How To Use Wireless Industrial Pressure Sensors?
Wireless industrial pressure sensors are often found in applications for the monitoring of the status of machinery and systems in manufacturing industries and in process control. In addition, the fact that these devices communicate with the control system through wireless communication means that they could be utilized in the remote control of various equipment. The common design for these pressure sensors, such as Keller pressure sensors, is based on the principle of piezoresistance in which the resistance of the material is directly proportional to the pressure that is applied on the material. There are various applications of wireless industrial sensors, because the fact that they are wireless offers several benefits.
Some of the benefits of wireless industrial pressure sensors include circuit integration, ease of networking, transducer miniaturization, better signal-to-noise ratio, and multi-point sensing. Such devices can also be utilized for determining the bottomhole pressure in the petroleum industry. How do various industries make use of networks of these sensors, including a differential pressure transmitter? Wireless sensor networks can be applied for the checking of the different process variables in petroleum production activities, the monitoring of the different process variables in manufacturing, and watching over the many process parameters in waste/wastewater facilities. There are so many possibilities for using these sensor networks but it is observed that they tend to be often used in industries where materials are flowing, such as in the chemical industries, metal industries, paper and pulp industries, beverage industries, and food industries.
As mentioned above, the basic principle of sensors is that the current flowing through the piezoelectric materials is proportional to the amount of pressure. For regular pressure transducers, this electric current travels through electric wires. However, a more convenient arrangement is the use of wireless pressure sensors. These are equipped with the capability to create radio signals that transmit the information to the control panel or computer. Some of the specific applications of wireless pressure sensors in industries include leak testing, measurement of the flow of liquids or gases, and checking on the gas and liquid pressure in certain machinery to ensure proper operation and safety. These devices could be a differential pressure sensor, sealed sensors, gauge sensors, or absolute pressure sensors.
Wireless industrial pressure sensors use a force collector for detecting the pressure. This sensing diaphragm could be potentiometric, piezoelectric, optical, capacitive, electromagnetic, or piezoresistive. These systems can be classified under the category of direct pressure measurement. On the other hand, it is also possible to measure the pressure indirectly. These sensors perform measurements of other variables, such as the flow of ions, changes in the thermal conductivity of gas, and resonant frequency changes in a part of the sensor or transducer. Meanwhile, an industrial processing system usually requires a large number of pressure detectors. Thus, a wireless sensor network is often utilized to allow a computer to conduct the monitoring activities and perform analysis. In this way, process control can be automated for a more efficient industrial process and to minimize costs.
