New At AVS: OptraVac | Highly Accurate Direct Vacuum Gauge

Posted by Tim Collins on Oct 22, 2015 10:00:00 AM

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 1x10-5 to 1x10-7 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 technologies  2. Many academic and industrial processes use a mixture of gasses other than Nitrogen, without establishing an appropriate correction factor, the accuracy of all indirect gauges is compromised Since most indirect measurement gauges are calibrated in Nitrogen, measuring pressures of different gases with different properties requires a correction factor. Gas correction factors are often based on a particular gas. Therefore, applying gas correction factors for a mixture of known or unknown gases becomes more challenging. This is especially true if the ratio of gasses changes throughout the process. If there was a solution to these problems, would you want to learn more? Please consider giving us your feedback on a new digital vacuum gauge that avoids these problems by completing a short survey.

DigiVac Launches Novel Vacuum Gauge For High Vacuum Region At AVS

Posted by Tim Collins on Oct 20, 2015 1:51:51 PM

DigiVac Exhibiting at the 62nd AVS International Symposium and Exhibition Booth 622 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 (1x10-3 to 1x10-7 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.

Avoid False Readings When Vacuum Sensors Fail

Posted by Tim Collins on Sep 11, 2015 11:12:04 AM

  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!

Vacuum Tips: Beware Of The Pinched Vacuum Hose

Posted by Tim Collins on Aug 19, 2015 2:00:00 PM

  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?

The Vacuum Terminology You Should Know

Posted by Tim Collins on Apr 16, 2015 8:23:44 PM

Introduction: Vacuum terminology has evolved over time.  In order to describe what you are looking for, it is helpful to have a guide that describes what different terms mean so people from different industries can communicate with one another.  We'll start from the beginning and focus on vacuum measurement and control.

Accuracy of Thermocouple Tubes Without Calibration

Posted by Tim Collins on Mar 12, 2015 12:55:00 PM

Unexpected sensor failures, breakage and contamination happens to all of us. Hopefully you have a spare on hand when a sensor breaks in the field. You quickly switch out your vacuum tubes and proceed without hesitation. Unfortunately it's rarely that easy - there are small electrical differences between each sensor; thus, your backup sensors will produce different readings on different vacuum gauges without calibration.   Unfortunately, factory recalibration isn't always an option at the time. This should raise some logical questions with technicians; how reliable and accurate are the readings produced by backup vacuum tubes? We set out to answer this question by performing an experiment in the DigiVac shop.
