Understanding the difference between gauge and absolute pressure sensing measurements is easiest to visualize with piezoresistive type pressure sensor and a diaphragm that deflects with pressure. For both types of measurements, pressure is applied to the top of the thin diaphragm. With the gauge pressure sensor, the back side is vented to atmosphere. This could […]

Low Pressure Filtering of a Pressure Sensor’s Input
The Problem In some applications, high-frequency pressure transients may be present that distort the sensor’s output and degrade its ability to read the underlying changes in pressure. This can especially be a problem in low-pressure applications, such as medical measurements where discerning subtle differences is essential to successful diagnosis and monitoring. A common, well-known solution […]
All Sensors adds pressure ranges to its compact sensor series
All Sensors Corporation of Morgan Hill, California has announced the availability of additional BLC Series pressure ranges. The BLC Series now includes high pressure ranges from 5 psi to 150 psi. This device series offers design engineers excellent performance for pressure ranges of ±1 inH2O through ±30 inH2O, and now 5 psi to 150 psi […]
What’s new in low pressure sensing?
At Sensors Expo 2018, Dale Dauenhauer, the General Manager of All Sensors explains All Sensors’ role now that the company is part of the Sensor Group at Amphenol Corporation. All Sensors was acquired for its low pressure sensing technology. As part of Amphenol, their activities will mainly be focused into the medical market in applications […]
How have pressure sensors changed over the last few years?
At Sensors Expo 2017, Jim Brownell, sales manager for All Sensors, shows the progression of microelectromechanical system (MEMS) pressure sensing over the past 30+ years from his company’s perspective. Starting with the A or alpha package that was created in the early 1980s, a packaged element pressure sensor had two integral ports and six leads […]
Communicate Using Nasal Pressure
Blink once for yes, twice for no. This technique is frequently used in movies, TV and real life to communicate with a person who is severely injured. It is also used to communicate with “spirits” and even as a secret code for perfectly healthy individuals. In either case, the communications are always limited to yes […]
High-res pressure sensor measures over 0.5 to 60-in. H2O range
A new low-pressure sensor called the DLHR Series works over lower pressure ranges of 0.5 to 60 in. H2O, an improvement over previous devices. Developed by All Sensors Corp., the DLHR Series is said to provide higher resolution than any other fully compensated low-pressure sensor currently available on the market. All error compensation takes place […]
High Resolution, Digital Pressure Sensors
At Sensors Expo 2016, Han Mai from All Sensors provides information about the company’s DLH Series of high resolution, low cost digital pressure sensors. The sensors have either an I2C or SPI digital interface option. For more information about the DLH Series pressure sensors, click here.
Pressure Sensors Address New Markets
In 2015, All Sensors pressure sensors did not target applications that contacted fluids. Now they have two different series that specifically target these types of applications Similar to the company’s existing products, the stainless steel media-isolated SPM 401 series employ a microelectromechanical system (MEMS) sensor design using an etched silicon sensor diaphragm with piezoresistive sensing […]
DLV Series Low Voltage Digital Pressure Sensor
All Sensors Corporation of Morgan Hill, California has announced a new DLV Series Low Voltage Digital Pressure Sensor. The DLV Series is based on the DLVR Series Pressure Sensors. This new device series offers design engineers excellent performance over middle pressure ranges of 5 to 60 psi compared to the DLVR low pressure ranges of […]
