CAMBRIDGE Product Lines We Repair
Our engineers are trained on the full CAMBRIDGE product range. Below are the major product families we service.
Cambridge PID Temperature Controllers
Standalone and panel-mount PID controllers for precise thermal process management. Common failures include stuck output relays, erratic temperature readings due to sensor signal conditioning faults, and calibration drift in the analog control circuitry affecting setpoint accuracy.
Cambridge Thermocouple Input Modules
Modular signal conditioning units for K, J, T, and E type thermocouple inputs with cold-junction compensation. Typical faults include millivolt amplifier failures, cold-junction sensor degradation, and input isolation module breakdown causing measurement errors.
Cambridge RTD Transmitters
Precision Pt100 and Pt1000 resistance temperature detector signal converters with 4-20mA and digital outputs. Common issues include bridge circuit imbalance, excitation current source failures, and output linearity errors in high-temperature applications.
Cambridge Process Data Loggers
Multi-channel temperature and pressure recording systems with onboard memory and USB connectivity for GMP-compliant documentation. Failures often involve SD card interface corruption, real-time clock battery exhaustion, and USB communication protocol errors.
Cambridge Thermal Regulation Boards
Embedded control PCBs for heating element management, fan speed regulation, and freeze-protection sequencing in process equipment. Typical repairs address MOSFET driver failures, thermistor interface shorts, and firmware calibration parameter corruption.
Why Choose Synchronics for CAMBRIDGE 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 CAMBRIDGE equipment.

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 CAMBRIDGE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CAMBRIDGE equipment arriving at our workshop.
- ✓Temperature reading stuck or drifting uncontrollably — Cambridge RTD or thermocouple input buffer amplifier failure, or cold-junction compensation sensor degradation in thermocouple modules. Common in harsh plant environments where sensor leads corrode.
- ✓PID output relay chattering or refusing to energize — Electromagnetic relay coil winding opens or contact pits accumulate due to repeated switching of inductive heating loads. Cambridge controllers often drive high-current contactor circuits without adequate snubbing.
- ✓No communication on Modbus or Hart interface — Optoisolator failure in the isolated RS-485 transmitter stage of Cambridge data logger or RTD transmitter modules, or firmware bootloader corruption preventing protocol handler initialization.
- ✓Setpoint changes not registering or display shows corrupted values — EEPROM data corruption in Cambridge controller's non-volatile memory, often triggered by power supply transients or inadequate filtering on the 5V rail. Can also stem from front-panel membrane switch matrix failures.
- ✓4-20mA output stuck at minimum or maximum current — Output current DAC (digital-to-analog converter) failure in Cambridge RTD transmitter or process controller, or precision resistor network drift in the I-V conversion stage caused by thermal cycling.
- ✓Calibration offset or scale factor errors persist after user adjustment — Non-volatile memory write-protect fuse blown due to power surge, or temperature coefficient trimmers physically loose on Cambridge analog conditioning board, causing calibration drift during thermal transients.

Frequently Asked Questions — CAMBRIDGE Repairs
Do you repair Cambridge equipment anywhere in India?+
Yes, absolutely. Synchronics repairs the complete Cambridge product range — PID controllers, RTD transmitters, thermocouple input modules, data loggers, and thermal regulation boards. We offer PAN India door pickup from Mumbai, Pune, Delhi, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all tier-1 and tier-2 cities. Our central facility in Vadodara, Gujarat processes repairs and returns units with full documentation within 3-5 working days.
What should I do if my Cambridge PID controller loses temperature setpoint on power cycle?+
This typically indicates EEPROM (non-volatile memory) failure in the Cambridge controller. Do not attempt repeated power cycling as this can worsen data corruption. Contact Synchronics immediately — we will back up your calibration constants using Cambridge's serial bootloader protocol, replace the affected memory chip if needed, and reprogram with your original configuration. We provide a certificate of recalibration upon return.
How long does Cambridge thermocouple module repair usually take?+
Cambridge thermocouple input modules are among the fastest repairs. Cold-junction sensor replacement or amplifier IC substitution typically requires 4-6 hours bench time. Synchronics returns thermocouple modules within 24-48 hours of receipt, with full cold-junction compensation verification against a calibrated reference junction.
Can you repair Cambridge RTD transmitters with Hart or Modbus output?+
Yes. Synchronics has deep expertise with Cambridge Hart and Modbus RTD transmitters, including optoisolator replacement for communication failures and Hart EEPROM reprogramming. We also upgrade older Hart v5 modules to Hart v7 compatible firmware if you need improved cloud integration with IIoT platforms used in Indian manufacturing.
Do you offer Cambridge controller recalibration and documentation?+
Yes. Every Cambridge repair includes full recalibration against certified reference standards. We provide IEC 61010-1 compliant calibration certificates with traceability to national standards, mandatory for pharmaceutical and food processing QA audits. Synchronics also provides GMP-compliant repair documentation (root cause, parts replaced, test results) required for FDA warning letter prevention.
How do I send my CAMBRIDGE 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 CAMBRIDGE 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 CAMBRIDGE 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 CAMBRIDGE 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.
