Industry Segments We Serve

Pumps and Foundry Industry (Peelamedu & Sidco Industrial Estate)

Coimbatore is a global hub for pump manufacturing and iron foundries, where maintaining precise temperature during metal casting and motor winding curing is essential for product quality. Thermocouples are the primary sensors for monitoring induction furnaces and curing ovens. The primary use case involves verifying the precise thermal profile of molten metal to prevent casting defects like cold shuts or uneven grain structure.

Textile Machinery and Processing (Pollachi & Tirupur Fringe)

The textile ecosystem in and around Coimbatore relies on Thermocouples for monitoring and regulating heat-setting, dyeing, and drying processes. The primary use case involves the precise measurement of temperatures in drying ovens and steam boilers where inaccurate thermal feedback can lead to material degradation, color inconsistency, or fire hazards in high-lint textile units. Inaccurate readings can lead to fiber degradation or significant material waste during production, impacting profitability. Vega Calibration acts as a vital technical partner by providing NABL-traceable calibration for these sensors, accounting for the unique electrical noise environments of the mills. We ensure your thermocouples operate with the high-resolution accuracy needed to maintain process stability. Our detailed calibration certificates provide the documented evidence required for global textile quality standards, ensuring your facility remains technically sound and audit-ready despite the high-lint conditions, protecting your brand's reputation.

Pharmaceuticals and Life Sciences (Saravanampatti & Coimbatore Fringe)

Coimbatore hosts significant pharmaceutical manufacturing and R&D units requiring strict compliance with USFDA and WHO-GMP standards. In these highly controlled environments, maintaining precise temperature measurement via thermocouples is fundamental to ensuring drug stability and preventing contamination during the formulation phases. A primary use case for these sensors is the thermal validation of autoclaves, depyrogenation tunnels, and stability chambers where a minor 0.5°C deviation can lead to catastrophic product batch failure or non-compliance during regulatory audits. Vega Calibration provides the technical soundness required through NABL-traceable calibration, ensuring that temperature monitoring data meets the requirements of ISO 17025. We ensure that your sensing systems are technically robust, protecting life-saving research and facilitating successful regulatory inspections by acting as your expert thought partner in thermal validation and audit-defense reporting in the 2026 cycle for international pharmaceutical export markets.

Automotive Component Manufacturing (Eachanari & Malumichampatti)

Coimbatore’s extensive automotive component sector utilizes Thermocouples for critical process control in plastic injection molding and metal hardening. The primary use case involves the precise monitoring of baking ovens for specialized coatings and the monitoring of component temperatures during hardening processes to ensure structural integrity and rust resistance. In the high-load production environments of Eachanari, electronic sensors are prone to terminal wear and signal sensitivity loss due to mechanical stress. Vega Calibration acts as a vital technical partner by ensuring these sensors are calibrated against simulated and comparison standards to detect thermal shifts with absolute precision. Our NABL-accredited processes help prevent defects and safeguard personnel, ensuring that your facility remains compliant with national safety standards. We provide the documented accuracy needed to maintain the metrological integrity of your production line, passing annual quality audits with technically sound data.

Frequently Asked Questions (FAQs)

Q: Why is my thermocouple reading drifting even after a few months of use?

A: This is often due to "Wire Inhomogeneity" or junction oxidation caused by Chandigarh's extreme seasonal temperature fluctuations and industrial dust. Regular NABL calibration at Vega helps identify this drift early, ensuring your process remains technically sound.

Q: Can Vega calibrate noble metal thermocouples (Type R, S) used in research labs?

A: Yes. We specialize in the calibration of Type R, S, and B thermocouples using high-temperature comparison methods, essential for the high-stakes research and engineering sectors in Chandigarh.

Q:WWhat is the difference between simulation and comparison calibration for thermocouples?

A: Simulation only checks the indicator, while Comparison Calibration (which we perform) checks the actual sensor wire in a thermal source. For a Quality Manager, comparison calibration is the only way to ensure the integrity of the sensing element for audit compliance.

Q: How often should thermocouples be recalibrated in harsh environments?

A: Typically every 6–12 months. High heat and chemical exposure accelerate drift, and regular NABL calibration at Vega helps catch errors early and maintain compliance.
