Pressure sensors are very popular in our times as they are the best systems for measuring pressure when it comes to fluid substances. When a container is full of liquid, for instance, and more liquid is released in the container, the sensor detects the increase in force and transforms it into an electric charge. After the transformation, the signal obtained will be transmitted further to the interpreter device. This is how equipment like this is functioning.
The force parameter is not the only one measured; there are also secondary measurements like the substance amount or the flow of the liquid/gas. These devices can measure a lot of things. The reading can be either static or dynamic.
During the steam age the first devices were made and they became very popular. Since then, the technology has evolved a lot, and they have adapted. Their popularity is still the same in our times. They can be split in three categories depending on how they work: variable capacitance, strain gage and piezoelectric.
The pressure sensor can be found in different shapes and designs; they can be classified after performance or price, after the range of measurement and the temperature range of use. There are some dynamic sensors that can measure rapid changes in speed or pressure, these ones have a high performance and are made of quartz.
The construction of strain gages systems involves 2 things: a diaphragm and a strain gauge. The diaphragm is useful for the detection of the increasing force in the fluid. Then the information is passed to the strain gauge, which will generate a resistance equal to the force. The resistance can be measured with the aid of a DAQ or Data Acquisition System.
When it comes to the devices that use variable capacitance, these are made of two metal plates. Actually it is one metal plate and a metal diaphragm. When the force changes, the distance between the plates changes as well and this indicates the difference in pressure. Like the accelerometer, these devices are more stable than others but they do not function well in high temperature conditions. Also they are harder to assemble then the other types.
The piezoelectric systems have a construction layout that is based on quartz crystals. The quartz has a natural property which makes it create electrical charges at the detection of strong forces. The signal has to be boosted after it is generated. Their disadvantage is low resistance to vibrations and shocks.
The signal which is transmitted by the device is weak in the majority of cases. The measure unit is mV= 0,001 Volts. The voltage outputted depends on the force intensity. A voltage equal to zero means a pressure level that is zero (zero Bars). The signal does not exist in this case. But when the value is 5V the corresponding value will be 5 Bars.
Pressure sensors are devices that are very common in our days. They are used in many industrial domains. For example, they have a good role in the food industry. Regardless of their type, they are good tools for measuring the force generated by different fluids. But they also measure the fluid speed, the level of a fluid inside a container or many other valuable details.
