LEONHARDT Equipment We Repair — By Category
LEONHARDT Product Lines We Repair
Our engineers are trained on the full LEONHARDT product range. Below are the major product families we service.
Leonhardt Process Controllers
Compact modular controllers for temperature, pressure, and flow process regulation in pharmaceutical and chemical manufacturing. Common issues include sensor interface failures, relay card degradation, and calibration drift requiring full recalibration.
Leonhardt Measurement Instrumentation
Precision analog and digital transducers for pressure, temperature, and level monitoring in processing plants. Typical faults involve amplifier circuit failure, signal conditioning errors, and connector corrosion in humid industrial environments.
Leonhardt Automation Interfaces
Signal conditioning and I/O modules bridging process instruments to PLC and SCADA systems. Common failures include opto-isolator burnout, analog-to-digital conversion errors, and communication protocol mismatches.
Leonhardt Calibration and Test Systems
Portable and bench-top calibrators for field validation of process sensors and transmitters. Repair needs typically involve reference cell degradation, display module failure, and software memory corruption.
Leonhardt Control Panels and Assemblies
Custom-built control enclosures integrating Leonhardt modules with relays, contactors, and power supplies for manufacturing lines. Faults often stem from thermal management issues, connector fatigue, and EMI-induced logic errors.
Leonhardt Legacy Analog Systems
Older generation analog control boards and instrumentation still operating in mature Indian chemical and pharmaceutical plants. Repair challenges include obsolete component sourcing, electrolytic capacitor failure, and potentiometer wear.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common LEONHARDT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in LEONHARDT equipment arriving at our workshop.
- ✓Leonhardt controller calibration offset and measurement drift — Extended operation without calibration verification causes sensor output drift. Temperature cycling in industrial environments degrades internal reference cells in Leonhardt analog modules, leading to gradually increasing measurement error and setpoint inaccuracy.
- ✓Leonhardt relay card contacts pitted and sticking — Excessive switching cycles, inductive load transients, and inadequate arc suppression degrade contact surfaces on Leonhardt relay modules. Arcing during switch-off creates micro-welding and material erosion, preventing reliable relay operation.
- ✓Leonhardt analog I/O module no-signal or false-signal condition — Connector corrosion from humidity and chemical vapors causes intermittent connections on Leonhardt analog interface modules. Cold solder joints on PCB traces and degraded header pins fail under vibration and thermal cycling in plant environments.
- ✓Leonhardt process controller communication timeout and data loss — Firmware memory corruption, corrupt calibration tables, and serial port hardware failure prevent Leonhardt controllers from communicating with SCADA systems. Electrostatic discharge and power surge damage to optical isolation circuits interrupt protocol handshake.
- ✓Leonhardt temperature transmitter erratic readings and instability — Thermocouple reference junction compensation circuits degrade in Leonhardt transmitter modules due to capacitor aging and amplifier op-amp drift. Sensor cable shield deterioration introduces AC noise that destabilizes the signal conditioning stage.
- ✓Leonhardt legacy potentiometer setpoint control nonlinear and noisy — Carbon film potentiometers in older Leonhardt panels wear and develop resistance irregularities. Mechanical friction and contamination from plant dust cause intermittent contact and jump in output voltage during setpoint adjustment.

Frequently Asked Questions — LEONHARDT Repairs
Do you repair Leonhardt equipment anywhere in India?+
Yes. Synchronics repairs the complete Leonhardt product portfolio - process controllers, measurement systems, automation interfaces, and calibration instruments. We offer PAN-India scheduled pickup service from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, and all other major cities. All repair work is executed in our Vadodara, Gujarat facility with 48-hour turnaround for standard faults and comprehensive testing before dispatch.
What is the typical turnaround time for Leonhardt controller repair?+
Standard Leonhardt process controller repairs (relay replacement, firmware recovery, recalibration) typically complete within 48-72 hours from receipt. Complex faults requiring component sourcing or custom calibration protocols extend to 5-7 working days. We maintain expedited service for critical production line shutdowns - call our emergency hotline for same-day diagnostics and priority scheduling.
Do you repair older Leonhardt analog systems and legacy controllers?+
Yes, Synchronics specializes in repairing vintage and legacy Leonhardt analog modules still operating in mature Indian pharmaceutical and chemical plants. We maintain inventory of obsolete components including proprietary analog boards, relay cards, and potentiometer assemblies. Our engineers reverse-engineer circuit designs when original documentation is unavailable and provide drop-in replacements with identical electrical characteristics.
Can you recalibrate Leonhardt transmitters and validate measurement accuracy?+
Absolutely. Synchronics performs full factory-level calibration of all Leonhardt measurement instruments using certified reference standards traceable to national metrology labs. We validate temperature transmitters (PT100/thermocouple), pressure transducers, and level instruments across their operating ranges, document accuracy to within specification limits, and issue ISO-compliant calibration certificates. This is critical for pharmaceutical batch record compliance and GMP validation.
How do I know if my Leonhardt equipment needs repair or just recalibration?+
Contact Synchronics for free technical assessment. Our engineers will review your process logs, conduct non-destructive diagnostics, and advise whether simple recalibration restores performance or circuit repair is required. If your Leonhardt controller shows calibration drift, measurement fluctuations, communication dropouts, or setpoint instability, immediate inspection is recommended to prevent production losses and batch rejections in pharmaceutical or chemical operations.
How do I send my LEONHARDT 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 LEONHARDT 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 LEONHARDT 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 LEONHARDT 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.
