    • Application Case Study: Pressure/Vacuum Protection in H2S Analyzers

    In the industrial automation space, even the most seasoned manufacturers turn to trusted partners for innovative solutions. That spirit of collaboration led one of Whitman Controls’ peers in the instrumentation space to seek our expertise for a high-stakes application in the Oil & Gas industry. The challenge? Enhance safety and performance in hydrogen sulfide (H₂S) gas analyzers—without compromising cost or reliability. Together, we defined and delivered a simple yet powerful solution that’s now driving better safety outcomes and higher customer confidence across our client’s analyzer lineup. This case study explores how Whitman’s pressure sensing technology helped transform a common industry need into a value-added standard.

    Application Case Study: Vacuum Limit Controls in Digital Screen Printing

    When a leading manufacturer of advanced screen printing equipment faced persistent print quality issues tied to vacuum instability, they turned to Whitman Controls for a solution. The challenge centered on maintaining tightly controlled vacuum levels within CTS printers to prevent ink head failures—either from air gaps or unwanted ink weeping. Whitman’s answer was a simple yet robust solution: dual discrete vacuum switches with adjustable setpoints and alarm integration, using the ultra-reliable P117V Stainless Steel Vacuum Switch. The result? A 100% reduction in ink head issues and a 7% boost in productivity. This collaboration highlights how thoughtful instrumentation can bring precision and consistency to even the most artistic industrial processes.

    Application Case Study: Level Control in Hydraulic Power Units

    Most of us working in industrial fields are endlessly impressed by large scale fluid applications, especially those that seem too complex or massive to comprehend. Intercontinental pipelines, hydroelectric dams, and municipal water treatment plants are just a few examples that come to mind. As impressive as these monstrous systems can be, there’s ample reason to be equally inspired by applications on the opposite end of the spectrum, where miniscule amounts of fluids can be pumped accurately down to a fraction of a raindrop in volume.

    Application Case Study: Pressure Protection in Vehicle Hydraulic Testing

    Most readers will have a mental concept of surface mining, with big excavators and dump trucks zipping about a pit dug into the Earth in search of valuable materials such as copper, gold, and diamonds. We thought we had a good understanding of what open-pit mining entailed as well, until we learned just how big the equipment used in these operations really is. Not long back, we received an inquiry from a returning client looking to address an automation challenge with their hydraulic test rigs – rigs that exclusively tested mining equipment hydraulics used in large open-pit mines. As the client described their test rigs and the mining vehicles they served, we realized that our mental image of mining equipment was way too small. Luckily, even such large equipment and the test rigs that keep them in tip-top operation still use normal sized instrumentation. With that, we turned our attention to the client’s concerns about protecting their test rigs from significant, hazardous high pressure situations, and dug right in.

    Application Case Study: Pressure Control in Adiabatic Cooling

    A prospective client requested Whitman’s review of a new application they were working on involving industrial adiabatic cooling technology, seeking an analysis and recommendation on control sensor solutions that could fit into a new product lineup they were developing. “Sure, we’ll help,” we said, “that sounds pretty cool.” Pun completely intended!

    Application Case Study: Pressure Protection in CO2 Lasers

    Tuesday mornings are arguably the best possible time of the week to be reminded of high school science terms we haven’t thought about for too many decades. Or at least for one Tuesday morning in particular, in which we received an email asking about our experience in gas control for interferometry propagation. We’ll save you a Wikipedia search – lasers; they were referring to lasers. This email was from a leading CO2 fabrication laser manufacturer looking for assistance in solving a gas mixture delivery challenge for an upcoming continuous laser marking application.
