Choosing the Right Sensor for Oil and Gas: 8 Key Considerations

1. Understanding the Measurement Environment

In the oil and gas sector, temperature sensors often operate in extreme conditions, including high pressures, corrosive substances, and potential exposure to flammable materials. Selecting sensors that can withstand these harsh environments is crucial. Look for sensors with rugged housing and suitable environmental ratings to ensure longevity and reliability.

2. Choosing the Right Sensor for the Material

Different materials require specific sensor types. For instance, pyrometers measure the thermal radiation emitted by surfaces to provide accurate temperature readings without direct contact. When measuring metal surfaces or liquids, consider the emissivity settings; oil and gas materials often exhibit varying emissivity.

If your application involves measuring the temperature of crude oil or natural gas, ensure the selected sensor can handle the specific characteristics of these substances, including their emissivity and reflective properties.

3. Size and Distance to Measure

The size of the object being measured influences sensor selection. The measuring spot should be smaller than the target area for accurate readings. Infrared sensors come with various optical resolutions, allowing you to select sensors with small measuring spots for large distances, essential for pipeline monitoring and other extensive applications.

4. Consider the Ambient Conditions

Ambient temperatures can significantly affect sensor performance. Ensure your infrared pyrometer can operate effectively in the expected temperature range. Some sensors can be equipped with cooling systems to maintain operational limits. Additionally, thermal shock can impact smaller sensors, so consider models with adequate thermal mass or protective measures.

5. Lens Contamination from Dust and Moisture

The presence of dust, debris, or moisture can obscure the sensor lens, leading to inaccurate readings. In oil and gas environments, where dust and vapour can accumulate, it is beneficial to use sensors with protective measures, such as air purge collars, to keep the lens clean. This is particularly important in outdoor or offshore applications.

6. Aiming Accuracy

Accurate aiming is essential for reliable temperature measurements. For larger components, aiming may be straightforward, but in complex setups, such as piping systems, precise alignment is critical. Consider using sensors with laser aiming systems to ensure proper targeting, or models equipped with video aiming for enhanced precision.

7. Integration with Existing Systems

Ensure that the sensor you choose can easily integrate with your existing measurement and control systems. Look for standard output signals, such as mA or voltage signals.

In some cases, Optris sensors are able to provide a thermocouple output so if you replace an existing thermocouple sensor, simply wire up your new IR sensor and no other configuration is required.

Many Optris sensors have the capability to fit an interface card which upgrades the capabilities of the sensor. This can be USB or Ethernet for communication with a PC, or ProfiBus or CANBus for industrial communication.

8. Response Speed for Real-Time Monitoring

In the fast-paced oil and gas industry, quick response times can be crucial. Infrared sensors generally offer faster response times than contact-based sensors, with options available that respond in milliseconds. For processes that require immediate temperature feedback, select sensors known for their rapid response capabilities.
