The measuring principle of the Dell Precision M2300 battery pressure transmitter is shown in Figure 3. The measurement principle is: the laptop battery process pressure and reference pressure acting on the ends of the integrated silicon pressure-sensitive components, differential pressure so that the silicon deformation (displacement is very small, only the μm level) so that the silicon semiconductor technology system into the whole dynamic of the Wheatstone bridge output is proportional to the pressure in the external current source is driven by Dell Precision M65 battery the mV level voltage signal. Strong silicon material excellent linearity of the output signal and variation indicators are very high.
Work, pressure transmitter, the measured physical quantity to convert the mV level voltage signal, the laptop battery and sent to a high magnification and offset temperature drift of the differential amplifier. Amplified signal is converted by the voltage and current transformation into a corresponding current signal after the nonlinear correction, and finally a standard current and voltage signals into a linear relationship Dell Precison M90 battery with the input pressure.Pressure transmitter pressure measurement range can be divided into general pressure transmitter (0.001MPa ~ 20MP3) and micro-differential pressure transmitter (0 ~ 30kPa) two kinds.
The proportion of the general magnetic float is less than 0.5, can drift above the liquid level and move up and down along the measuring catheter. Catheter equipped with measurement devices, it can be outside the magnetic effect will convert the measured level signal proportional to the level change of resistance of the signal, and electronic unit is converted into 4 ~ 20mA standard signal output. The transmitter module circuit, acid, Dell PT434 battery moisture, shock, anti-corrosion and other advantages, within the laptop battery circuit containing a constant-current feedback circuit and internal protection circuitry.
