Industry Segments We Serve

Pharmaceuticals and Life Sciences (Changodar, Sanand & Bavla)

Ahmedabad is a global headquarters for pharmaceutical innovation, housing major domestic and international laboratories that require strict compliance with USFDA and WHO-GMP standards. In these highly controlled environments, maintaining precise temperature control is fundamental to ensuring drug stability and preventing contamination during the formulation phases. A primary use case for Digital Temperature Controllers here is the regulation of stability chambers, incubators, and autoclaves 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 control data meets the requirements of ISO 17025 and Schedule M standards. We ensure that your control 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.

Chemicals and Petrochemicals (Vatva, Naroda & Odhav)

The industrial estates in Ahmedabad manage volatile and exothermic reactions that require absolute thermal vigilance. Digital Temperature Controllers serve as indispensable safety tools for regulating the temperature of reactors, boilers, and high-pressure steam lines. The critical use case involves the precise control of chemical reactions where inaccurate temperature regulation could lead to runaway conditions, fugitive emissions, or catastrophic equipment failure. Vega Calibration acts as a vital technical partner by ensuring these controllers are calibrated against simulated standards to detect even minor electronic drift caused by the aggressive chemical atmosphere. Our NABL-accredited processes help prevent hazardous incidents and safeguard personnel, ensuring that your facility remains compliant with the Gujarat Pollution Control Board (GPCB) and the Factory Act, 1948. We uphold the metrological integrity of your safety systems, helping you pass rigorous annual safety audits with technically sound data and clear traceability chains.

Automotive and Engineering (Sanand Industrial Estate)

As a premier automotive hub, Sanand’s manufacturing units rely on Digital Temperature Controllers for critical process control in paint shops, engine assembly, and heat treatment. The primary use case involves the precise regulation of curing ovens and hardening furnaces where a deviation of even 1°C can lead to paint defects or compromised structural integrity of engine components. In the high-vibration environment of Sanand, electronic controllers are prone to signal noise and internal drift. Vega Calibration acts as a vital technical partner by ensuring these controllers are calibrated against simulated standards to detect even trace electronic shifts with absolute precision. Our NABL-accredited processes help prevent production rejections and safeguard personnel, ensuring that your facility remains compliant with international IATF 16949 standards and passing rigorous annual safety and quality audits with technically sound data and clear traceability.

Textiles and Dyes Manufacturing (Naroda & Ahmedabad Fringe)

The traditional textile and dye industry in Ahmedabad relies on Digital Temperature Controllers for monitoring and regulating heat-setting, dyeing, and drying processes. The primary use case involves the precise regulation of drying ovens and steam boilers where inaccurate thermal control can lead to material degradation, color inconsistency, or fire hazards in high-dust textile units. Inaccurate readings can lead to fiber degradation or significant material waste during production. Vega Calibration acts as a vital technical partner by providing NABL-traceable calibration for these sensors and controllers, accounting for the unique electrical noise environments of the mills. We ensure your controllers 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.

Industrial Use Cases

Food Processing and Cold Storage (Aslali & Bavla Corridor)

The industrial corridor surrounding Ahmedabad hosts significant food processing and cold storage units where maintaining sterile temperature ranges is a safety mandate under HACCP and FSSAI guidelines. The primary use case for Digital Temperature Controllers is the precise regulation of industrial freezers, pasteurizers, and cooking vessels to prevent cross-contamination and bacterial growth. Inaccurate temperature control can lead to biological risks and product spoilage, which is especially critical during Ahmedabad’s intense summer heat. Vega provides the low-uncertainty calibration required to support these high-stakes hygienic requirements. By providing technically sound calibration data, we help food processors manage the risks associated with thermal deviations, ensuring that every operation meets the rigorous quality benchmarks expected by both domestic consumers and global export standards. Our NABL-accredited certificates provide the documented accuracy needed to maintain brand reputation and satisfy health and safety audits by the FSSAI.

Power Plants, Utilities, and Electrical Panels (Ahmedabad & Surrounding Industrial Zones)

Thermal stability is a critical safety and reliability requirement in power generation units, substations, and industrial electrical panels across Ahmedabad. Digital Temperature Controllers are extensively used to regulate transformer oil heaters, panel cooling systems, and auxiliary equipment where overheating can lead to insulation breakdown, arc faults, or unplanned shutdowns. The primary risk lies in controller drift caused by continuous electrical load and ambient heat. Vega Calibration provides NABL-traceable calibration against simulated reference standards to verify controller accuracy across operating ranges. Our calibration ensures compliance with ISO 9001, ISO 45001, and electrical safety audit requirements, delivering technically defensible data that supports preventive maintenance programs and minimizes operational risk.

Frequently Asked Questions (FAQs)

Q: Why does my temperature controller show a 'Sensor Break' error even with a connected probe?

A:This can be due to a failure in the controller's internal input module or a high-resistance contact in the terminal block, common in seasonally dusty environments. Our NABL calibration includes a thorough terminal check and electronic validation to ensure the input circuitry is functioning correctly.

Q:How often should I calibrate the controllers in my Changodar-based pharma unit?

A: Given the sensitivity of healthcare products and international oversight (FDA/WHO), we recommend an annual calibration cycle. For critical stability chambers, a 6-month interval is technically sound to prevent drift-related non-conformities during safety audits.

Q:Can Vega calibrate the PID parameters of my temperature controller?

A: Calibration primarily focuses on input/output signal accuracy. However, our technical team can assist in verifying that the controller accurately interprets these signals to maintain the PID logic, ensuring technically sound process control for your facility.

Q:Why do my temperature readings fluctuate even when the process is stable?

A: This is usually due to electrical noise, loose terminals, or sensor drift. During NABL calibration, we check signal stability and terminal integrity to ensure consistent and reliable readings.
