New At AVS: OptraVac | Highly Accurate Direct Vacuum Gauge

New At AVS: OptraVac | Highly Accurate Direct Vacuum Gauge New At AVS 2015: DIGIVAC—wants your feedback on New Vacuum Technology coming to the market—a prototype is available for viewing and discussion at booth #622, October 18th-23rd, during AVS at the San Jose Convention Center. People working with high vacuum are met with 2 problems: 1. The vacuum region from 1×10-5 to 1×10-7 Torr requires devices that employ indirect measurement technology such as cold and hot cathode gauges with typical accuracies of +/- 30%, which is considered acceptable. An accuracy range of better than +/- 5% is considered almost unattainable with current measurement

DigiVac Launches Novel Vacuum Gauge For High Vacuum Region At AVS

DigiVac Launches Novel Vacuum Gauge For High Vacuum Region At AVS DIGIVAC— is excited to exhibit New Technology at AVS 2015—the 62nd International Symposium and Exhibition on October 18th-23rd at the San Jose Convention Center, in San Jose, California. OptraVac | Addresses the Need of High Accuracy By Direct Measurement in the High Vacuum Region (1×10-3 to 1×10-7 Torr). OPTRAVAC is the only Isolated and Passive sensor technology on the market. Unlike any other medium and high vacuum measurement technology currently available, it is immune to electromotive pulse (EMP), electrical interference, and magnetic interference. Why is this important? You avoid sensor degradation and inaccurate readings. The novel vacuum gauge

Taking the Guesswork Out of Pumpdown Curves

Taking the Guesswork Out of Pumpdown Curves Everyone knows that keeping track of your vacuum system pumpdown curves is important and a valuable asset in troubleshooting leaks in the system. However, creating pumpdown curves aren’t always easy and can take too much of your valuable time! Keeping Watch Who wants an unexpected shut down? No one! Keeping a constant watch on your vacuum process system’s performance and operation is vital to spot the onset of a potential problem before it becomes a REAL PROBLEM ruining your process run and potentially causing a system shut-down. There are some simple and practical

3 Key Features Your Vacuum Pump May Desperately Need

3 Key Features Your Vacuum Pump May Desperately Need Vacuum Pumps—the Work Horses of Many Industrial Processes Vacuum pumps are an integral part of many industrial facilities and are used in many chemical processing and manufacturing applications. They are the work horses of vacuum processes and can often be in service 24 hours a day/7 days a week. With proper set-up of your system and timely preventative maintenance, your pump can operate effectively for years to come. You know how important preventative maintenance is, but there are other features like remote monitoring, data logging for tracking and pump down curve

Avoid False Readings When Vacuum Sensors Fail

Avoid False Readings When Vacuum Sensors Fail Ever feel like this guy? Damage to sensors and units alike is an inevitable facet of field work that can put undue stress on even a well-prepared crew, especially when time is of the essence. Vacuum sensors are calibrated in air. However, sensor contamination can occur easily in real-world applications leading to failure or false readings. Having multiple back-up vacuum sensors on hand that have already been factory calibrated to your specific vacuum gauge can save time, stress, and avoid the risk of inaccurate readings. Read on! Some sources of sensor contamination: Vacuum process byproducts Improper

Vacuum Tips: Beware Of The Pinched Vacuum Hose

Vacuum Tips: Beware Of The Pinched Vacuum Hose Industrial Process Troubleshooting: What Is Wrong With My Vacuum Gauge? Many discussions surrounding vacuum pressure and loss of suction focus on the pump’s deficiencies and leaky chambers, but there is usually little thought or concern regarding another integral part the system’s functionality: the vacuum hose that delivers the suction. Are you sure the hose you are using is vacuum rated? Or, will it collapse under pressure? Under Pressure It’s important to know the minimum pressure or maximum vacuum your vacuum system is pulling so you can purchase the appropriately rated industrial vacuum

Steps for Making Freeze Dryer Troubleshooting Easier

Steps for Making Freeze Dryer Troubleshooting Easier A vacuum pump has an important role in Freeze Drying. If the pump works and your chamber doesn’t leak then you’ve overcome the 2 most common problems and Freeze Drying happens. If the pump doesn’t work, then Freeze Drying doesn’t happen. But what constitutes working? And if everything seems OK but your process isn’t getting to the right vacuum level, where do you start troubleshooting? We recommend starting at the vacuum pump for 2 reasons: It is the easiest thing to quantify and troubleshoot It is the source of your vacuum Ever had a computer issue? The 1st thing you do is

What does vacuum pump maintenance and gambling have in common?

What does vacuum pump maintenance and gambling have in common? As Kenny Roger’s sang…”If you’re gonna play the game, boy You gotta learn to play it right… Every gambler knows that the secret to surviving is knowing what to throw away and knowing what to keep” Keeping up with industrial pump maintenance and being alert for poor vacuum performance will help you stay ahead of the game and not gamble its life away. Read on for easy steps for troubleshooting the performance of your vacuum system. No pump will deliver good results on a poor vacuum system, and the best pump

Making Vacuum Gauges Radiation Tolerant in High Radiation Environments

Making Vacuum Gauges Radiation Tolerant in High Radiation Environments Electronics, when exposed to radiation, will degrade and eventually fail, but methods can be adopted to extend their life. A customer who was integrating one of our 801W units into a system required the device to pass a radiation life test. It failed! Read on to see what we did to fix it… Most semiconductor electronic components are susceptible to radiation damage; radiation-hardened components are often based on their non-hardened equivalents, with some design and manufacturing variations to reduce radiation damage susceptibility. Under the effects of radiation, electronic components that aren’t hardened will:

Push Technology: Real Time Notifications From Your Vacuum Gauge

Push Technology: Real Time Notifications From Your Vacuum Gauge Real-time notifications are a glimpse into the future of vacuum pumps Have you heard the news? Arguably, this is not big news. In an ever-changing digital world we expect to be updated on the latest event as it is happening right now, not what happened five hours ago or even yesterday. From politicians to journalists to attorneys, technology has allowed real time information to reach and shape the ways in which we communicate and share data, among other things. And how true this holds when it comes to a critical application,
