The Johnson AD-1272 Thermal Dispersion Airflow Temperature Measuring Probe is an advanced industrial temperature sensing device engineered for precise and reliable measurements in high-airflow environments. Its innovative design combines the principles of thermal dispersion and airflow sensing, making it an ideal choice for processes that require both temperature and velocity information.
Through the application of thermal dispersion technology, this probe is capable of accurately measuring temperature in the presence of flowing air or gas streams without the need for a separate temperature element. The probe features a rugged, 316L stainless steel construction, ensuring superior durability and longevity in even the most demanding industrial settings.
Equipped with a 4:1 airflow to temperature ratio, the AD-1272 probe offers excellent process control and monitoring capabilities. It is suitable for low to high airflow applications with temperatures ranging from -20 C to 200 C (-4 F to 392 F). The probe provides a 0.1 C or 0.1% of reading accuracy, making it an essential tool for maintaining optimal process conditions and preventing equipment failures.
To achieve optimal performance, the Johnson AD-1272 probe comes with a detachable, interchangeable 4-wire RTD temperature sensor (Pt100) that is independently compensated for temperature and humidity. The probe is also fully calibrated in both airflow and temperature at the time of manufacture, ensuring 3% typical airflow accuracy and repeatability.
The probe features a compact probe tip design, which minimizes the dead air volume and allows for easy integration with various industrial process control systems. It boasts a quick-connect electrical termination, offering flexibility and ease of installation. A protective borosilicate glass bead thermowell shields the sensor from potential damage during installation or operation.
Engineered for industrial applications, the Johnson AD-1272 Airflow Temperature Measuring Probe offers superior accuracy, reliability, and flexibility. It's the perfect solution for industrial processes requiring concurrent temperature and airflow measurements, such as boiler auxiliary systems, combustion control, and HVAC, among many others.
The Johnson Yokogawa AD-1272 is a thermal dispersion infrared (TDI) airflow temperature measuring probe, which is designed to provide non-contact temperature readings in gas and liquid flows. Here are some pros and cons of buying a Johnson AD-1272 probe:
Pros:1. Non-contact measurement: The AD-1272 probe provides non-contact temperature readings, making it ideal for measuring temperatures in harsh environments where direct contact with sensors is not possible.
2. High accuracy: The TDI technology used in the AD-1272 probe offers high accuracy, making it suitable for applications that require precise temperature measurement.
3. Robust design: The probe is designed to withstand harsh process conditions, making it suitable for use in industries such as oil and gas, chemical, power, and pharmaceuticals.
4. Easy to install: The probe can be installed easily and quickly, making it an ideal solution for applications where downtime is minimized.
5. Wide temperature range: The AD-1272 probe can measure temperatures ranging from -40 C to 650 C, making it suitable for a wide range of process applications.
Cons:1. Cost: The AD-1272 probe is a high-performance temperature measuring probe, which comes with a higher price tag compared to less advanced solutions.
2. Requires calibration: The TDI technology used in the AD-1272 probe requires regular calibration to ensure accurate temperature measurements. This can add to the operational costs.
3. Limited measurement range: The probe can only measure temperatures up to 650 C, making it not suitable for applications that require higher temperature measurement ranges.
4. Limited process gases: The probe is not suitable for use in applications where the process gas is not compatible with the TDI sensing element.
Conclusion:The Johnson AD-1272 thermal dispersion infrared airflow temperature measuring probe is a high-performance tool for non-contact temperature measurement in harsh environments. With its wide temperature range, high accuracy, and robust design, it is an ideal choice for industries such as oil and gas, chemical, power, and pharmaceuticals. However, it comes with a higher price tag compared to less advanced solutions and requires regular calibration to ensure accurate temperature measurements.
Recommendation:If you are looking for a high-performance, non-contact temperature measuring probe for harsh environments, the Johnson AD-1272 is an excellent choice. However, it is important to consider the costs associated with calibration and ensure that the process gas is compatible with the TDI sensing element before making a purchase. If cost is a concern or if the temperature measurement range is outside the capability of the AD-1272, there are other temperature measurement solutions available on the market that may better suit your needs. It's always a good idea to consult with an experienced temperature measurement specialist to help you assess your specific requirements and choose the best solution for your application.
This is new unused. Nothing in the board is clean as new. No box its been sitting on the shelf so theres a little bit of dust etc. Comes as pictured.
