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,

The Vacuum Terminology You Should Know

The Vacuum Terminology You Should Know 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. The term vacuum gauge has a meaning when talking with people in the scientific and industrial vacuum communities, and another meaning in the MRO market (Maintenance, Repair and Operations, such as HVAC).  In MRO, people are typically referring to fairly inexpensive all in

Accuracy of Thermocouple Tubes Without Calibration

Accuracy of Thermocouple Tubes Without Calibration 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
