Five major applications of pressure sensors

Release time:

2023-06-06 09:02

The five major applications of pressure sensors are as follows:
The particularity of installing pressure sensors:
For pressure sensors, the installation method directly determines their application, generally measuring stability. Generally, sensor installation is directly fixed to the equipment to be measured using threads,
The adhesive installation of sensors is a method rarely used for sensors. The correct bonding method for pressure sensors is crucial. This information will help testing engineers provide better guidance and achieve better results when bonding some special types of sensors
In the bonding process of pressure sensors, the amount of adhesive used plays a crucial role in whether the sensor can achieve good frequency response.
Before installing the pressure sensor, it is necessary to clean the surface to be installed with a hydrocarbon solution, which should not be too thick or too thin. A suitable thickness will have a good bonding effect. There are many precautions for using hot adhesives, and the most important thing is to pay attention to the solidification time of the hot adhesive during the installation process.
Five major applications of pressure sensors:
With the continuous improvement of automation level of pressure sensors in China, there are higher requirements for various parameters, so there are five major applications:
1. Detect car exhaust
A solid electrolyte gas sensitive ceramic material is used to develop an oxygen pressure sensor for automotive exhaust monitoring, which measures the oxygen concentration in exhaust emissions to detect the air fuel ratio of the engine.
2. Detecting vehicle humidity
The characteristics of humidity sensitive ceramics are wide humidity measurement range, fast response time, and simple production process. They are the main materials for automotive humidity pressure sensors. Suitable for detecting frost and condensation on car window glass, as well as air humidity in the intake section of the engine carburetor.
3. Detecting car temperature
A car typically requires more than 10 ceramic temperature sensors to detect temperature. Another type of positive temperature coefficient PTC thermistor is made by mixing BaTiO3 as the main material and sintering it with metal oxides.
4. Check the working status of the cylinder
Piezoelectric ceramics based on Piezoresistive effect can monitor the working state of cylinder. The piezoelectric ceramic knock sensor is composed of a piezoelectric ceramic oscillator, a metal sheet, a sealing gasket, a metal shell, etc.
5. Guiding safe driving of automobiles
The pressure sensor based on Piezoresistive effect is used as a car reversing anti-collision alarm device, also known as an ultrasonic Parking sensor or reversing sonar system, and is especially suitable for large vehicles such as extended loading vehicles, heavy trucks, mining vehicles, etc.
