Comprehensive Service Offerings

Our calibration lab is equipped with high-stability dry blocks, oil baths, and multifunction calibrators to provide highly accurate results. We offer:

• On-Site Calibration: Direct calibration at your facility to minimize downtime.

• In-Lab Calibration: Controlled environment testing for high-precision master sensors.

• Fixed Point & Comparison Methods: Utilizing the International Temperature Scale of 1990 (ITS-90) standards.

• Multi-Point Validation: Testing across your specific operational range (e.g., -80°C to 600°C) to ensure linearity and accuracy.

• Comparison Calibration (Liquid Bath Method): This is the most common method for high-accuracy industrial PT-100 sensors. The Unit Under Calibration (UUC) is immersed in a highly stable stirred liquid bath alongside a Standard Platinum Resistance Thermometer (SPRT). This method ensures excellent thermal homogeneity and stability, suitable for high-precision sensors used in pharma and labs.

• Dry Block Comparison Calibration: Ideal for on-site services at locations like Anand or Gandhinagar, where liquid baths are impractical. We use portable, high-stability dry block calibrators to generate specific temperature points. This method allows us to calibrate sensors without removing them entirely from the process environment if necessary, minimizing downtime.

• Fixed Point Calibration (Primary Standards): While primarily used for reference standards, this involves calibrating at intrinsic physical fixed points (like the Triple Point of Water) for the highest possible accuracy, typically reserved for reference class PT-100 sensors used by other calibration labs.

• Loop Calibration (System Calibration): This involves calibrating the PT-100 sensor and the temperature controller/display unit together as a single system. This is crucial for verifying the actual temperature reading displayed to the operator, ensuring the specific error of the display is accounted for alongside the sensor drift.

Industry Segments We Serve

Pharmaceutical & Biotechnology Sector

The pharmaceutical industry is the heartbeat of Gujarat's industrial landscape, particularly in areas like Sarkhej and Changodar. For this sector, RTD PT-100 calibration is not optional; it is a critical regulatory mandate. In drug manufacturing, temperature control determines the efficacy and safety of the final product. Even a deviation of 0.5°C in a bioreactor or an autoclave can result in a failed batch, costing millions. Our services cater to this segment by ensuring that every sensor used in critical process parameters (CPP) is calibrated with traceability to national standards. We understand the high stakes involved in audit trails, which is why our calibration certificates for pharma clients are designed to be comprehensive, including "As Found" and "As Left" data, ensuring full compliance with 21 CFR Part 11 and global GMP standards. We support the rigorous demands of quality assurance departments that require low uncertainty budgets to maintain their process capability indices (Cpk).

Chemical & Petrochemical Processing

The chemical manufacturing belt, spanning from Naroda to Vatva, relies heavily on exothermic and endothermic reaction control. In this industry, RTD PT-100 sensors are the primary eyes of the control system. Accurate calibration is vital for safety and yield optimization. A drifting temperature sensor in a polymerization reactor can lead to runaway reactions or substandard polymer chains. Our services for the chemical sector focus on robustness and range. We calibrate sensors that operate in harsh environments, ensuring that the thermal lag or sensor degradation due to chemical exposure is identified. By providing precise calibration data, we help chemical plant managers optimize their energy consumption—preventing overheating in distillation columns and ensuring that reaction kinetics are maintained exactly as per the chemical engineering design. Our on-site team is trained to work in hazardous zones, adhering to strict safety protocols while delivering metrological accuracy.

Food & Beverage and Dairy Industry

With major dairy and food processing units located near Gandhinagar and Bavla, the food safety aspect of temperature calibration cannot be overstated. The Food Safety and Standards Authority of India (FSSAI) and HACCP guidelines mandate strict temperature monitoring for pasteurization, sterilization, and cold chain storage. An inaccurate PT-100 sensor in a milk pasteurization unit could mean that harmful bacteria are not eliminated, posing a severe public health risk. Conversely, overheating destroys the nutritional value and taste profile of the food. Vega’s calibration services ensure that the "Critical Control Points" (CCPs) in your HACCP plan are monitored accurately. We perform calibration for sensors used in blast freezers, ovens, and reefer vehicles, ensuring that the cold chain remains unbroken and verifiable. Our certificates serve as proof of due diligence during food safety audits, protecting your brand reputation and ensuring consumer safety.

Automotive & Engineering Manufacturing

The automotive hub in Sanand and the engineering workshops in Odhav require precise thermal processing for material properties. Heat treatment processes such as annealing, hardening, and tempering rely entirely on the accuracy of the furnace temperature. If a PT-100 sensor in a heat treatment furnace reads 850°C when the actual temperature is 830°C, the metal components may not achieve the required hardness or tensile strength, leading to mechanical failure in the field. Our calibration services for the automotive sector ensure that furnace controllers and sensors are synchronized and accurate. We assist in Uniformity Surveys (TUS) and System Accuracy Tests (SAT) as per AMS 2750 guidelines where applicable. By maintaining the accuracy of these thermal instruments, we help automotive manufacturers prevent recalls and ensure that every gear, shaft, and chassis component meets the strict metallurgical specifications required by global automotive giants.

Industrial Use Cases

Autoclave & Sterilization Validation (Pharma/Medical)

In pharmaceutical manufacturing facilities in Moraiya and hospitals across Ahmedabad, autoclaves are used to sterilize equipment and products. The critical parameter here is maintaining a specific temperature (usually 121°C) for a set duration to kill microbial life. The PT-100 sensors controlling these autoclaves must be incredibly accurate. A reading that is higher than the actual temperature results in non-sterile loads being released, which is a catastrophic compliance failure. Our use case involves not just calibrating the controller sensor but also performing temperature distribution studies using multiple calibrated sensors. We ensure that the "cold spot" in the autoclave chamber reaches the sterilization temperature. This calibration is vital for the "Validation Master Plan" of any pharma company, ensuring that the F0 value (sterilization lethality) calculated by the system is real and accurate.

Cold Storage & Warehouse Thermal Mapping (Logistics)

For logistics companies operating in Aslali and Sarkhej, maintaining the integrity of temperature-sensitive goods like vaccines, insulin, or perishable foods is a daily challenge. Large warehouses use RTD PT-100 sensors to monitor ambient temperature. If these sensors drift, the warehouse management system (WMS) might fail to trigger cooling systems, leading to spoilage. Our service involves calibrating the fixed sensors and validating them against a 3D thermal map of the warehouse. We identify hot spots and cold spots that the fixed sensors might miss. For example, a sensor near a loading dock might read higher than the rest of the room. By calibrating these sensors, we ensure that the data logs provided to regulatory bodies (like the FDA or local drug controllers) are accurate representations of the storage conditions, preventing costly product recalls.

Reactors and Distillation Columns (Chemicals)

In the chemical estates of Vatva and GIDC Naroda, precise temperature control governs the yield of chemical reactions. Consider a distillation column separating two volatile solvents with close boiling points. The PT-100 sensors at various trays determines the reflux ratio and the purity of the distillate. If the sensor calibration is off by even 1°C, the separation efficiency drops, leading to impure product and wasted energy. Our calibration use case here involves performing loop checks where we simulate the PT-100 resistance into the transmitter and verify the control room reading (DCS/PLC). We then calibrate the sensor element itself in a bath. This "end-to-end" verification ensures that the operator in the control room sees exactly what is happening inside the reactor, allowing for tight process control and maximum chemical yield.

Textile Dyeing and Drying Processes (Textiles)

Ahmedabad is the "Manchester of the East," and the textile mills in Narol and Piplaj rely heavily on thermal processes. In the dyeing process, the temperature of the dye bath determines the rate of dye uptake and color fastness. If the PT-100 sensor controlling the dye bath is inaccurate, it can lead to shade variation between batches. A "Red" dyed at 90°C looks different from a "Red" dyed at 95°C. For textile exporters, this inconsistency leads to rejected shipments. Our use case involves calibrating the sensors used in jet dyeing machines and stenters (drying ovens). By ensuring these sensors are accurate, we help textile manufacturers achieve "Right First Time" (RFT) dyeing, significantly reducing the cost of re-dyeing, water consumption, and chemical wastage, thereby directly impacting the profitability of the mill.
