Pressure sensor selection common terms: accuracy at a certain temperature (23 ° C), when added to the zero pressure and the rated pressure, with the full-scale output current value of the removal of specified value deviates (4mA, 20mA) values ??obtained value. Units with% FS. Linear analog output to detect pressure changes linearly filter pressure annunciator offer, but compared with the ideal line deviations. As a percentage of the full-scale value to represent the values ??for this bias is called linear. Hysteresis (linear) with a zero voltage and the rated voltage when the output current (or voltage) between the value of the ideal straight line is drawn, the current (or voltage) and the ideal current (or voltage) as the difference between the value of seeking out error, then obtained When the pressure rise and fall time of the error value. With the full scale current (or voltage) value removing the maximum absolute value of the difference between the obtained value is the hysteresis. Units with% FS. Hysteresis with full-scale removal of the output value of the pressure point of the pressure difference between ON OFF resulting point pressure of both the hysteresis. Refers to non-corrosive gases contained in the air substances (nitrogen, carbon dioxide, etc.) with an inert gas (argon, neon, etc.). It consists of the internal structure of the material, metal strain wire or strain foil insulation sheet and lead other parts of the base composition. According to different purposes, the resistance strain gauges can be designed by the designer, but it should be noted that the range resistance: resistance is too small, the required drive current is too large, while the fever itself causes strain gage temperature is too high different environments, so that the change in resistance strain gauge is too big, obvious output zero drift filter pressure signal, a zero circuit too complicated. The resistance is too large, the impedance is too high, poor resistance to external electromagnetic interference. Europe in general are tens to tens of thousands of euro.
