Pressure sensors are precise instruments, and like all instruments, they can sometimes fail. It’s difficult to tell whether a transducer is working well or not. This is because, without specialized equipment, you won’t be able to see or interpret pressure increase in a container in most cases. Do you want to know how to tell …

There are a variety of strategies for measuring the pressure in a gauge sensor. Most of them use a membrane that is fitted with an electrical component, such as a resistor, whose value varies when flexed. Nowadays, microelectromechanical systems, commonly known as MEMS, are utilized. Small and light structures are etched into silicon that can …
Pressure sensors are devices used to measure the pressure of liquids and gases. These devices are also known as pressure transducers or pressure transmitters, and which are used for controlling and monitoring pressure in a number of day-to-day applications such as touch screen devices, biomedical instruments, and automobiles. They sense pressure in a liquid or …

The basic measurement principle of piezoelectric sensors is simple. The crystals are placed in the sensor directly behind a thin membrane. This membrane then converts the pressure into a force onto the crystal, which then linearly reacts with a charge displacement, thus an electrical charge on the surface. This is a direct physical conversion of …

Each pressure sensor has several aspects that will influence how it operates and the applications the pressure sensor operates best for. When choosing a pressure transducer, these six criteria should be taken into account: Application and measurement type The standard type of pressure measurement involves: Absolute, gauge, vacuum, differential, bidirectional, and sealed gage. The application …
Differential pressure sensors are typically packaged with two ports to which pipes can be attached. The pipes are then connected to the system where the measurement is to be made. Industrial pressure sensors may be integrated into a standardized fitting, allowing it to be built into existing pipework. Typically, the two pressures to be measured …

Board level sensors are ideal for integrating onto a PCB, but they’re typically limited in the temperature range they support. You will also find that they’re not suited for monitoring most liquids and chemicals. Industrial gauge pressure sensors are an ideal alternative. They’re typically housed in a robust metal case, making them suitable for use …
Can Integrate a Gauge Pressure Sensor Into Circuit? Read More »
With so many different pressure sensing technologies available, there is no single way to integrate a sensor into your circuit. In most cases, you will be looking to connect your absolute pressure sensor to a microcontroller. Some sensors are so simple they require a significant amount of circuitry to condition the signal for use with …

With a sealed vessel as the reference point, a sensing technology is then applied to the surface of the vessel whose electrical characteristic varies with changes in strain. There are many different approaches to this. One common method is the piezoresistive strain gauge. These embed a resistor, (whose value changes with respect to mechanical strain) …
With a wide variety of pressure sensors available, it can be challenging to know which one is best suited to a specific task. When it comes to measuring air pressure, specifically for applications such as barometric measurements for weather or in altimeters, an absolute pressure sensor is the device of choice. However, your possible application …
