Industry Segments We Serve

Textile and Garment Manufacturing (Tirupur & Coimbatore Belt)

The textile industry, the backbone of the Tirupur and Coimbatore economy, relies heavily on thermal management. In spinning and weaving mills, high-speed motors and electrical panels operate 24/7, creating a high risk of electrical fires due to overheating. Thermal imaging calibration is essential here. Uncalibrated cameras might miss a 10°C rise in a motor bearing or a busbar joint, leading to catastrophic failure and weeks of downtime. Furthermore, in the dyeing and finishing stages, stenter machines require precise temperature profiles to ensure fabric sets correctly without scorching. A calibrated thermal camera ensures that the heat distribution across the fabric width is uniform. If the camera reads 150°C when the actual temperature is 165°C due to drift, the fabric may suffer from shade variation or decreased tensile strength, leading to export rejections. Vega ensures your cameras detect these subtle nuances accurately.

Foundries and Pump Manufacturing

Coimbatore is globally renowned for its pump sets and wet grinders, supported by hundreds of foundries in Thudiyalur and Maniyakaranpalayam. In metal casting, the temperature of molten iron or aluminum determines the metallurgical structure of the final product. Pouring metal at a temperature even slightly lower than the specification can cause cold shuts or porosity, rendering the casting useless. Thermal imaging cameras are used to monitor the ladle temperature and the cooling rate of the die. However, liquid metal has low and variable emissivity, which can trick uncalibrated cameras. Vega Calibrations provides specific calibration points at high temperatures (up to 1200°C) and advises on emissivity settings, ensuring that your quality engineers are making decisions based on reality, not optical artifacts. This prevents the mass production of defective castings and ensures the structural integrity of the pumps.

Electrical Transmission and Distribution

For power utility companies and private contractors maintaining substations in Palladam and Pollachi, thermal imaging is the primary line of defense against grid failure. High-voltage switchyards, transformers, and capacitor banks develop "hot spots" due to loose connections, oxidation, or load imbalances. These hot spots are precursors to arc flashes and explosions. A thermal camera used for these inspections must be calibrated to quantify the severity of the fault. A "Delta-T" (temperature difference) of 5°C might be a "monitor" status, while 20°C is an "immediate repair." If the camera is out of calibration, a critical 30°C rise might be under-reported as 10°C, leading the maintenance team to ignore a dangerous fault. Vega’s NABL-accredited calibration ensures that your safety audits are based on precise, defensible data, protecting both infrastructure and personnel.

Automotive Component Manufacturing

The automotive corridor stretching from Coimbatore to Salem and Erode houses numerous Tier-1 suppliers manufacturing gears, shafts, and braking components. Heat treatment processes like carburizing and induction hardening are critical for the fatigue life of these parts. Thermal imaging is used to verify that the induction heating coils are applying heat uniformly to the component geometry. An uncalibrated camera can lead to "soft spots" on a gear tooth or a shaft, which will fail prematurely under load in the vehicle. By utilizing Vega’s calibration services, automotive suppliers can guarantee that their thermal profiles meet the stringent requirements of IATF 16949. We ensure that the thermal cameras accurately capture rapid temperature changes during quenching processes, providing the data traceability required by global automotive OEMs.

Industrial Use Cases

Electrical Panel & Switchgear Audits (Preventive Maintenance)

The most common use case across Gandhipuram to Avinashi is the preventive maintenance of electrical panels. A calibrated thermal camera allows a technician to scan hundreds of connections in minutes. The specific use case involves identifying high-resistance joints caused by loose screws or corroded contacts. As current flows through this resistance, heat is generated. A calibrated camera allows the user to pinpoint the exact location of the heat source—whether it is the breaker lug, the crimp, or the wire itself. Use Case Criticality: Without calibration, the camera might show a "glow" but fail to accurately measure the temperature rise. Knowing the exact temperature is vital to classify the severity of the fault (Critical, Serious, or Minor) according to NETA (InterNational Electrical Testing Association) guidelines. Vega ensures your camera’s detector linearity is perfect so that temperature decisions are reliable.

Building Envelope & HVAC Diagnostics

In the commercial complexes of R.S. Puram and IT parks in Saravanampatti, energy efficiency is a major operational cost. Facility managers use thermal imaging to detect air leaks, missing insulation, and moisture intrusion in building facades. A calibrated camera can visualize the thermal bridge where cooled air is escaping or heat is entering. Specific Use Case: Detecting moisture accumulation in roof membranes before it drips into the server room. Water has a high thermal capacity and retains heat longer than the surrounding roof material. A thermal survey at sunset can reveal these damp spots. However, if the camera’s sensitivity (NETD) has degraded or it is out of calibration, it won't distinguish the slight temperature difference (often <1°C) of the moisture, leading to undetected leaks and costly structural damage.

Mechanical Friction & Bearing Analysis

In the heavy engineering sectors of Malumichampatti, thermal cameras are used to inspect conveyor rollers, motors, and gearboxes. The use case focuses on friction. When a bearing lacks lubrication or is misaligned, friction generates excess heat. A thermal camera can see this heat signature long before vibration analysis picks up the physical wobble. Specific Use Case: Monitoring the temperature of a high-speed CNC spindle. The spindle must operate within a specific thermal range to maintain machining precision. If it runs too hot, the metal expands, and the part tolerance is lost. Vega’s calibration ensures that the camera accurately reports the spindle housing temperature, allowing maintenance teams to re-grease or stop the machine before it seizes, saving lakhs in repair costs.

Process Temperature Profiling (Plastics & Rubber)

For the plastic molding industries in Kinathukadavu, maintaining the correct mold temperature is non-negotiable. Thermal cameras are used to take a "thermal snapshot" of the mold surface immediately after the part is ejected. This use case identifies blocked cooling channels inside the mold. If one side of the mold is 20°C hotter than the other, the plastic part will warp upon cooling. Use Case Specifics: Calibrated thermal imaging verifies the uniformity of the heater bands on injection molding barrels. An accurate temperature reading ensures the polymer flow is consistent. Vega Calibrations provides the confidence that the color gradients seen on the camera screen represent real temperature gradients, allowing process engineers to tune their cooling cycles for maximum efficiency and minimum scrap.

Compliance & Audit Requirements

In industrially advanced landscape, data integrity for temperature measurement is the key to passing inspections:

• ISO/IEC 17025:2017: This is the global standard for calibration. Our NABL accreditation guarantees that our results are traceable to the SI system, a mandatory requirement for any company undergoing an ISO 9001, IATF 16949, or AS9100 audit.

• FDA & GMP (Pharma): For pharmaceutical clients in Alandurai, 21 CFR compliances require that environmental monitoring tools be calibrated at set intervals. Uncalibrated thermal cameras used in storage validation can lead to Form 483 observations during FDA inspections.

• Insurance Audits: Many industrial insurers now require annual "Thermographic Audits" of electrical panels to renew fire insurance policies. These audits must be performed using calibrated cameras to be valid.

Frequently Asked Questions (FAQs)

Q: How often should I calibrate my thermal camera in Bahrain?

A: Most manufacturers (like FLIR and Fluke) and standards (ISO) recommend calibration once every 12 months. However, if the camera is used in harsh environments (high dust, vibration) found in foundries or textile mills, a 6-month interval may be safer to ensure accuracy.

Q: Can you calibrate all brands of thermal cameras?

A: Yes, Vega Calibrations handles all major brands including Flir, Fluke, Testo, Hikvision, and Keysight. We calibrate the optical system and detector regardless of the manufacturer.

Q: Do you provide pickup and drop services in Coimbatore?

A: We have a strong logistics network covering Coimbatore, Peelamedu, Gandhipuram, and nearby industrial towns like Tirupur and Erode. We can arrange secure logistics to transport your high-value instruments to our central lab and back.

Q: My camera has a "self-calibration" or NUC button. Do I still need lab calibration?

A: Yes. The "NUC" (Non-Uniformity Correction) button only resets the internal drift relative to the camera's own shutter. It does not verify the absolute temperature accuracy against a known standard. Only a lab calibration with a Blackbody can ensure true temperature measurement.
