Uses and Benefits of Pressure Sensors |
Posted: July 4, 2019 |
Pressure sensor is an electrical or mechanical measuring instrument for collecting information and converting it into an electrical unit. An environment is analyzed, this way the data processes can be controlled from. These sensors are mainly used in industrial or IT sector. Pressure sensors measure pressures and associated pressure differences, in particular gases and liquids. A pressure sensor works like a transducer, because it generates an electrical signal in response to the pressure imposed. Pressure sensors are used for the control and monitoring of thousands of different types of applications. Another name that is often used is pressure transducer, pressure transmitter, pressure transmitter, pressure indicator and pressure gauge. A pressure sensor can be supplied with an analogue output such as 0.5… 4.5VDC, 0… 5 / 10VDC or 0/4… 20mA or digital output such as RS232 / 485, CAN open or Hart protocol. The sensor can also be provided with all kinds of ship labels such as GL, RINA, LLoyds, Veritas, etc. ATEX, IS, CSA inspections are also possible. Why do you measure pressure?You measure pressure for something to be arranged in a process, or you can say, you measure the pressure to control the process. For example, if you want to measure the pressure in a pipe, it must be 5 bar. The pressure transmitter is in between. If the pressure becomes too high, you can open a valve so that the pressure drops again. Benefits of Pressure Sensors
Piezoelectric Pressure Sensors for Dynamic Pressure MeasurementsPiezoelectric pressure sensors are used in many dynamic pressure measurements. Some examples include: compression, pulsations, flow, cavitation, hydraulic and pneumatic pressure variations, high-intensity sound, shock and shock wave, ballistics, explosion (detonator, explosion flash), bomb ignition studies, and other dynamic pressures from 0.690 Pa to> 690 MPa). The ability to measure small pressure fluctuations of highly static pressure levels is a special property of piezoelectric pressure sensors. The ICP®-reinforced output makes the sensors particularly suitable for use in dirty and underwater environments as well as applications in the field where long cables are required. Although piezoelectric pressure sensors are generally recommended for dynamic pressure measurements, due to their long discharge time constant which extends their low-frequency characteristic, some quartz pressure sensors can also be used to measure static as well as quasi-static pressures for a short time (few seconds). Since no low noise cables and charge amplifiers are required, the cost per channel of an ICP® sensor system is considerably lower and very cost-effective. Due to the low impedance output of the ICP® sensor, its excellent signal-to-noise ratio, its ability to drive long coaxial cables, it is ideally suited to virtually all dynamic pressure applications within the temperature range of -196 ° C to 135 ° C. be deployed. For applications with higher temperatures, The robust construction of the piezoelectric pressure sensor allows a very extensive and linear measuring range, allowing PCB® to deliver reliable calibration certificates for most models based on the measurement of the 100% and 10% points of the full range of the model. Due to their limited measuring range, multiple strain gauges or piezoresistive sensors would be required to allow the range of measuring options of a piezoelectric sensor. Standard or specialized sensors as well as mounting adapters are available to facilitate installations in existing setups.
