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

The Wireless Future Of Vacuum Gauges

The Wireless Future Of Vacuum Gauges You may have heard the saying, ‘the internet of things,’ but what does this mean and what does it have to do with vacuum gauges? This popular phrase means that everyday objects become much more powerful with network connectivity. Connected devices exchange data, and, in the process, change the way we use the device. A new symbiosis between humans and technology is now a reality, and the implications – along with the possibilities – are seemingly endless. Now, what about those vacuum gauges? Introducing the world’s first Bluetooth Vacuum Gauge, The Bullseye Precision Gauge

3 Benefits of Vacuum Distillation in Low and Medium Vacuum

3 Benefits of Vacuum Distillation in Low and Medium Vacuum When the general public thinks about distillation, they are thinking moonshine or whiskey. In an industrial context, however, fractional distillation is a process by which vapor from a heated liquid mixture is condensed as it rises through a vertical column. Vacuum is a key component of this process. There are 3 key benefits of this method, and this post explains why, providing context in biomedical/biological research applications and in the methods used by oil refineries. How Fractional Distillation Works The aforementioned column, through which the condensed liquid mixture rises, includes

Vacuum Instruments For Lyophilizers | What You Need To Know

Vacuum Instruments For Lyophilizers | What You Need To Know Accurate, reliable vacuum readings during freeze drying processes is one of the bigger challenges faced by users of older lyophilizers, and an even greater challenge faced by those designing new systems. Freeze drying, whether done on an industrial scale (e.g., prepared foods, coffee, pet products) or in laboratory/pharmaceutical facilities (e.g., chemical compounds, vaccines, tablets), is a process of controlled dehydration wherein system vacuum levels greatly influence not only product quality, but also the efficiency of the entire drying cycle. Much of the drying profile hinges on proper integration of the vacuum instrument into the host drying system.  Retrofitting

PID for Vacuum System Automation

PID for Vacuum System Automation PID is an acronym for using a closed loop feedback system with the terms Proportional, Integral and Derivative.  While it uses calculus-type words, it is straightforward to configure and is what many industrial processes rely on for predictable automation.  It works on the principal of minimizing the error between the current vacuum reading and the desired set point vacuum pressure.   While PID can work on any closed system, it is also very useful for vacuum systems.  The balancing act is tuning the response to get your vacuum level to respond quickly, but also converge

Using a Vacuum Gauge in Food & Beverage Process Customization

Using a Vacuum Gauge in Food & Beverage Process Customization Removing oxygen in many food and beverage processes is critical.  If this is done manually, the process can be time consuming and result in inconsistent oxygen removal. However, this process can be automated by removing oxygen (O2) via recursive evacuating and backfill cycles. Automation can be accomplished with
