The Pressure for Healthy Teeth

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 Pressure for Healthy Teeth

Pulsating dental water jets or oral irrigators have been used for dental healthcare for over 50 years. The pulsating stream of water and special tips provide a treatment for braces, sensitive teeth, plaque and gingivitis. One manufacturer offers countertop water flossers with 3, 6, or 10 pressure settings ranging from 10–90 or 10-100 PSI and cordless water flossers with 2 or 3 pressure settings from 45–75 PSI.

Water Flossers - Countertop vs. Cordless

The pressure range and adjustability vary depending on the type of water flosser.

With the lowest (1) setting of 10 PSI and the highest (10) setting of 100 PSI, the ten adjustments steps on one model provide approximately 10 psi increments between steps. The user does not have to relate to the actual pressure but just know that if they have sensitive teeth they want to start with the #1 step (10 psi). Experienced users often use the higher-pressure settings. Since the pressure settings are all relative, a pressure sensor is not required in the flosser. However, as in any product that involves pressure, the design pressures need to be verified by laboratory testing to establish the typical and maximum pressure settings and verified in manufacturing for consistent quality using highly accurate pressure sensors.

Steam 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.

Steam Pressure

Today, displacing gasoline or diesel powered engines by electrically-powered motors is the goal of extensive renewable energy efforts. Before the fossil fuel powered machines, the steam engine powered the Industrial Revolution and dominated industry and transportation for 150 years with coal providing the primary fuel to heat the water in the boiler.

Live steam or steam under pressure created by boiling water is still used to operate some machinery and has a cult following in scale model trains. For safety purposes, the engineer monitors the pressure in the boiler.  The pressure is measured by a mechanical gauge and controlled by a safety valve that relieves excessive pressure. Typical operating pressures are in the 200 to 250 psi range. In these trains, any digital sensing technique would be quite out of place.

Several pressure measurements can be made for the engineer to safely control the steam engine.

Progression of MEMS Pressure Sensing

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.

At Sensors Expo 2017, Jim Brownell, one of All Sensors’ sales managers, explained the progression of microelectromechanical system (MEMS) pressure sensing over the past 30+ years from All Sensors’ perspective.

Power Washing or Pressure Washing?

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.

Power Washing or Pressure Washing?

Washing your car or hosing off the driveway typically uses about 40 to 50 PSI of pressure. In contrast, the pressure in a power washer or a pressure washer can be 40 to 200 times higher. While these terms are sometimes used interchangeably, a power washer uses a high pressurized stream of hot water and pressure washer almost always uses high pressure cold or normal water. The operating pressure of the pressure washer varies considerably depending on the level of the machine.

Commercial grade pressure washers, can be from 1000 to 4000 PSI with pressures below 2000 PSI more common in more affordable units. For example, one electric pressure washer operates at 1600 PSI (max) and delivers 1.2 GPM (max). Another example, operates at maximum volume of 1.6 GPM and a maximum pressure of 2000 PSI.

Semi-pro pressure washers have a significantly higher power output, PSI and GPM ratings than commercial washers with 1800 to 3000 PSI and 1.6 to 4 GPM being typical ranges. These units typically use only cold water. Unlike an electric unit that operates at 1800 to 2000 PSI max, a gas type unit can deliver 2500 to 4000 PSI.

At the high end, professional pressure washers are rated at 3000 to 8000 PSI and 2 to 8 GPM and deliver cold and hot water. Pressure regulation is common in these units that allows decreasing the pressure for mixing with detergent, increasing the pressure for removing mold from brick or decreasing the pressure to sanitize commercial kitchens with hot water. Common applications of profession pressure washers include car washes, kitchens, meat packing facilities and more.

All Sensors CPA 602 Series media isolated ceramic amplified pressure sensors can address pressure measurements in pressure and power washing systems up to 6000 PSI.
