Industry Segments We Serve

Pharmaceutical & Biotechnology Sector

In the pharmaceutical hubs of Palghar, Boisar, and Navi Mumbai, strict adherence to thermal standards is non-negotiable. This industry relies heavily on RTD PT-100 sensors because of their high linearity and stability compared to thermocouples. The calibration of these sensors is critical for maintaining the efficacy of Active Pharmaceutical Ingredients (APIs) and finished formulations. A drift of even 0.5°C in a stability chamber or an incubator can lead to out-of-specification (OOS) results, potentially causing batch rejections costing millions. Furthermore, regulatory bodies like the USFDA and CDSCO mandate that all thermal controlling instrumentation be calibrated at defined intervals with traceable standards. Vega’s services ensure that pharmaceutical companies can confidently present their calibration certificates during audits, proving that their critical process parameters (CPPs) such as sterilization temperatures and storage conditions are under strict control.

Food & Beverage Processing

The Food and Beverage industry, thriving in areas like Bhiwandi and Vasai, operates under stringent food safety management systems like FSSAI and HACCP. Temperature control is the backbone of food safety, determining the success of processes like pasteurization, sterilization, and cold chain storage. RTD PT-100 sensors are ubiquitous in this sector, monitoring everything from the temperature of milk in dairy processing to the baking temperature in industrial ovens. If a sensor reads incorrectly, it could lead to under-cooked products that harbor dangerous bacteria or over-cooked products that fail quality checks. Our calibration services provide the assurance that the Critical Control Points (CCPs) identified in your HACCP plan are monitored accurately. By verifying the accuracy of these sensors, we help manufacturers prevent spoilage, extend shelf life, and protect public health, ensuring compliance with both local and international food safety standards.

Automotive & Heat Treatment

The automotive manufacturing belts in Pune, Chakan, and Taloja utilize complex heat treatment processes to harden engine components and chassis parts. In this sector, the mechanical properties of metals—such as hardness, tensile strength, and fatigue life—are directly determined by the precision of the heat treatment cycle (annealing, quenching, tempering). RTD PT-100s and thermocouples are used to control these furnaces. Compliance with standards like AMS2750 (Pyrometry) and CQI-9 is often required by OEMs. These standards mandate rigorous calibration of the temperature controllers and sensors to ensure thermal uniformity within the furnace. A deviation in temperature reading can result in parts that are too brittle or too soft, leading to catastrophic failure in the field. Vega provides the high-accuracy calibration required to meet these rigorous automotive quality standards, ensuring that every gear and axle meets the design specifications.

Logistics & Cold Chain Warehousing

With Bhiwandi being a massive logistics hub for India, the warehousing sector is a primary user of temperature monitoring solutions. Cold chain logistics for pharmaceuticals, perishable foods, and frozen goods rely on maintained temperatures to prevent degradation. Warehouses utilize networks of RTD sensors and data loggers to monitor ambient conditions 24/7. If these sensors drift, a warehouse might be running warmer than the displayed temperature, ruining sensitive inventory like vaccines or frozen seafood. Calibration ensures that the monitoring system provides a true reflection of the storage environment. This is critical for meeting GDP (Good Distribution Practice) guidelines. Vega supports this sector by calibrating the master sensors used to validate building management systems (BMS) and reefer trucks, ensuring the integrity of the supply chain from the warehouse to the final consumer.

Industrial Use Cases

Autoclave Sterilization Validation

In pharmaceutical manufacturing and hospitals across Mumbai and Thane, autoclaves are used to sterilize equipment and products using high-pressure saturated steam. The standard sterilization cycle (e.g., 121°C for 15 minutes) relies entirely on the accuracy of the RTD PT-100 measuring the chamber temperature. If the sensor reads 121°C but the actual temperature is 120.5°C, the sterilization may be incomplete, leaving behind viable biological agents. This is a critical safety risk. Use Case: A Quality Manager uses Vega’s calibration services to verify the autoclave’s controlling RTD and the independent recording RTD. We ensure that both sensors are reading within ±0.5°C of the reference standard. This calibration data is then used in the annual re-validation report (PQ) of the autoclave, satisfying auditors that the sterilization cycle is effective and the final product is sterile and safe for patient use.

Cold Storage & Walk-In Coolers

Large distribution centers in Bhiwandi and Panvel operate massive walk-in cold rooms to store temperature-sensitive goods between 2°C to 8°C. These rooms are controlled by a central BMS linked to multiple PT-100 sensors. Use Case: Over time, the sensors near the evaporator coils may drift due to moisture ingress or thermal cycling. A facility manager engages Vega to perform an on-site calibration of these control sensors. We place our reference sensors adjacent to the facility’s sensors and record the deviation. If a sensor is found to be reading 4°C when the actual temperature is 6°C, the facility is at risk of exceeding the 8°C upper limit without knowing. Our calibration certificate allows the facility manager to apply offsets in the BMS, correcting the error and ensuring the room remains strictly within the 2-8°C window, thus preventing product spoilage and financial loss.

Industrial Oven Heat Distribution

Manufacturing units in Rabale and Mahape use conveyor ovens for curing coatings or drying components. These ovens often have multiple heating zones, each controlled by an individual loop. Use Case: A manufacturer notices color variation in their powder-coated products, suspecting temperature inconsistency. They hire Vega to calibrate the temperature controllers and sensors in each zone. We identify that the RTD in Zone 3 has drifted by -5°C, causing the controller to overheat that zone to compensate for the falsely low reading. By calibrating and adjusting the loop, we restore the temperature balance across the oven. This resolves the quality issue, ensures uniform curing of the powder coat, and reduces energy waste caused by overheating, directly impacting the plant's operational efficiency and product quality.

Chemical Reactor Temperature Control

In the chemical zone of Dombivli, precise temperature control is vital for reaction yield. A specialized polymer reactor requires a steady temperature of 150°C to ensure the correct molecular weight of the polymer. Use Case: The plant engineers utilize a Class A PT-100 sensor for this critical loop. However, due to the vibration of the agitator, the sensor calibration can shift. Vega performs a loop calibration, injecting simulated resistance values corresponding to 150°C into the controller to verify the electronics, and calibrating the sensor itself in a dry block. We certify that the entire loop is accurate to within ±0.2°C. This granular level of accuracy allows the chemical engineers to optimize the reaction time and maximize the yield of the high-value polymer, ensuring consistent product grade and minimizing waste by-products.
