COMPUR Product Lines We Repair
Our engineers are trained on the full COMPUR product range. Below are the major product families we service.
COMPUR Radiation Pyrometers (Fixed and Portable)
Non-contact temperature measurement instruments using optical radiation detection. Common issues include lens contamination, sensor drift, calibration loss, and optical window fogging. Furnace monitoring accuracy degrades over 12-18 months requiring professional recalibration and cleaning.
Two-Colour and Multi-Spectral Pyrometers
Advanced measurement systems for high-temperature furnaces where emissivity varies. These detect radiation at two wavelengths simultaneously to compensate for surface emissivity changes. Repair typically involves spectral filter alignment, PMT/detector replacement, and wavelength calibration.
COMPUR Optical Measurement Electronics and Transmitters
Signal conditioning and transmission modules that convert pyrometer optical signals to 4-20mA or digital outputs. Common failures include input amplifier drift, output card faults, and communication module failure. Requires component-level diagnostics and precision calibration.
COMPUR Optical Lens and Filter Assemblies
Precision optical components including sapphire windows, infrared filters, and lens systems for harsh furnace environments. Thermal cycling and dust accumulation cause optical transmission loss. Synchronics performs optical cleaning, anti-reflection coating restoration, and replacement assembly supply.
COMPUR Temperature Monitoring Control Systems
Integrated systems combining pyrometer sensors, signal processing, alarm relays, and display units for furnace temperature automation. Failures include relay board damage, calibration offset, and sensor input module malfunction requiring full system diagnostics and reprogramming.

Common COMPUR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COMPUR equipment arriving at our workshop.
- ✓Optical lens contamination and coating degradation — Furnace dust, thermal cycling, and moisture ingress degrade sapphire window anti-reflection coatings. Over 12-18 months of continuous operation in steel mills and foundries, optical transmission loss causes temperature reading errors of 20-50°C.
- ✓Sensor drift and temperature measurement offset — Detector aging (photomultiplier tube or photodiode degradation) and amplifier component drift cause calibration errors. COMPUR pyrometers lose accuracy after 2-3 years without recalibration, drifting 10-30°C across the measurement range.
- ✓Electronics module communication and output failure — Thermal stress on printed circuit boards, solder joint fatigue, and component failure in COMPUR signal processors and transmitters. Failure modes include loss of 4-20mA output, erratic digital readings, and unresponsive alarm relays in high-temperature environments.
- ✓Spectral filter misalignment in two-colour pyrometers — Mechanical vibration from foundry equipment and thermal cycling cause wavelength-selective filter stacks to misalign. This introduces measurement errors in emissivity-compensated readings, making the two-colour advantage ineffective for furnace control.
- ✓No display or intermittent indicator readings on pyrometer — Display connector corrosion, display module LCD failure, or internal wiring degradation in COMPUR optical pyrometer heads. Poor electrical contact in harsh furnace environments causes intermittent temperature readings and alarm malfunction.
- ✓Calibration loss and unreliable temperature control feedback — COMPUR pyrometer calibration degrades due to age, optical contamination, or power supply instability. Manufacturing lines relying on pyrometer feedback experience temperature runaway or inadequate heating in furnaces, compromising product quality and yield.

Frequently Asked Questions — COMPUR Repairs
Do you repair COMPUR equipment anywhere in India?+
Yes. Synchronics repairs the full COMPUR product range — radiation pyrometers, two-colour pyrometers, optical sensors, measurement electronics, and signal transmitters. We offer PAN India door pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Jaipur, and all other industrial cities. Central facility in Vadodara, Gujarat with optical calibration benches and blackbody test sources.
What is COMPUR pyrometer calibration and why does it need recalibration?+
COMPUR pyrometers measure furnace temperature by detecting infrared radiation. Calibration maps the sensor's electrical output to actual temperature. Over 12-24 months of continuous furnace operation, optical contamination and detector aging cause calibration drift of 10-50°C. Synchronics recalibrates against certified blackbody sources to restore measurement accuracy and maintain your furnace process control within ±2% tolerance.
Can you repair COMPUR optical lens and sapphire window assemblies?+
Yes. Synchronics specializes in COMPUR optical component restoration including sapphire window cleaning, anti-reflection coating inspection, and protective lens replacement. We clean contamination from furnace dust, verify optical transmission using test benches, and supply genuine COMPUR window assemblies. Most optical head repairs are completed in 5-7 working days.
My COMPUR pyrometer shows erratic temperature readings in the control room. What's wrong?+
Erratic readings typically indicate sensor contamination, electronics module drift, or connector corrosion. COMPUR pyrometers are sensitive to dust and moisture in furnace environments. Synchronics diagnoses the fault using diagnostic test equipment, cleans the optical head, recalibrates sensors, and replaces corroded connectors. We verify stability across your furnace's full operating range before return.
How long does COMPUR pyrometer repair typically take at Synchronics?+
Standard optical cleaning and calibration takes 3-5 working days. Component replacement (PMT tube, electronics repair) takes 7-10 days. Urgent repairs can be expedited to 48 hours for critical furnace control applications. We maintain a stock of common COMPUR parts in Vadodara and offer same-week turnaround for most steel mills and foundries across Gujarat, Maharashtra, and Madhya Pradesh.
How do I send my COMPUR 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 COMPUR 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 COMPUR 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 COMPUR 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.
