Dealing with the Pressure in Storage Tanks

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. In this blog we’ll be discussing the pressure in storage tanks.

Dealing with the Pressure in Storage Tanks

The weight of any liquid results in a pounds per square inch (PSI) or other values of pressure reading depending on the height of the fluid and its density. In addition, due to volatility, there can be additional pressure associated with a confined liquid. This is especially true for gasoline and other petroleum based fuels. For safety purposes, pressure readings are made at many locations in a fuel storage and transportation facility. For on the spot readings by an operator, many readings continue to be based on using mechanical pressure gauges. However, with the ease of wirelessly transmitting readings, and availability of pressure sensors that can handle interfacing to a media such as gasoline, fuel oil, diesel or others, the electronic data can be sent for remote collecting, monitoring and file keeping. Sensors such as All Sensors CPM 602 ceramic sensors can provide data from 30 to 6000 PSI.

Monitoring the Transportation of Liquids

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. In this blog we’ll be discussing the transportation of liquids.

Monitoring the Transportation of Liquids

The transportation of liquids can take many forms from pipelines to trucking to shipping and more. In many cases, monitoring the transportation process requires high pressure sensors with media isolation. Ceramic pressure sensors are a frequently used technology to satisfy both high pressure and media isolation requirements. The highly media compatible ceramic material can be exposed to many harsh chemicals. However, even water can pose a threat to normal sensors that are not intended for contact with materials beyond non-corrosive, non-ionic working fluids. The ceramic pressure sensor design can withstand maximum pressure range of up to 6000 PSI. For sensors such as, All Sensors’ newest CPM 602 series, the ratiometric sensors with total error better than 0.4% FS and ability to operate from supply voltage of 2 to 30 VDC in operating temperatures from -40 to 135°C further simplifies the monitoring process.

Media Isolated Pressure Sensors

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. In this blog we’ll be discussing media isolated pressure sensors.

Media Isolated Pressure Sensors

Unlike many other sensor applications, pressure sensors frequently have to contact some pretty nasty chemicals. Sensor manufacturers usually qualify their sensors for restricted usage with statements such as “intended for use with non-corrosive, non-ionic working fluids such as air, dry gases, etc.” This means that the user who has an application that does not meet these criteria, either cannot use a product that meets all the other application requirements or has to take steps to protect the sensor and assume any risk regarding the protection methodology.

In contrast, sensors designed specifically for harsh environments open many new applications in areas including medical, environmental controls, plant and mechanical engineering as well as automotive. In many cases, the technology changes for these more rugged sensors from a silicon, microelectromechanical system (MEMS) material to a ceramic material but still retains a monolithic design. A flush membrane makes it easy to interface these types of pressure sensors to hydraulic fluids and even extends the pressure range up to 6000 PSI. With the CPM 602 series, All Sensors now participates in these more demanding applications.

A ceramic pressure sensor overcomes many of the limitations of silicon-based MEMS pressure sensors.
