The Operation of Gages and Switches in Hazardous Environments

In many industrial processes, the materials and the end product or by-products of the process, such as dust or vapors, can create conditions for a hazardous environment. Processes that have potential for hazardous environments include: water treatment, oil drilling, gas and chemical processing, power generation, pharmaceutical, and food manufacturing. The measurement and control of these processes are essential in maintaining optimal conditions of the manufacturing system and preventing catastrophic events.  Continue reading “The Operation of Gages and Switches in Hazardous Environments”

The Making of a Market Leader – The Magnehelic® Differential Pressure Gage

The name of the Magnehelic® Differential Pressure Gage was derived from the terms Magnet and the Helix. The Magnehelic® gage is a simple yet elegant solution, which solved a problem faced by customers who wanted to measure low differential pressure. Historically the industry measured differential

pressure with a liquid filled manometer. The manometer worked on the principle that the difference in air pressure is measured as a function of gravity and liquid density. The challenge, however, was that the liquid in the manometer evaporates over time. This means that individuals would need to regularly add more liquid and re-calibrate the device.
