Industry Segments We Serve

Pharmaceutical & Biotechnology

In the pharmaceutical hubs around Alandur and Ekkaduthangal, precision is a regulatory mandate, not a choice. The manufacturing of life-saving drugs, vaccines, and biologics relies heavily on strict temperature control. Any deviation in temperature measurement can lead to the formation of impurities, degradation of active pharmaceutical ingredients (APIs), or complete batch failure. RTD PT-100 sensors are the industry standard here due to their high stability and linearity. For companies operating under strict GMP (Good Manufacturing Practice) guidelines, regular calibration ensures that every step—from raw material storage to final formulation—maintains the validated state. Our services help these industries navigate complex audits by providing calibration certificates that meet the stringent documentation standards of global regulatory bodies. We understand that in pharma, a sensor error of even 0.5°C can result in a warning letter or a recall, making our high-precision services critical for business continuity.

Automotive & Manufacturing

Chennai is known as the "Detroit of India," with massive automotive clusters in Oragadam and Vallam Vadagal. The automotive industry utilizes thermal processing for various critical components, including engine parts, braking systems, and safety glass. Heat treatment processes such as annealing, hardening, and tempering require precise temperature profiles to achieve the desired material properties like hardness and ductility. If the PT-100 sensors controlling these furnaces drift, the metal structure may become brittle or too soft, leading to catastrophic component failure in vehicles. Beyond metallurgy, the curing of paint and coatings in large industrial ovens also demands uniform temperature distribution, monitored by calibrated sensors. Vega’s calibration services ensure that automotive manufacturers meet the rigorous IATF 16949 standards, providing the confidence that every part rolling off the assembly line has been processed within exact thermal specifications.

Food & Beverage Processing

The Food Safety and Standards Authority of India (FSSAI) mandates strict temperature controls to prevent microbial growth and ensure public safety. For food processing units in Ambattur Industrial Estate and Madhavaram, maintaining the "Cold Chain" is vital. RTD sensors are used to monitor pasteurization temperatures, fermentation tanks, and deep-freezing units. In processes like milk pasteurization, the temperature must be held at exactly 72°C for 15 seconds; a sensor reading lower than the actual temperature could fail to kill harmful bacteria (e.g., Salmonella), while a reading higher could scorch the product and ruin its taste. Our calibration services help food and beverage companies verify that their Critical Control Points (CCPs) are under control, adhering to HACCP (Hazard Analysis Critical Control Point) plans. We ensure that your thermal instruments are accurate, helping you avoid spoilage, waste, and regulatory penalties.

Chemical & Petrochemical

The chemical industries located in Manali and Ennore deal with volatile and hazardous reactions where temperature is a key variable for reaction kinetics and safety. Exothermic reactions, if not monitored precisely by accurate PT-100 sensors, can lead to thermal runaway incidents, posing severe safety risks to the plant and personnel. Furthermore, in distillation columns and reactors, precise temperature control determines the purity of the final chemical product. A drifting sensor can lead to inefficient separation, resulting in off-spec products that must be reprocessed or discarded, costing the company significant revenue. Vega’s calibration services for explosion-proof and intrinsic safety RTDs ensure that chemical plants operate within their safe operating limits. We provide the traceability required for safety audits and process optimization, ensuring that complex chemical synthesis proceeds exactly as designed.

Industrial Use Cases

Autoclave Sterilization Verification (Pharma)

In pharmaceutical manufacturing facilities near Guindy, autoclaves are used to sterilize equipment, vials, and surgical instruments. The standard sterilization cycle requires maintaining steam at 121°C for a specific duration to ensure the destruction of all microbial life, including spores. The autoclave relies on PT-100 sensors to control this temperature. Use Case: If the control sensor reads 121°C but the actual temperature is 119°C due to drift, the load may not be sterile, leading to a "non-sterile" batch release which is a critical violation of FDA guidelines. Conversely, if the sensor reads low, the autoclave might overheat, damaging sensitive plastic components or rubber stoppers. Vega’s calibration service verifies these sensors against a high-precision standard, ensuring the F0 value (lethality factor) calculated by the autoclave controller is accurate, thus guaranteeing patient safety.

Heat Treatment Furnace Control (Automotive)

Consider a gear manufacturing unit in Sriperumbudur that performs carburizing on steel gears to increase surface hardness. This process requires the furnace to be maintained at approximately 900°C - 950°C. Use Case: The furnace uses heavy-duty RTDs or thermocouples for control. If the sensor is out of calibration by even 10°C, the carbon diffusion depth into the steel will be incorrect. If the temperature is too low, the gear teeth will be soft and wear out prematurely; if too high, they may become brittle and crack under load. Regular calibration ensures that the thermal cycle experienced by the metal matches the metallurgical recipe exactly. Vega provides on-site calibration for these high-temperature applications, minimizing the downtime of critical production furnaces and ensuring the mechanical integrity of the automotive components.

Cold Storage & Blast Freezing (Food Industry)

A seafood export company in Royapuram uses blast freezers to rapidly freeze fish to -40°C to preserve freshness and texture. Use Case: The blast freezer controller uses a PT-100 probe to determine when the core temperature of the product has reached the safe limit. If this probe drifts and reads -40°C when the product is actually only at -30°C, the freezing process might stop prematurely. This incomplete freezing allows ice crystals to grow larger (damaging the tissue) and may not stop enzymatic activity, leading to spoilage during export transit. Our calibration services validate these low-temperature sensors, ensuring they are accurate at critical setpoints like -18°C and -40°C, thereby protecting the value of high-cost export consignments.

Stability Chamber Monitoring (R&D Labs)

Research laboratories in Taramani and Velachery conduct stability studies to determine the shelf life of new drug formulations. These samples are stored in stability chambers at specific conditions, such as 25°C/60%RH or 40°C/75%RH, for months or years. Use Case: A PT-100 sensor continuously monitors the chamber temperature. If the calibration of this sensor is off, the entire long-term study could be invalidated. For example, if the chamber was actually running at 42°C instead of 40°C because of a sensor error, the drug might degrade faster than expected, leading to an artificially short shelf life on the label. Vega’s calibration ensures that the environmental conditions recorded during these expensive and time-consuming studies are accurate and legally defensible during regulatory audits.
