The pressure sensor shows negative numbers. What's the matter?
This is a special negative pressure sensor. It has the following characteristics:The sensitivity coefficient of the piezoresistive pressure sensor is 50-100 times larger than that of the metal strain sensor. Sometimes, the output of the piezoresistive pressure sensor can be measured directly without the amplifier.Because it is processed by integrated circuit technology, it is small in structure and light in weight.The pressure resolution is high, it can detect the micro pressure as small as the blood pressure.The frequency response is good, it can measure the pulsating pressure of tens of khz.It is made of semiconductor material silicon. Because of the Li Min component and detecting element of the sensor made on the same silicon chip, it is reliable, comprehensive, high precision and long service lifeThis performance is relatively stable, design and production of specialized OEM customersToday Germany imported silicon sensor has excellent corrosion resistance, impact resistance, and overload, anti vibration, anti wear performanceThis wide range of working temperature, high precision measurement, good long-term stabilityA design and production of all regulations to ensure that the products of advanced, practical and quality stability
If the value is too large and the display program is not very strict, negative values may be displayed. Is a manifestation of overflow.The problem may lie in the sensor, or in the display section.
The force sensor displays negative numbers because the positive and negative of the pressure sensor are reversed.The positive and negative of the pressure sensor will reverse and a negative number will appear.Solution: change the positive and negative, that is, the two lines of access to exchange position.
