Learn More About High Frequency Pressure Sensor

The high-frequency pressure sensor is designed for the special requirements of the high-frequency system for the pressure sensor. Experiments and other scientific experiments and modern instrumentation.

It is necessary to measure some dynamic pressure waveforms, amplitudes, and effective values with high frequency of change and rapid rise of pressure waveforms without distortion. This requires the pressure sensor used to have high natural frequency, extremely short rise time and wide and excellent response frequency .To ensure sufficient dynamic pressure measurement accuracy. It is suitable for working conditions with strong vibration and large impact.

Pressure detection of gas explosion.

Generally used in pipeline gas explosion experiments, the pressure range is generally 0.5MPa ~ 10Mpa. According to the amount of gas mixed in the experiment, the explosion space and the installation location, the pressure range is different.

Underwater blasting experiment.

Generally, the sensor is installed on the inner wall of the underwater instrument. The pressure sensitive element of the sensor is exposed to the test environment. The change of water pressure before and after the explosion moment is monitored. The pressure data is collected by a high-frequency acquisition instrument and restored to a pressure waveform to truly restore the explosion. Instantaneous pressure changes in the surrounding environment.

It is similar to the pressure detection of such explosion conditions. Generally, a high-frequency pressure sensor with a response bandwidth of 0-200KHz is selected. The rise time of the sensor is measured in microseconds, and the overall experiment is relatively short.

Pressure detection with frequent reciprocating changes.

For example, pressure detection of reciprocating pumps, pressure detection of hydraulic machines that are frequently pressurized and depressurized. Generally, the pressure change of air pressure is relatively fast, and the pressure change of liquid pressure is relatively slow. According to actual working conditions, a high-frequency pressure sensor with an appropriate bandwidth can be selected.

High-frequency pressure sensors are generally used for pressure detection of rapidly changing high-temperature media. The maximum measurement temperature is 200°C. Long-term pressure measurement, the response bandwidth is 1-2KHz.

The pressure sensor we commonly use has a measurement range of about 100MPa. But in the industrial production process. We may need to use higher pressure. Such as 300MPa, 600MPa. At this time, conventional pressure sensors are no longer applicable.

High Pressure Sensor adopts the unique integrated structural elastic element of high-precision foil strain gauge, which has stability and reliability. It can be used for the measurement of high pressure and ultra high pressure. It is especially suitable for measuring the pressure of hydraulic, pneumatic and other media. Even used in harsh environments such as sewage, steam, mild corrosive, gas measurement. Solve the various needs of customers.

There are four common pressure sensors:

  1. Strain pressure sensor
    A strain gauge pressure sensor is a sensor that measures pressure mainly by measuring the strain of an elastic element. According to different materials, strain elements are divided into metal and semiconductor. When conductive and semiconducting materials are mechanically deformed, their electrical resistance changes.
  2. Piezoresistive pressure sensor
    The piezoresistive pressure sensor is a sensor made of the piezoresistive effect of single crystal silicon material and integrated circuits. When the single crystal silicon material is subjected to force, the resistivity will change. At this time, through the measurement circuit, an electrical signal proportional to the force change will be output. Different from the adhesive strain gauge, the measured pressure is mainly felt through the silicon diaphragm.
  3. Capacitive pressure sensor
    Capacitive pressure sensors mainly use capacitance to convert the measured pressure into a pressure sensor with a changed capacitance value. The electrode of the capacitor is a circular metal film or a metal-plated film. When the film is deformed under pressure, the capacitance changes and an electrical signal is formed.
  4. Piezoelectric pressure sensor
    Piezoelectric pressure sensor adopts piezoelectric effect. It uses electrical components and other machinery to convert pressure into electricity. It is an instrument for related measurement work.

In general, a pressure sensor is mainly composed of three parts: a load cell sensor (also called a pressure sensor), a measurement circuit, and a process connection. It can convert the physical pressure parameters such as gas and liquid felt by the load cell sensor into a standard electrical signal (such as 4~20mADC, etc.). Measurement, indication and process adjustment are carried out by supplying secondary instruments such as indicating and alarming instruments, recorders, and regulators.
