All Sensors Corporation (Morgan Hill, California) has announced the high-pressure model of the "General Purpose Small Pressure Sensor BLC Series." In addition to the low-pressure model with a pressure range of 250Pa to 7.5kPa (1inchH2O to 30inchH2O), the addition of the high-pressure model with a pressure range of 35KPa to 1035kPa (5PSI to 150PSI) allows for absolute pressure measurements from 15PSI to 150PSI and differential pressure measurements from 5PSI to 150PSI. It is designed for measuring non-corrosive or inert gases and dry air. With a drive voltage of 0.9 to 1.8 VDC, it is a compact, low-voltage, and low-power consumption sensor, making it ideal for small electronic devices and battery-operated equipment. ■ Applications Application fields: Medical devices, medical testing equipment, environmental measurement, environmental testing, HVAC, portable/handheld devices, and other areas requiring micro-pressure and low-pressure measurements.

Pressure sensor providing advanced altitude information for smartphones Initially, Samsung obtained location information using accelerometers, gyroscopes, and magnetometers. To improve this, the Galaxy S4 was equipped with a pressure sensor. The pressure sensor provides today's accurate indoor location information. Around the same time, Apple also equipped the iPhone 6 with a pressure sensor. Today, many portable products are equipped with pressure sensors. Altimeters generally use absolute pressure sensors. They measure the phenomenon that atmospheric pressure decreases as altitude increases, using a vacuum as a reference. These two are related by the following equation. <For more details, please see the detailed page>

Gas control, medical control systems, air compressors, and vacuum pumps are all possible equipment used in medical or veterinary offices. In all these systems, monitoring and controlling pressure is necessary to achieve appropriate, efficient, and safe values. The Patton medical gas control panel for nitrogen displays the supply (95 psi) and outlet (82 psi) pressures. While gauges are commonly used so that medical professionals can easily observe pressure during procedures, installing micro-electromechanical systems (MEMS) sensors on the back of the panel allows for local or remote monitoring of data. With digital data, it is possible to execute alerts and use archived data to properly maintain oxygen supply levels during surgery.

If water damage occurs inside the house, especially on the walls, it is recommended that restoration companies sample the air to determine whether dangerous mold has developed. This sampling method simply involves collecting air near the affected wall in a container for laboratory analysis. Low-cost tests obtain volumetric measurement samples by inhaling air at a constant speed for a set period. After that, the samples can simply be analyzed in the lab. In addition to mold spores, air sampling can also be conducted for fibers such as pollen, insect parts, skin cell fragments, asbestos, glass fibers, cellulose, and clothing fibers, as well as organic particles like ceramics, fly ash, and copitoner. Under poor environmental conditions, much more accurate and precise measurements can be sought by verifying compliance with regulations on a regular or continuous basis. Digital control pumps can adjust airflow from 5 to several thousand (usually between 4000 and 5000) ml/min using a built-in airflow indicator. For example, SKC's pocket pump displays airflow and pressure and is equipped with both constant flow mode and constant pressure mode. In this case, the pressure is 28.94 inches of mercury (inHg).

The "static pressure" of a fan is one of the two parameters that define the performance of the fan. The more common parameter is "the amount of air the fan moves per minute or per hour." The static pressure of a fan is the resistance pressure that the fan must overcome to move air in the desired direction. For PC gamers, both high airflow fans and high static pressure fans are required. High static pressure fans are used in areas where PC components obstruct airflow, such as in front of radiators, CPU coolers, GPU coolers, and hard drives. High static pressure is necessary to create airflow in enclosed spaces. The Air Pressure Fan Masterfan Pro 120 (Cooler Master) is ideal for blowing air into high-temperature components or tight spaces. In low-pressure situations, digital output pressure sensors like the All Sensors DLLR Series can accommodate manufacturing, installation verification, or ongoing operational measurements.
