Industry Segments We Serve

Pharmaceutical & Biotechnology Industry

The pharmaceutical sector is the largest consumer of high-precision RTD PT-100 calibration services due to the direct impact of temperature on drug efficacy and patient safety. In manufacturing hubs like Navi Mumbai and Patalganga, where Active Pharmaceutical Ingredients (APIs) and formulations are produced, the temperature control of bioreactors and stability chambers is non-negotiable. An error of even 0.5°C can lead to failed batches, compromised sterility, or degraded chemical compounds. Consequently, Quality Assurance departments in these industries demand calibration certificates that strictly adhere to ISO/IEC 17025:2017 standards to withstand rigorous audits from bodies like the USFDA and CDSCO. Vega supports these clients by ensuring their thermal sensors—used in everything from raw material storage to final product lyophilization—maintain traceability to national standards, safeguarding their brand reputation and compliance status.

Food & Beverage Processing

For the Food & Beverage industry, particularly in regions like Taloja and Khopoli, RTD PT-100 calibration is the line of defense against microbial growth and spoilage. This segment relies heavily on thermal processing steps such as pasteurization, sterilization (UHT), and deep-freezing. If a temperature controller reads 72°C during pasteurization when the actual temperature is only 68°C, harmful pathogens like Salmonella or Listeria may survive, leading to catastrophic public health outbreaks and product recalls. Conversely, overheating can destroy the nutritional value and taste profile of the product. Our calibration services ensure that food processors comply with HACCP (Hazard Analysis Critical Control Point) and FSSAI regulations. We verify the accuracy of sensors used in dairy silos, beverage bottling lines, and industrial ovens, ensuring that the critical control points (CCPs) are monitored accurately to maintain shelf-life and consumer trust.

Automotive & Paint Industry

The automotive sector, with its sprawling supply chains in Pune, Chakan, and Panvel, utilizes RTD PT-100 sensors for critical quality applications, most notably in paint curing ovens and engine testing beds. In the paint shop, the curing of primer and clear coats requires a precise temperature profile; if the oven is too cool, the paint won't bond, leading to peeling; if too hot, it becomes brittle or discolored. Beyond aesthetics, thermal calibration is vital for engine and component testing where thermal shock and endurance tests simulate real-world conditions. A sensor drift in a climatic chamber could invalidate weeks of testing data. Vega’s calibration services help automotive OEMs and Tier-1 suppliers maintain the rigorous standards of IATF 16949 by ensuring that the thermal cycles defined in their engineering specifications are replicated exactly in the physical manufacturing process.

Chemical & Petrochemical Processing

In the volatile environments of chemical plants found in Turbhe, Thane, and Raigad, temperature control is often a matter of safety rather than just quality. Chemical reactions, especially exothermic ones, require precise thermal regulation to prevent runaway reactions that could lead to explosions or hazardous leaks. RTD PT-100 sensors are the eyes of the Distributed Control System (DCS), feeding real-time data to operators. If these sensors drift, the efficiency of the reaction drops, affecting yield and byproduct formation. More critically, a false low reading could mask a dangerous temperature spike. Vega provides robust on-site calibration services for these hazardous zones, ensuring that sensors—often housed in explosion-proof thermowells—are verified against reference standards without compromising plant safety protocols, satisfying the stringent requirements of process safety audits.

Industrial Use Cases

Autoclave Sterilization Validation

In the pharmaceutical and healthcare industries, the autoclave is the workhorse of sterility. It uses high-pressure saturated steam at 121°C to kill microorganisms. The RTD PT-100 sensor inside the autoclave controls the cycle. If this sensor drifts by even a small margin, the load may not reach the required "kill time" (F0 value), resulting in non-sterile surgical instruments or contaminated vials. We see this use case frequently in hospitals and pharma units in Nerul and Belapur. The use case involves not just calibrating the controller sensor but also performing heat distribution studies using multiple sensors to ensure the "coldest spot" in the chamber reaches sterilization temperature. Vega’s calibration ensures that the validation logic holds true, preventing the release of non-sterile batches.

Environmental Test Chambers (Climatic Chambers)

Electronics and material testing labs in Airoli and Mahape use climatic chambers to test how products withstand extreme heat and cold. These chambers rely on PT-100 sensors to cycle temperatures rapidly between -40°C and +85°C. A specific use case involves the "thermal shock" testing of automotive PCBs. If the chamber's sensor is sluggish or inaccurate, the thermal stress applied to the product will be incorrect, leading to a product passing the test in the lab but failing in the field. Our service involves calibrating the chamber controller and performing a spatial mapping of the chamber volume to ensure that a product placed on the top shelf experiences the same temperature as one on the bottom shelf, ensuring test repeatability.

Clean-in-Place (CIP) Systems

In the dairy and beverage industries located near Khanda Colony and Old Panvel, piping systems are cleaned automatically using CIP processes. This involves circulating hot caustic and acid solutions at specific temperatures (e.g., 80°C) to sanitize pipes without dismantling them. The RTD sensor controls the temperature of the cleaning fluid. If the temperature is too low, the cleaning is ineffective, leading to bacterial buildup (biofilm). If it is too high, it wastes energy and can damage gaskets. Vega’s calibration of these sensors ensures that the CIP process is validated, guaranteeing that every cleaning cycle meets the hygiene standards required for food safety audits like FSSC 22000.

Heat Treatment & Annealing Furnaces

Metalworking units in industrial estates like MIDC Taloja utilize large furnaces for annealing steel components to relieve internal stresses. These furnaces operate at high temperatures (often utilizing high-temp RTDs or thermocouples, but precision stages use RTDs). A critical use case is the "soak time" where the metal must be held at a precise temperature for a set duration. If the control sensor reads higher than the actual temperature, the metal is under-processed and may crack during machining. Vega provides system accuracy tests (SAT) and temperature uniformity surveys (TUS) to ensure that the furnace controller, the recording chart, and the actual zone temperature are all aligned, adhering to metallurgical standards like AMS 2750.

Compliance & Audit Requirements

For industries calibration is not just about accuracy; it is about traceability and compliance.

• ISO/IEC 17025:2017: The gold standard for competence of testing and calibration laboratories. Our reports include measurement uncertainty, traceability to SI units, and decision rules, ensuring acceptance globally.

• FDA 21 CFR Part 11 & Part 211: For our pharma clients, we ensure that calibration records are attributable, legible, contemporaneous, original, and accurate (ALCOA+). Our digital certificates support your electronic record compliance.

• GMP / GLP: Good Manufacturing and Laboratory Practices mandate that all "critical" instruments must be calibrated at defined intervals. We help you define these intervals based on risk assessment and historical drift data.

• HACCP (Food Safety): Critical Control Points (CCPs) involving temperature must be verified. Our calibration stickers and certificates serve as the physical proof required during food safety audits.

Frequently Asked Questions (FAQs)

Q: What is the difference between a standard calibration and an NABL accredited calibration?

A: A standard calibration may just check accuracy, but an NABL accredited calibration (ISO 17025) guarantees that the lab has been audited by the National Accreditation Board for Testing and Calibration Laboratories. It ensures the results are traceable to national standards and the uncertainty of measurement is calculated. For audits in Pharma and regulated sectors, NABL reports are mandatory.

Q: How often should I calibrate my RTD PT-100 sensors?

A: The frequency depends on the criticality of your process and the harshness of the environment. Typically, industries in Panvel and Mumbai schedule calibration every 6 to 12 months. However, for critical pharma applications, it might be quarterly or before every major validation cycle.

Q: Can you calibrate sensors without removing them from the machine?

A: Yes, we offer onsite calibration services. We bring portable dry block calibrators and reference standards to your facility in locations like Taloja or Bhiwandi. However, for the highest accuracy, lab calibration is recommended.

Q: What is the valid range for PT-100 calibration?

A: A: While a PT-100 can theoretically measure from -200°C to +850°C, most industrial calibrations cover the operating range of the specific process, commonly -30°C to 250°C. We can customize the calibration points based on your usage.
