The capacitance pressure sensor is a pressure measurement device, which converts an applied pressure into a current signal, Like 4-20mA. Capacitive pressure transducers are used in many control and monitoring applications, such as flow, airspeed, level, pump systems, or altitude. Working Principle A capacitor consists of two parallel conducting plates separated by a small gap. …
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 …
The sensing element of a pressure sensor, the part that turns the pressure into an electrical value, is independent of the type of pressure sensor and its sensing method. Environmental conditions where the sensor will be used and the media being measured will influence which sensing element should be used. This will have been considered …
Do Absolute, Gauge and Differential Pressure Sensors Measure Pressure Differently? Read More »
What issues need to be considered when choosing a pressure sensor? What kind of pressure is measured by the sensor, what kind of accuracy the sensor needs to achieve, how is the temperature resistance of the sensor, etc. The following is a detailed introduction. What pressure does the sensor measure? The first thing to consider …
In order to select the appropriate pressure sensor for an application, you’ll need to consider the purpose of the measurement you’re making. If the measurement should not be influenced by local atmospheric pressure changes, you most probably need an absolute pressure sensor. When the application is using air pressure sensor to determine elevation, such as …
What’s the difference between absolute, gauge and differential pressure sensors? Different applications require different ways of measuring things. In electronic systems, as an example, sometimes we want to know the voltage across a specific component. Other times we’re only interested in the difference in voltage between two points in the circuit. It’s a similar situation …
