Pressure Sensors, Mass Flow Sensors & Oxygen Sensors is our Experience

Posifa's vacuum sensors are known for high resolution and performance. These sensors are excellent for measuring small amounts of vacuum changes. Typical applications include but are not limited to freeze drying, degassing, cryogenic storage, vacuum glove boxes, and more. Pressure sensors can also be used for vacuum measurement applications where resolution requirements are lower. 

There are two types of pressure sensors used for negative pressure or vacuum pressure applications: gauge sensors and absolute pressure sensors. The reference pressure is the differentiating factor between these 2 types of sensors. The diagram below illustrates how the different methodologies work.

Various technologies are used to make pressure sensors. 2 of the most common include piezoresistive and capacitive pressure sensors. Both can be used for gauge, differential, or absolute pressure measurement. While piezoresistive is found in low-cost sensors, there are situations where a capacitive pressure sensor is better suited for the application.

The Bartels Conference 2022 is on May 12, 2022, from 1 pm to 5 pm Central European Time, which translates into 7 AM Eastern Standard Time. We know the time is difficult. Therefore, all registrants will be able to access the webinar after the event. The conference is in English and free of charge.

It's an understatement to say "the world has changed" over the past 25 years. Aside from the multitude of external factors surrounding our lives, the traditional method of transacting business has changed, but not all of it is helpful for engineers in the sensors world.

In many applications and industries, it is not uncommon to come across the risk of excessive pressure, or overpressure, within the pneumatic or hydraulic network of equipment, especially in facilities with a high degree of automation. If this phenomenon is not controlled properly, it may cause permanent damage to equipment and production lines which is why pressure sensors are commonly used as some form of protection in several operations such as industrial, ...

Medical ventilators supply air or other gaseous mixtures to patients through the use of pressure. These devices are used when patients require assistance breathing or are entirely unable to breathe on their own. One vital component that these systems use to function is a pressure sensor.

Choosing the right pressure transducer for a specific application can be overwhelming. There is a vast array of choices, many of which duplicate performance. If you don't find the right combination of features, many manufacturers don't offer modifications or customizations without a large order. That leaves you with little choice but to try to make do with the closest fit.
