
USON Fluid Analysis & Contamination Monitoring
Real-time particle counting and fluid condition monitoring for hydraulic and lubrication systems. Repair challenges include optical sensor contamination, flow cell blockage, and data logger memory failures in high-temperature operations.
USON Control & Data Acquisition Modules
Integrated electronics for test sequencing, data logging, and remote reporting of USON instruments. Common faults include relay degradation, RS-232/RS-485 communication failures, and power supply instability under fluctuating Indian grid conditions.
USON Transducers & Sensors
Precision pressure, temperature, and differential transducers designed for USON test benches. Failures typically stem from condensation ingress, connector corrosion, and signal drift in repetitive automotive supplier testing cycles.
Why Choose Synchronics for USON Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on USON equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common USON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in USON equipment arriving at our workshop.
- ✓Pressure transducer zero drift and calibration loss — Extended exposure to humidity and thermal cycling in Indian manufacturing plants causes the USON transducer diaphragm to develop micro-leaks and drift. Calibration offset accumulates after 12-18 months of continuous operation without recalibration.
- ✓Display panel goes blank or shows garbled characters — The USON 2000/3000 series liquid crystal display (LCD) degrades due to heat stress near furnaces and paint shops. Solder joint failure on the display connector board is common in vibration-prone automotive assembly lines.
- ✓No communication — USB or RS-485 port not recognised — The USON DataLog Module's communication chipset (typically a Silicon Labs USB-to-serial converter) fails due to electrostatic discharge (ESD) during sensor connections in dry Indian climate conditions. Connector pins corrode from salt-laden air in coastal manufacturing zones.
- ✓Intermittent pressure readings and sensor dropouts during test cycles — USON instrumentation relies on stable 24 VDC power supply, which fluctuates unpredictably in many Indian industrial zones due to unstable grid voltage and inadequate UPS buffering. Capacitor drying on the power conditioning board is a secondary cause.
- ✓Flow cell blockage in fluid analysis module — no particle count output — USON Fluid Monitor and Particle Counter modules accumulate contaminants (metal fines, dust, water droplets) in the optical flow cell when used in unfiltered hydraulic systems common to Indian textile, sugar, and steel plants. The sensor windows become opaque over 6-12 months.
- ✓Data not logging or SD card corruption on control module — The USON Control Unit CU-1 uses microSD cards which fail due to power loss during write cycles (common in Indian plants with unstable electricity). The data logger firmware also becomes unstable after multiple thermal shock cycles in non-air-conditioned facilities.

Frequently Asked Questions — USON Repairs
Do you repair USON equipment anywhere in India?+
Yes. Synchronics repairs the full USON product range — leak detection systems, pressure decay analysers, fluid analysis modules, and data acquisition electronics. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Surat, and all other major cities. Your equipment is serviced at our fully equipped facility in Vadodara, Gujarat, with turnaround typically 5-7 working days.
My USON leak detector shows zero-drift after years of use. Can it be recalibrated?+
Absolutely. Zero-drift in USON transducers is very common and fully repairable. Synchronics performs a complete transducer replacement with full zero and span calibration against ISO-certified pressure standards. The calibration certificate we issue is valid for 12 months and accepted by automotive OEMs and tier-1 suppliers across India.
What should I do if my USON fluid analysis module stops counting particles?+
The optical sensor window has likely become contaminated or blocked by particulates from your hydraulic system. Do not attempt to clean the flow cell yourself, as improper handling damages the precision optics. Ship the module to Synchronics. Our engineers will perform ultrasonic cleaning, sensor recalibration using ISO test fluids, and full functional testing before return. Most repairs complete within 5-7 days.
Why does my USON control module lose communication with my computer during data logging?+
This is typically caused by power supply instability (very common in Indian industrial zones) or corrupted microSD card firmware. Synchronics upgrades your power conditioning stage, replaces the storage card with an industrial-grade device, and updates your control firmware. We also recommend a regulated industrial UPS to protect against voltage fluctuations. This comprehensive solution prevents future dropouts.
How do I know if my USON transducer needs replacement or just recalibration?+
If your transducer drifts more than 2% of full scale despite recalibration, or if it shows erratic spikes, the internal diaphragm or electronics are likely degraded. Synchronics provides free diagnostic testing — ship us the transducer and we will perform a full test report. If replacement is needed, we offer original USON transducers and cross-compatible alternatives at competitive rates, with same-day calibration upon receipt.
How do I send my USON 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 USON 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 USON 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 USON 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.
