Industry Segments We Serve

Pharmaceutical & Biotechnology Manufacturing

The pharmaceutical industry is perhaps the most regulated sector regarding thermal management, governed by stringent guidelines such as USFDA 21 CFR and WHO GMP. In this segment, RTD PT-100 sensors are ubiquitous, found in everything from raw material storage to final product lyophilization. The critical nature of this industry demands that every sensor measuring process parameters—such as reaction temperatures in bioreactors or sterilization temperatures in autoclaves—must be calibrated with high precision. A deviation of even 0.5°C can result in a batch failure, leading to massive financial losses and regulatory observations during audits. Companies operating in zones like the RIICO Industrial Area in Bagru or Kukas rely on Vega’s calibration services to maintain the "validated state" of their equipment. We provide the necessary documentation, including traceability to national standards, which is a prerequisite for any regulatory filing or inspection. Our services ensure that the thermal lag and hysteresis of the sensors are quantified, allowing quality assurance teams to trust their Critical Process Parameters (CPPs).

Automotive & Metallurgical Heat Treatment

For the automotive hub centered around Neemrana and Alwar, heat treatment is a core process that defines the mechanical properties of engine components, gears, and chassis parts. Processes such as annealing, hardening, and tempering require precise temperature profiles, often adhering to the AMS 2750 (CQI-9) standards. RTD PT-100 sensors in this sector are subjected to harsh environments and rapid thermal cycling, which can induce significant drift. Calibration here is not just about reading a number; it is about ensuring the structural integrity of the metal. If a sensor reads lower than the actual temperature, parts may be overheated, leading to brittleness; if it reads higher, the parts may remain soft. Vega Calibration services assist these industries by performing System Accuracy Tests (SAT) and Temperature Uniformity Surveys (TUS), ensuring that the furnace controllers receiving data from the PT-100s are acting on accurate information. This directly impacts the safety and durability of the vehicles produced.

Food & Beverage and Cold Chain Logistics

The Food Safety and Standards Authority of India (FSSAI) and global HACCP standards dictate rigorous temperature controls to prevent microbial growth and spoilage. In the dairy and food processing plants scattered across Vishwakarma Industrial Area (VKI) and Ajmer, PT-100 sensors monitor pasteurization units (HTST), fermentation tanks, and deep freezers. The calibration of these sensors is a matter of public health. For instance, in milk pasteurization, the temperature must be held at exactly 71.7°C for 15 seconds; a sensor error here could mean unsafe milk reaching the market. Furthermore, the cold chain logistics sector, which transports perishables from Jaipur to the rest of India, relies on calibrated vehicle sensors. Vega supports this segment by offering timely calibration of reefer truck sensors and cold storage data loggers. We help these businesses minimize product rejection rates and demonstrate a commitment to quality safety consumers can trust, ensuring the farm-to-fork chain remains unbroken and safe.

Chemical & Petrochemical Processing

Chemical plants, such as those found near Kota and select zones in Jaipur, operate hazardous processes that are often exothermic or pressure-sensitive. Here, temperature is not just a quality parameter; it is a safety interlock. An RTD PT-100 sensor failing to detect a temperature spike in a distillation column or a reactor could lead to catastrophic runaway reactions. Therefore, the calibration of these instruments is a safety-critical activity. We understand that these industries often require "Intrinsically Safe" working procedures. Our technicians are trained to work with safety permits, ensuring that calibration does not interfere with the plant's safety instrumented systems (SIS). We verify the linearity of the sensors across wide spans, ensuring that the control room operators in Malviya Nagar based engineering offices or remote plants see the exact reality of the process. Accurate calibration aids in maximizing yield and minimizing energy consumption by allowing the process to run closer to its optimal thermal limits without crossing safety margins.

Industrial Use Cases

Validation of Autoclaves and Sterilizers

In medical and pharmaceutical contexts, the autoclave is the primary defense against contamination. The use case here involves the precise calibration of load probes and chamber probes (PT-100s) that control the sterilization cycle. For a standard cycle of 121°C for 15 minutes, the sensor accuracy is paramount to calculate the F0 value (equivalent sterilization time). If the PT-100 reads 121.5°C when the actual temperature is 120.9°C, the sterilization might be incomplete, leaving biological indicators alive. Vega’s team performs pre-validation calibration and post-validation verification of these sensors. We service hospitals and pharma units in Mansarovar and Jhotwara, ensuring their autoclaves are not just "hot" but "sterile." Our calibration certificates provide the correction factors needed to adjust the autoclave controller, ensuring that the display matches the physical reality of the saturated steam inside the chamber, thereby guaranteeing patient safety and regulatory compliance.

Temperature Mapping of Warehouses and Cold Rooms

Many logistics companies in the Mahindra World City (SEZ) utilize large-scale cold rooms to store vaccines, chemicals, or food. The use case involves deploying calibrated RTD sensors or data loggers to map the three-dimensional thermal profile of the storage area. Before this mapping can occur, the sensors themselves must be calibrated to ensure they are reading correctly. A differential of 1°C between two sensors could be interpreted as a "hot spot" if not properly calibrated, leading to false failures in the mapping report. Vega provides the foundational calibration for these mapping studies. We ensure that all sensors used for the study have a tight uncertainty budget. This allows facility managers to confidently identify areas near doors or HVAC vents that deviate from the acceptance criteria (e.g., 2°C to 8°C), enabling them to re-rack products or adjust air handling units effectively.

Process Control in Industrial Ovens and Curing Furnaces

Manufacturing units in 22 Godam and Bhiwadi use large conveyor ovens for powder coating or component drying. The PT-100 sensors in these ovens control the heating zones. A common use case is the curing of paint or epoxy, which requires a specific temperature window to bond correctly. If the calibration is off, the oven may run too cool, leading to coating failure (peeling), or too hot, leading to discoloration or burning. Our service involves onsite calibration of these zone sensors. We often find that the "process" sensor fixed to the wall reads differently than the air temperature near the product. By calibrating the control loop, we help manufacturers adjust the offsets in their PID controllers. This ensures that the set point (SV) matches the process value (PV) experienced by the product, reducing scrap rates and energy waste significantly.

Environmental Chamber and Incubator Stability Testing

R&D centers and testing labs in Sitapura require environmental chambers to test product shelf life under accelerated aging conditions (e.g., 40°C / 75% RH). The PT-100 sensors controlling these chambers must be incredibly stable over long periods. The use case here is "Stability Study Compliance." If a chamber runs for 6 months and the sensor drifts by 1°C, the entire 6-month study might be invalidated by an auditor. Vega offers periodic calibration strategies, often recommending pre-study and post-study calibration to bracket the data. We calibrate these sensors against high-precision reference thermometers to verify that the chamber environment remained within the strict tolerances defined by the ICH guidelines. This service provides the "proof of stability" required for bringing new pharmaceutical or chemical products to market.

Compliance & Audit Requirements

Frequently Asked Questions (FAQs)

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

A: The frequency depends on the criticality of the process and the sensor's usage environment. For critical pharma applications, every 6 months is standard. For general industrial applications, an annual (12-month) cycle is common. However, if the sensor is subject to high vibration or extreme thermal shock, more frequent intervals may be required.

Q: Can you perform calibration at our factory in Sitapura, or do we need to send instruments to your lab?

A: We offer both. For minimal downtime, our Onsite Calibration team can visit your factory in Sitapura, VKI, or anywhere in Jaipur. For higher accuracy requirements (Master Sensors), we recommend sending them to our permanent laboratory.

Q: What is the difference between a Standard Calibration and an Accredited (NABL) Calibration?

A: An NABL accredited calibration certificate is issued under the scope of ISO/IEC 17025:2017 and is internationally recognized (via ILAC). It includes a calculated uncertainty of measurement. Non-accredited calibration may not be accepted during ISO or regulatory audits. Vega always recommends NABL accredited calibration for compliance.

Q: Do you calibrate the display controller along with the sensor?

A: Yes, we highly recommend System Calibration. Calibrating the sensor alone ignores the error introduced by the wire resistance and the controller's input circuitry. Calibrating the whole loop ensures the temperature you see is the temperature you have.
