The air pressure sensor is used to measure the absolute pressure of the gas.It is mainly suitable for physical experiments related to gas pressure, such as gas laws, etc., and can also measure dry and corrosive gas pressure in biochemical experiments.
Bad pressure sensor instructions
The rated pressure range is the range of pressure that meets the standard value specified.That is, between the highest and minimum temperature, the sensor output complies with the stress range of the prescribed work characteristics.The pressure measured by the sensor during actual application is within this range.
Type of air pressure sensor
According to the measured physical quantity: such as: force, pressure, displacement, temperature, angle sensor, etc.; according to the working principle of the sensor: such as: strain sensor, voltage sensor, pressure -resistant sensor, inductor sensor, capacitive sensor, capacitance sensor, Optical sensor, etc.
The role of air pressure sensor
"The device or device that can be measured and converted into an available signal in accordance with certain rules is usually composed of sensitive elements and conversion elements."The air pressure sensor is a detection device that can feel the measured information, and can change the information that the detection feels is changed into an information output of an electrical signal or other required forms to meet the information transmission, processing, processing, and processing, processing, processing, and processing of informationRequirements such as storage, display, recording and control.It is the primary link to achieve automated detection and control.
Bad pressure sensor application
For those who like mountaineering, they are very concerned about the height of themselves.There are generally two methods for measurement methods with altitude height. One is through the GPS global positioning system, and the other is to measure atmosphere, and then calculate the altitude height based on the air pressure value.Due to the limitations of technology and other reasons, the general error of GPS computing altitude will be about ten meters. If it is in the woods or under the cliff, sometimes it will not even receive the GPS satellite signal.
Principles of air pressure sensor
In fact, the working principle of the air pressure sensor is not complicated. In short, the main sensor element of the air pressure sensor of the air compressor is a thin film and a thimble -opening control in the air pressure sensor.Instrument.When the pressure of the measured gas is reduced or increased, the film deformation drives the thimble, and the resistance of the resistor will change.The resistance of the resistor changes.Obtain a 0-5V signal voltage from the sensor element, accept the data collector after conversion, and then the data collector transmits the result to the computer in proper form.
