Low pressure pressure sensor 7261
The resonance frequency is high, with high resolution, capable of measuring dynamic pressure and short-term static pressure from vacuum up to 10 bar!
The low-pressure sensor measures dynamic pressure and short-term static pressure from vacuum up to 10 bar. It is characterized by a high resonance frequency and high resolution. The charge signal generated by the sensor is converted into an output voltage proportional to the charge by a charge amplifier. The output voltage is not affected by the length of the cable connecting the sensor and the charge amplifier. The output of the charge amplifier is ±10V. The output of sensor 7261 reaches a maximum sensitivity of 0.001 bar/V.
basic information
The pressure to be measured acts on the quartz measuring element through the diaphragm. This quartz element converts the pressure into an electrical charge. The stainless steel diaphragm is welded flat and sealed to the stainless steel body. The quartz element is mounted in a sealed container attached to the converter body to enhance sensitivity. Typically, a screw-on cover or hose connector is used to introduce the pressure to be measured.

Applications/Examples of results
Removing the cover makes it particularly suitable for measuring dynamic pressure that fluctuates at high speeds. When both the cover and hose connector are attached, the frequency response is significantly reduced due to the Helmholtz resonance phenomenon. Quasi-static measurements for a few minutes are possible if conditions are met. - Dynamic and quasi-static pressure measurement 1. Investigation of the dynamic behavior of the air column in pipes within blowers and compressors 2. Pressure measurement in the carburetor of internal combustion engines 3. Pressure measurement in pneumatic control circuits and fluid engineering 4. Measurement of pressure pulses in automatic oil ignition devices 5. Measurement of sudden atmospheric pressure fluctuations (ultra-low frequency sound waves)
