Core Tip: The precision digital meter is an instrument that measures precision pressure, and precision digital meters are high precision pressure measurement and calibration instruments for microcontrollers. The precision digital table is suitable for use in the field and in the laboratory. Precision digital table in use, the user for the precision digital table knowledge is needed to master.
   The precision digital meter is an instrument that measures precision pressure, and precision digital meters are high precision pressure measurement and calibration instruments for microcontrollers. The precision digital table is suitable for use in the field and in the laboratory. Precision digital table in use, the user for the precision digital table knowledge is needed to master. One of the most important is the principle, and only understand the principle of precision digital table users can understand and use the precision digital table.

Based on the silicon sapphire sensor sensor and the new digital pressure gauge spread, the instrument overcomes the shortcomings of the previous generation of precision digital pressure gauges, is a new generation of digital pressure gauges with the following characteristics: Long life sensor, signal stability, good sealing To prevent leakage, High precision and wide temperature range (measured to high temperature 300 ℃), the temperature drift is small, our products -30 ℃? 70 ℃ range can be a normal working environment, and the maximum drift of less than 0.3%.

From a global perspective, the diffusion of silicon sensors is widely used in petroleum, chemical, power, aerospace, automotive and other important places; and ceramic piezoresistive sensors are limited only in civilian areas; the spread is silicon sensor ceramic piezoresistive sensor 3 To 10 times. The instrumental sensor plays a central role in its choice of life instruments, accuracy, reliability and safety options. For the safe, reliable and accurate operation of the website, please choose carefully.

Signal processing circuit processing pressure sensor, signal processing circuit mainly by the industry's most advanced low-power processor, high-performance amplifier and power management chip; instrument software design reasonable, in the sensor calibration and temperature of the nonlinear compensation beautifully in the high efficiency And ultra-low power consumption at the same time. In our actual test signal circuit board at -30 ℃? The overall drift process in the range of 75 ° C is 0.089% generally seen in the precision section.
