How Can Cascaded Pumps Get You Another Decade of Vacuum?

Cascaded Pumps – How They Can Get You Another Decade of Vacuum Introduction Cascaded pumps have a noticeable improvement to how far down they can pull vacuum when compared to a standalone pump. This particular combination of cascading pumps allows us to first pull down the vacuum of the first chamber by decreasing the pressure difference between the first pump’s inlet and exhaust. This reduced the load and thus gave it some more headroom. The second pump acts as a backing pump, which is similar to a turbo configuration. The test set up for how the pumps were arranged can

How can DigiVac Help with Altitude Simulation Testing?

What is Altitude Simulation? Altitude simulation testing is a process in which various materials and instruments are tested under varying degrees of air pressure – especially low – to test the adaptability and reliability of said materials and instruments. The materials and instruments can be anything from packaging materials to electronics – if it’s going in the sky, an altitude simulation test has probably been done or needs to be done on it. These tests are meant to simulate the different altitudes that these products would have to endure, and to check their reliability when under such pressure changes. There

How Durable Are The Corrosion Resistant Pirani Sensors?

CORROSION RESISTANT SENSORS | How Durable are They? Back in May, an article was released about the new corrosion resistant pirani vacuum sensors.  Previously, sensors were limited due to the exposed materials that were subject to corrosive gasses and aggressive etch processes, which we at DigiVac and our customers have observed as well.   Thus, with the introduction of the corrosion resistant pirani sensors, there exists an option for a more durable vacuum sensor.  These come with a protective coating, acting as a barrier against any aggressive gasses.  It either comes in a ceramic or Parylene coating. CERAMIC VS. PARYLENE Ceramic is advantageous in that it is highly corrosion resistant,
