FAQ

Have a Question?

Check out our FAQ below or fill out our contact form for more information.
Can Thermometer Wells improve safety in tank car operations?

Absolutely. By isolating the temperature sensor from the process fluid, Thermometer Wells reduce the risk of leaks and contamination. This feature ensures safer handling of hazardous materials, a key concern for tank car applications.

Are Thermometer Wells suitable for high-vibration environments?

Yes, Thermometer Wells can be designed to withstand high-vibration environments. Reinforced designs and materials help minimize the risk of sensor damage or measurement inaccuracies, making them ideal for applications like rail tank cars.

Are McKenzie Valve’s Thermometer Wells compliant with industry standards?

Yes, our Thermometer Wells are AAR Approved, meeting the stringent standards set by the Association of American Railroads for safety and reliability in tank car applications.

What materials are McKenzie Valve’s Thermometer Wells made from?

Our Thermometer Wells are available in carbon steel and stainless steel options. These materials are chosen for their durability and compatibility with various industrial applications, ensuring reliable performance in demanding environments.

What is a Thermometer Well, and why is it important in tank car applications?

A Thermometer Well, also known as a thermowell, is a protective fitting installed in tanks or pipelines to house temperature sensors like thermometers or thermocouples. In tank car applications, it allows for accurate temperature measurement of the contents without direct exposure to the process fluid, ensuring sensor longevity and maintaining system integrity.
