Industry Segments We Serve

Pharmaceuticals and Biotechnology

Hyderabad is the "Vaccine Capital of the World," and units in Genome Valley and Miyapur rely heavily on RTD PT-100 sensors for critical process monitoring. The pharmaceutical segment requires absolute precision because even a 0.5°C deviation in a stability chamber or bioreactor can compromise a multi-million dollar batch of life-saving drugs. Vega provides specialized NABL-accredited services to these units, ensuring that their cold storage, fermenters, and autoclaves operate within validated limits. Our calibration certificates provide the "As-Found" and "As-Left" data necessary to satisfy global regulatory bodies like the USFDA and EMA. By partnering with Vega, pharma giants in Bollaram can maintain the highest standards of product safety while ensuring their thermal sensors are resistant to drift during long-term stability studies, thereby protecting the integrity of their clinical research.

Food and Beverage Processing

In the food processing sectors located around Cherlapally and Uppal, temperature control is the primary defense against microbial growth and spoilage. RTD PT-100 sensors are used extensively in pasteurizers, blast freezers, and industrial ovens to ensure that food products reach the required "kill temperature" or are stored at safe sub-zero levels. Vega understands the rigor of HACCP and FSSAI audits; therefore, our calibration services focus on the sensor's accuracy at critical control points (CCPs). We provide rapid onsite calibration to minimize downtime for high-volume production lines. Whether it’s a dairy unit in Secunderabad or a frozen food exporter in Shamshabad, Vega’s precise thermal validation ensures that your temperature sensors are accurate, helping you avoid product recalls and maintain a consistent brand reputation for quality and safety.

Automotive and Heavy Engineering

The automotive manufacturing clusters in Medak and the engineering hubs of Kothaguda utilize RTD sensors for heat treatment, engine testing, and climate-controlled painting booths. In these environments, RTDs must withstand extreme thermal cycling and mechanical vibration without losing their calibration. Vega’s technicians are experts in calibrating heavy-duty industrial RTDs used in furnaces and specialized testing rigs. We ensure that your temperature controllers are perfectly synced with the sensors to maintain uniform heating during the tempering or annealing of critical engine components. Our services help automotive OEMs and their Tier-1 suppliers maintain ISO 9001 and IATF 16949 compliance. By delivering precise calibration near Ameerpet and other logistics hubs, we help manufacturers reduce energy consumption and improve the structural integrity of their engineered products through exact thermal management.

Chemical and Petrochemical Industry

The chemical manufacturing zones in Bicholim and Sanguem house facilities that handle hazardous and volatile reactions. In these environments, RTD PT-100 sensors act as the primary safety barrier. Exothermic reactions require precise thermal management to prevent thermal runaway scenarios which could lead to explosions or toxic leaks. Unlike thermocouples, RTDs offer the high stability and linearity needed for these narrow-range, high-precision control loops. We support these industries by ensuring their sensors meet the intrinsic safety and accuracy requirements necessary for hazardous area operations. Our calibration reports help plant managers demonstrate to safety auditors that their emergency shutdown systems and process controls are functioning based on accurate thermal data, thereby protecting both personnel and plant assets.The chemical manufacturing plants in the Pashamylaram industrial area deal with highly exothermic reactions where temperature monitoring is a matter of life and safety. RTD PT-100 sensors are the preferred choice here due to their linear response and high accuracy in corrosive environments. Vega provides specialized calibration for flameproof and explosion-proof RTD assemblies, ensuring that the temperature data fed into the Plant Control System (PCS) or PLC is 100% accurate. Our calibration process includes checking the insulation resistance of the probes, which is critical in chemical plants to prevent electrical interference from skewing temperature readings. By providing NABL-certified calibration for reactors and storage tanks, Vega helps chemical companies maintain safe operating envelopes and comply with stringent environmental and safety regulations, preventing catastrophic thermal runaways.

Industrial Use Cases

Cold Chain and Vaccine Storage

For logistics providers near the Rajiv Gandhi International Airport (Shamshabad), maintaining a strict cold chain for vaccines and biologicals is a primary use case for RTD PT-100 sensors. These sensors are integrated into ultra-low temperature (ULT) freezers and refrigerated trucks that must stay at -70°C or 2-8°C respectively. Vega’s calibration ensures that the data loggers and sensors accurately reflect the internal environment, providing a documented trail for every minute of storage. If a sensor drifts, it could lead to the silent spoilage of temperature-sensitive vaccines. Our NABL-accredited calibration gives logistics companies the confidence that their sensors are accurate to within ±0.1°C, which is a mandatory requirement for WHO and GxP compliance. We help secure the global supply chain by validating the sensors that monitor the journey of medicines from Hyderabad to the world.

Autoclave and Sterilization Validation

In hospitals and diagnostic labs across Mehdipatnam and Madhapur, RTD PT-100 sensors are used to validate sterilization cycles in autoclaves. For a successful sterilization, the equipment must maintain 121°C at a specific pressure for a set time. Vega’s role is to calibrate the RTDs to ensure they are accurately triggering the timer only when the target temperature is reached at the coldest spot of the chamber. A sensor that reads higher than the actual temperature could lead to incomplete sterilization, posing a significant risk of infection. We perform multi-point calibration across the sterilization range to verify that the sensors respond quickly to temperature changes. This use case is vital for the medical industry to meet NABH accreditation standards and ensures that surgical instruments and laboratory media are truly sterile before use.

Industrial Oven and Furnace Mapping

In the manufacturing units of Kukatpally and Balanagar, RTD sensors are used to monitor the temperature uniformity of industrial ovens. For processes like powder coating or curing of composites, the temperature must be uniform across the entire volume of the oven. Vega uses master RTD sensors to perform 9-point or 27-point thermal mapping, comparing the oven's internal temperature distribution against the setpoint on the controller. This use case identifies "cold spots" that could lead to uneven curing or product failure. Our calibration services ensure that the RTDs controlling the heating elements are perfectly calibrated, reducing scrap rates and improving energy efficiency. By ensuring the thermal uniformity of your equipment, Vega helps you deliver high-quality finished goods that meet the stringent specifications of the aerospace and defense sectors.

HVAC and Cleanroom Monitoring

The high-tech cleanrooms in Gachibowli and Hi-Tech City require precise temperature and humidity control to protect sensitive electronic components and pharmaceutical products. RTD PT-100 sensors are integrated into the Building Management System (BMS) to regulate the Air Handling Units (AHUs). Vega calibrates these sensors to ensure they provide a stable and accurate signal, preventing the HVAC system from overworking or allowing temperature fluctuations that could lead to condensation or static buildup. In cleanroom environments, a deviation of just 2°C can affect the precision of lithography or the stability of a chemical formulation. Vega’s NABL-accredited calibration ensures that your cleanroom environment remains within the specified Class 100 or Class 10,000 limits, supporting the continuous operation of Hyderabad’s thriving semiconductor and biotech industries.
