Industry Segments We Serve

Oil & Gas Refining

In large-scale oil and gas refineries such as those operated by Aramco, RTD PT-100 sensors play a mission-critical role in monitoring temperatures across fractional distillation columns, crude heaters, heat exchangers, and catalytic reactors. These processes depend on extremely tight temperature control to separate hydrocarbons into precise fractions such as LPG, naphtha, kerosene, and diesel. Even a minor drift of 0.5–1°C in a PT-100 sensor can shift the boiling point profile, leading to off-spec products, reduced yield, or increased reprocessing costs. More critically, inaccurate temperature data can mask unsafe operating conditions, causing excessive pressure buildup or catalyst degradation. Calibration of RTD PT-100 sensors in refining environments must account for high temperatures, vibration, and corrosive atmospheres. Our NABL/ISO-compliant calibration methodology ensures these sensors maintain accuracy, stability, and traceability, directly supporting process safety, energy efficiency, and refinery compliance with international standards.

Desalination Plants

Saudi Arabia’s desalination infrastructure, including major facilities in Shoaiba and Ras Al-Khair, relies heavily on RTD PT-100 sensors to control and monitor seawater heating, brine temperatures, and steam generation in multi-stage flash (MSF), multi-effect distillation (MED), and reverse osmosis (RO) pretreatment systems. These environments are exceptionally harsh, characterized by high salinity, scaling, humidity, and continuous thermal cycling. Over time, PT-100 sensors exposed to saline corrosion and mineral deposition can drift, resulting in inefficient heat transfer, excessive energy consumption, or accelerated equipment fouling. Accurate temperature measurement is essential to maintain optimal evaporation rates and protect critical assets such as heat exchangers and evaporators. Our calibration services ensure PT-100 sensors remain accurate and stable despite these conditions, verifying performance against traceable standards and supporting reliable, energy-efficient freshwater production in compliance with regional operational and environmental requirements.

Pharmaceutical Stability

With the rapid expansion of biopharmaceutical manufacturing and research facilities in Riyadh, RTD PT-100 sensors are essential for monitoring stability chambers, cold rooms, and ultra-low temperature freezers operating at -20°C, -40°C, and -80°C. These environments are used to store vaccines, biologics, cell therapies, and other temperature-sensitive medicines where even minor temperature excursions can compromise product efficacy or invalidate stability studies. Regulatory bodies such as the Saudi Food and Drug Authority (SFDA) require documented evidence that temperature monitoring systems are accurate, traceable, and regularly calibrated. Our calibration services provide complete “As-Found” and “As-Left” data, uncertainty analysis, and traceability documentation aligned with ISO/IEC 17025 principles. This ensures pharmaceutical manufacturers can confidently demonstrate data integrity, maintain compliance, and protect high-value medicinal products throughout their lifecycle.

Solar Thermal Power

In Saudi Arabia’s growing renewable energy sector, particularly in concentrated solar power (CSP) plants, RTD PT-100 sensors are used to monitor the temperature of heat transfer fluids such as molten salts and synthetic oils. These systems operate under extreme desert conditions, experiencing intense solar heating during the day and rapid cooling at night. Such aggressive thermal cycling places significant stress on temperature sensors, leading to potential drift, loss of accuracy, or mechanical fatigue over time. Precise temperature measurement is vital for maintaining thermal efficiency, protecting storage systems, and optimizing energy dispatch to the grid. Our calibration services ensure that PT-100 sensors used in CSP plants maintain accuracy across wide temperature ranges and prolonged operating cycles. By validating sensor performance against traceable standards, we support the long-term reliability and efficiency of solar thermal assets critical to the Kingdom’s energy diversification goals.

Industrial Use Cases

Petrochemicals & Chemicals

In the industrial cities of Jubail and Yanbu, precision is a matter of safety. We calibrate the RTD PT-100 sensors that control exothermic reactions in polyethylene and polypropylene plants. Our NABL reports help these facilities maintain compliance with SABIC internal quality standards and global safety audits.

Food, Beverage & Dairy

The Kingdom's dairy giants, such as Almarai in Al Kharj, rely on thousands of RTD PT-100 sensors for pasteurization and flash-freezing. Our calibration services ensure that the temperature-time relationship required to kill pathogens is strictly maintained, satisfying SASO and HACCP requirements.

Power Generation & Utilities

From the gas-fired power plants in Ghazlan to the new green hydrogen projects in NEOM, PT-100 sensors are the primary method for monitoring turbine exhaust and cooling water. Vega provides the high-temperature calibration needed to ensure these plants operate at peak thermodynamic efficiency.

Heat Treatment & Annealing Furnaces

Metalworking units in industrial estates 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.

Frequently Asked Questions (FAQs)

Q: Why is a 4-wire RTD PT-100 preferred for refineries in Jubail over a 3-wire?

A:In large refineries, the distance between the sensor and the control room can be hundreds of meters. A 4-wire configuration completely cancels out the lead-wire resistance, which can fluctuate with the extreme Saudi heat. Our calibration verifies that this accuracy is maintained across the entire loop.

Q: How does the Saudi climate affect the calibration interval of an RTD?

A: Extreme heat and sand ingress can cause physical degradation of the sensor sheath, leading to faster drift. While the standard is 12 months, for critical desert operations, we recommend a 6-month recalibration cycle to ensure "Technical Soundness."

Q: Can Vega provide calibration certificates that satisfy the Saudi Food and Drug Authority (SFDA)?

A: Yes. Our NABL-accredited certificates are internationally recognized through the ILAC MRA, making them fully compliant with SFDA requirements for pharmaceutical and food industries.

Q: What is the significance of the "Uncertainty of Measurement" (MU) in our Dammam plant's audit?

A: MU provides a statistical range of the "true" temperature. In high-precision sectors like Aerospace or Petrochemicals, auditors require this to ensure that your process tolerance (e.g., ±1°C) is not "eaten up" by the laboratory's own measurement error.
