Choosing the right differential pressure monitoring system can show your employees that your care about their safety.

What’s that smell? From procedures as complicated as those involved in electrolysis to more commonly understood tasks like coffee roasting, many industrial processes create byproducts that we do not necessarily want escaping into the air we all breathe.

Sure, roasting coffee has an enticing aroma—especially when you’re waking up in the morning—but most other manufacturing processes involving chemical, physical, electrical or mechanical changes do not emit such pleasant odors. And worse yet, many of these processes result in pollutants much more harmful than a whiff of espresso.

Consider coffee roasting as an example. When roasting coffee, chaff—the papery-thin skin of the coffee bean—falls off. In industrial roasting plants, special filters collect chaff and other pollutants, helping ensure they do not penetrate the air outside the facility. Consequently, these filters must be cleaned periodically for maximum efficiency. But what if the filter had a hole or tear, allowing chaff and other pollutants to escape?

Enter differential air pressure monitoring. Ideal for monitoring HVAC filters, exhaust blowers and clean rooms, differential pressure sensors help ensure optimal indoor conditions, improve energy efficiency and protect human health and well-being. Throughout the rest of this article, we’ll delve into what differential air pressure is and why it’s important, highlighting critical applications for differential air pressure sensors.

What is Differential Air Pressure?

Air pressure is the weight of air molecules, with cool molecules being heavier and denser than warm air molecules. But measuring how the air presses down onto the earth or other objects can be incredibly difficult. Consider checking the air pressure of your car’s tires. A tire gauge will inform you that the pressure is a certain number of pounds per square inch, but what does that mean? Basic air pressure measures the difference between the atmospheric pressure outside the tire and the air pressure inside the tire.

Empower your workforce with the manufacturing, industrial maintenance, operations, HSE, compliance, and professional development skills they need to complete their tasks efficiently and safely. Not only will you boost productivity, reliability, skills, and morale but you’ll also onboard faster, and retain your best employees while meeting regulatory standards. Vector Solutions offers over 1,800 award-winning eLearning courses designed to keep your employees safe, transfer knowledge of fundamentals, and develop industry and job-specific skills that reduce downtime, maintenance costs and more.

EHS professionals have been tackling the subject of how to best measure performance for many years. Lagging indicators like the Total Recordable Incident Rate (TRIR) and Days Away Restricted Transfer Rate (DART) are a good place to start, but you shouldn’t forget about the leading indicators that your workforce does every day to prevent incidents from occurring. Learn about some of the most common KPIs of safety programs and how Vector EHS Management software can be used to track these metrics in this webinar.

In case you missed it, OSHA recently initiated an enforcement program to identify employers who fail to electronically submit Form 300A recordkeeping data to the agency. When it comes to OSHA recordkeeping, there are always questions regarding the requirements and ins and outs. This guide is here to help! We’ll explain reporting, recording, and online reporting requirements in detail.
