HYDAC ELECTRONIC Equipment We Repair — By Category
HYDAC ELECTRONIC Product Lines We Repair
Our engineers are trained on the full HYDAC ELECTRONIC product range. Below are the major product families we service.
HYDAC Proportional and Directional Solenoid Drivers
HYDAC's NG6 and NG10 proportional valve driver modules control flow and pressure in closed-loop hydraulic systems. Common failures include coil burnout from voltage spikes, spool stiction from contaminated oil, and solenoid demagnetization. Synchronics performs complete coil replacement, spool cleaning, and magnetic calibration.
HYDAC Electronic Load-Sensing and Pressure Controllers
Load-sensing electronics regulate pump displacement and maintain constant pressure differential in variable displacement systems. Failures stem from sensor signal loss, amplifier circuit degradation, and solenoid response time drift. Synchronics recalibrates sensors, replaces failing op-amp circuits, and restores pressure response accuracy to original specifications.
HYDAC Pressure and Temperature Transducers with Electronics
HYDAC transducers integrate strain gauge bridges with 4-20mA or 0-10V output electronics in harsh hydraulic environments. Failures include signal drift from bridge imbalance, output amplifier failure, and connector corrosion causing intermittent readings. Synchronics performs bridge rebalancing, amplifier section repair, and environmental sealing restoration.
HYDAC Fluid Condition Monitoring and Contamination Sensors
HYDAC condition monitoring electronics detect particle contamination, water ingress, and fluid degradation in real-time. Electronic failures include particle counter circuit malfunction, water-in-oil sensor signal loss, and data communication errors. Synchronics restores sensor calibration, repairs counter electronics, and verifies CANopen/analog output integrity.
HYDAC Proportional Pressure and Flow Control Valves
HYDAC proportional valves integrate solenoid drivers with integrated electronics for precise pressure and flow management. Common failures include proportional coil open circuits, internal spool jams from varnish buildup, and feedback transducer malfunction. Synchronics performs complete coil rewinding, spool rehabilitation, and transducer replacement with full recalibration.

Common HYDAC ELECTRONIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HYDAC ELECTRONIC equipment arriving at our workshop.
- ✓Proportional solenoid coil burnout and open winding — HYDAC proportional coils fail due to transient voltage spikes during valve switching, contaminated hydraulic fluid creating localized heating, or manufacturing defects in coil insulation. Extended operation without proper hydraulic filtration accelerates coil degradation.
- ✓Pressure transducer output signal drift and noise — HYDAC transducers suffer bridge imbalance from thermal cycling, oil contamination on sensor diaphragm surface, or operational amplifier aging in high-temperature hydraulic chambers. Intermittent signal loss often indicates connector corrosion or internal PCB track fracture.
- ✓Load-sensing electronics unable to maintain pressure differential — HYDAC load-sensing amplifier circuits degrade from capacitor aging, feedback signal transducers develop intermittent open circuits, or proportional solenoid response becomes sluggish. System cannot trim pump displacement, resulting in excessive energy waste and heat generation.
- ✓Fluid contamination sensor false alarms and communication loss — HYDAC contamination monitoring sensors generate spurious particle count signals from optical window fouling, water-in-oil sensor electrodes develop electrolytic corrosion, or CANopen/analog communication circuits suffer intermittent failures due to connector degradation in wet plant environments.
- ✓Solenoid response time degradation and hysteresis drift — HYDAC on-off and proportional solenoids lose magnetic strength from thermal cycling, accumulation of iron oxide debris on armature surfaces, or mechanical wear in spool bearing surfaces. Response time becomes sluggish, compromising system stability and control accuracy.
- ✓Connector corrosion causing intermittent electrical contact failure — HYDAC equipment operates in humid Indian manufacturing plants where salt spray and moisture ingress corrode brass connector pins and gold plating. Intermittent signal loss occurs during temperature cycling when corrosion layers expand and contract unpredictably.

Frequently Asked Questions — HYDAC ELECTRONIC Repairs
Do you repair HYDAC ELECTRONIC equipment anywhere in India?+
Yes. Synchronics repairs the complete HYDAC ELECTRONIC portfolio — proportional drivers, load-sensing controllers, pressure and temperature transducers, and contamination monitoring electronics. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Nashik, and all major industrial cities. All repairs are performed in our Vadodara, Gujarat facility with full traceability and calibration certification.
What is your typical turnaround time for HYDAC proportional driver repairs?+
HYDAC proportional driver repairs typically require 5-7 working days including coil replacement, spool rehabilitation, transducer testing, and bench flow validation. Emergency turnaround is available for critical plant outages — we maintain stock of HYDAC-spec replacement coils and electronic components. Synchronics can provide temporary loaner units during extended repairs if required by customer production schedules.
Can you recalibrate HYDAC transducers to customer-specific pressure ranges?+
Yes. Synchronics performs full custom recalibration of HYDAC pressure and temperature transducers using NIST-traceable pressure calibration equipment. We can reprogram 4-20mA or 0-10V output ranges to match customer's specific hydraulic system pressures (e.g., 350 bar, 420 bar). Each transducer receives certification documentation with actual calibration curve data — essential for compliance with Indian automotive and aerospace supply standards.
How do you diagnose HYDAC load-sensing amplifier circuit failures?+
Synchronics uses precision signal analysis equipment to measure amplifier gain, frequency response, and feedback loop stability. We perform capacitor ESR testing to identify aging electrolytic failures, test operational amplifier voltage rails under load, and measure proportional solenoid response time using controlled ramp signals. Complete diagnostics typically identify root cause — capacitor degradation, transducer failure, or solenoid response time drift — guiding cost-effective repair versus replacement decisions.
What warranty do you provide on repaired HYDAC ELECTRONIC equipment?+
Synchronics provides 12-month comprehensive warranty on all HYDAC ELECTRONIC repairs, covering parts, labour, and return shipping across India. Critical electronic components (amplifiers, transducers) carry 24-month coverage if customer maintains recommended hydraulic filtration (ISO 4406 16/14/11 or better). Extended warranty options are available for mission-critical systems — consult our service engineers for customised coverage.
How do I send my HYDAC ELECTRONIC 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 HYDAC ELECTRONIC 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 HYDAC ELECTRONIC 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 HYDAC ELECTRONIC 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.
