Pressure for Emergencies

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Safely evacuating a building in emergency situations can be accomplished with the pressure stored in compressed air containers. An inflatable escape chute allows people trapped in locations up to four stories high to easily slide to the ground. With the proper pressure in the canister, the slide can be fully inflated in less than 6 seconds. The safety system is reasonably obscure when not in use, but a manual inside activation of the pressurized container brings the system to life. The system strictly uses pressure to ensure operation even during power failure situations.

With the sensors that are embedded in each unit, an operator can remotely monitor the air pressure in the tank to ensure that it is within correct limits and can also determine if tampering has occurred.

Manufactured by Slide to Safety, the company’s Rapid Evacuation System (RES) was developed after the Sandy Hook Elementary School shooting. However, it has potential applications in colleges, universities, commercial offices, residences, apartment buildings, motels and hotels, hospitals, government facilities or any multi-storied building.

Piezoresistive MEMS Pressure Sensors Growth

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Piezoresistive MEMS Pressure Sensors Growth

A new report is available for pressure sensors from MarketResearch titled, “Pressure Sensor Market by Technology Advancement, Growth and Forecasts 2027.”

Over the forecast period, increasing technological advancements in microelectromechanical systems (MEMS) technology as well as the rising adoption of this technology in connected devices are key factors driving growth. Of the analyzed technologies of piezoresistive, electromagnetic, capacitive, resonant solid state, and optical, piezoresistive technology is expected to enjoy the highest share in the market during this timeframe. Factors inhibiting growth include technical problems in integration and packaging processes and lack of a standard fabrication process.

While the market is segmented into automotive, oil & gas, consumer electronics, medical, industrial sector, and others, consumer electronics are expected to register significant share of revenue growth over the forecast period.

The Ups and Downs of Pressure

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

The Ups and Downs of Pressure

Higher and lower pressures can occur in what seem like unusual circumstances.  In plumbing, for example, much higher pressures occur if air gets into a water line and the faucet is closed quickly. Called water hammer, the effect causes audible noise or the banging of pipes. The hydraulic shock wave can, in some cases, cause severe damage since the pressure is so high. Draining the system is the usual solution to this problem.

On the down side, many people are surprised when they open a refrigerator door, close it and then try to immediately reopen it. The negative pressure in the refrigerator caused by this activity can be so extensive in well-sealed systems that it takes significant forced to re-open the door. The decreased pressure results from cooling of the warmer air entering the refrigerator. Based on ideal gas law, the pressure decrease could be 10% or more. In deep freezer units and those with the best sealing, the effect is even stronger producing even lower pressures.

Ideal gas law: P V = n R T

Where: P is the pressure, V is the volume occupied by n moles of any gas at temperature (T) in Kelvin and R is the gas constant.

Pressure and the Polar Vortex

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Pressure and the Polar Vortex

It’s baaack. It has been 4 years since a polar vortex disruption brought artic weather to the Northern Hemisphere. In the 2014-2015 winter, it meant historically cold temperatures and high snowfall in many areas.

While a polar vortex (a large area of low pressure and cold air that surrounds both of the Earth’s poles) always exits, other weather conditions can disrupt it and cause its effect to spread. Normally, the counter-clockwise (vortex) airflow keeps the colder air near the pole. The disruption is detected by pressure measurements in the stratosphere – not a ground level. While, a variety of pressure levels are used to mark its position, the 50 mb pressure surface is most often used to identify its location.
