CHESSELL Product Lines We Repair
Our engineers are trained on the full CHESSELL product range. Below are the major product families we service.
Chessell Chart Recorders (Potentiometric)
Continuous strip chart recorders for temperature, pressure, and multi-channel process logging. Common issues include pen arm friction, servo motor calibration drift, paper feed mechanism wear, and ink supply contamination affecting trace clarity.
Chessell Electromechanical Drives
Stepper motor and servo drive systems powering chart paper feed and pen positioning in legacy recorders. Typical faults include stepper coil burnout, timing belt degradation, and encoder signal loss affecting chart synchronisation.
Chessell Analogue Signal Conditioning
Thermocouple and millivolt input modules providing galvanic isolation and amplification for process signals. Common failures involve cold junction compensation drift, input module isolation breakdown, and DIN rail connector oxidation.
Chessell Digital Data Loggers
Battery-backed solid-state logging units for archival and remote data storage in pharmaceutical GMP environments. Issues include lithium battery degradation, SD card wear-out, and Bluetooth module intermittent connection in networked variants.
Chessell Calibration Standards
Precision reference instruments and calibration cells for validating recorder accuracy in controlled laboratory conditions. Common wear points include precision resistor element tolerance drift and battery terminal corrosion.
Why Choose Synchronics for CHESSELL Repairs?

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 CHESSELL 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 CHESSELL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CHESSELL equipment arriving at our workshop.
- ✓Chart recorder pen not marking or faint trace — Chessell pen mechanism failures typically stem from ballpoint tip wear, dried ink cartridge, or mechanical binding in the pen arm pivot due to paper dust accumulation and humidity-induced corrosion.
- ✓Chart paper feed motor stalls or feeds intermittently — Chessell stepper motors driving paper feed often fail due to winding insulation breakdown from thermal cycling near furnaces, or paper jam damage to the gear train coupling the motor shaft to the paper drive roller.
- ✓Erratic or drifting trace on multi-channel recorder — Chessell multi-channel systems experience servo loop instability when potentiometer wiper contact resistance increases due to dust and humidity, or when the feedback mechanism encounters stiction in the mechanical linkage.
- ✓Thermocouple input module showing constant offset or zero error — Chessell analogue input cards develop reference voltage drift when their precision resistor networks age, or fail thermally when DIN rail connectors make intermittent contact causing resistive heating.
- ✓Digital data logger fails to store or retrieve records — Chessell solid-state loggers experience data corruption when lithium backup batteries deplete, causing EEPROM write cycle loss. SD card file system errors also occur after thermal shock or vibration-induced contact bounce.
- ✓Calibration unit reads inconsistently or battery depletes rapidly — Chessell calibration standards suffer reference cell performance loss when precision resistor elements age or when battery contacts corrode, causing intermittent contact resistance that destabilises output voltage.

Frequently Asked Questions — CHESSELL Repairs
Do you repair Chessell equipment anywhere in India?+
Yes. Synchronics repairs the full Chessell product range — chart recorders, data loggers, signal conditioning modules, and calibration standards. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata and all other industrial cities. All repairs are completed in our ISO 9001 certified facility in Vadodara, Gujarat, with same-day receipt-to-diagnostics turnaround.
Do you repair legacy Chessell potentiometric recorders from the 1980s and 1990s?+
Absolutely. Chessell mechanical chart recorders built from the 1970s onwards remain fully serviceable. We maintain an inventory of spare pen mechanisms, servo motor brushes, coupling components, and paper feed assemblies. Even if specific Chessell modules are obsolete, our engineers custom-fabricate mechanical replacements or propose proven electronic alternatives that integrate seamlessly with your existing setup.
Can Synchronics calibrate Chessell recorders to pharmaceutical GMP standards?+
Yes. Our calibration service is documented for FDA, EMA, and Indian pharmaceutical compliance. We use traceable reference standards and provide ISO 17025 calibration certificates. All work is recorded in batch validation protocols required for Annex 15 compliance. We can also establish recalibration intervals and maintain logbooks for regulatory inspections.
What is the typical turnaround time for Chessell recorder repairs?+
Routine repairs (pen replacement, paper feed motor, servo calibration) are completed within 5-7 business days. Complex diagnostics (multi-channel synchronisation faults, electronics module replacement) require 10-14 days. We provide daily status updates and expedited return shipping at no extra cost for critical manufacturing environments.
Do you offer Chessell equipment modernisation or conversion to digital data logging?+
Yes. We can retrofit legacy Chessell potentiometric recorders with plug-compatible digital data loggers that read the same analogue signals. This preserves your existing thermocouple and transducer infrastructure while providing cloud-based data archival, alarms, and regulatory reporting. We also supply wireless Chessell BluLog modules for retrofit applications where cabling is difficult.
How do I send my CHESSELL 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 CHESSELL 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 CHESSELL 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 CHESSELL 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.
