The AM1612 full immersion PRT is uniquely designed to provide users with an excellent temperature probe that can expose the transition joint and connecting wires to an environment covering the full PRT temperature range. The probe's seal prevents moisture ingress, allowing it to operate in humid conditions or even when fully immersed in common heat transfer fluids such as ethanol, silicone oil and mineral oil. It has wide application in freezers, temperature/humidity chambers and sterilisers.
The AM1612 is small in size with a probe length of 50 mm and a diameter of 3 mm. A unique assembly procedure ensures the best balance of hysteresis, mechanical shock and thermal shock performance. Each probe comes with a NIST-referenced calibration certificate as standard.
What is a full immersion PRT?
A “full immersion” Platinum Resistance Thermometer (PRT) is a specific type of temperature sensor designed for applications that require the sensitive part of the thermometer to be fully immersed in a medium (such as a liquid or gas) to obtain an accurate measurement. This feature is crucial in many scientific and industrial applications where precise temperature measurements are required.
The core function of a full immersion PRT is based on the resistance change of platinum with temperature changes. The sensor contains a platinum wire or film, whose electrical resistance varies with temperature. This change in resistance is measured and converted into a temperature value. The accuracy and reliability of a PRT make it an ideal choice for accurate temperature measurements.
The unique feature of full immersion PRTs is their design, which allows them to be fully immersed in the medium to be measured. This ensures a more uniform and representative measurement of temperature over the entire measurement area. They are particularly useful in applications where temperature gradients or stratification may occur in the medium, such as in large storage tanks, environmental observations or in processes involving liquids.
These thermometers are often manufactured with materials resistant to corrosion and other harmful effects of the environment in which they are used. They are available in different sizes and configurations, depending on the specific requirements of the application, such as the required insertion depth, sensitivity, and durability.
Full immersion PRTs are widely used in industries such as chemical processing, pharmaceuticals, food production, and environmental sciences, where accurate and reliable temperature measurements are crucial for process control, quality assurance and research.
