Digital display pressure measuring circuit diagram

The figure illustrates a digital display pressure measuring circuit diagram. The circuit operates with an additional voltage of approximately 12.8V and draws a current of 30mA. Under maximum gain conditions, the input voltage range is 0.8mV. The zero adjustment range is ±1mV/V, and the displayed value ranges from 0 to 1999. The zero shift is 2µV/°C, and the additional voltage shift is 0.005%.

This digital display pressure measuring circuit is designed to accurately measure and display pressure values through a digital interface. The circuit utilizes an analog-to-digital converter (ADC) to translate the analog input signal, which represents pressure, into a digital format that can be displayed on a digital readout.

The power supply for this circuit is specified at 12.8V, which is essential for the operation of the ADC and other electronic components. The current consumption of 30mA indicates a low-power design, suitable for battery-operated or energy-efficient applications.

The input voltage range of 0.8mV signifies that the circuit is capable of detecting very low pressure changes, making it suitable for high-precision applications. The maximum gain setting enhances the sensitivity of the circuit, allowing it to respond to minute variations in pressure.

The zero adjustment range of ±1mV/V provides flexibility in calibrating the circuit to account for any offsets that may occur during operation, ensuring that the displayed values are accurate. The display can show values from 0 to 1999, accommodating a wide range of pressure measurements.

Additionally, the zero shift specification of 2µV/°C indicates the temperature stability of the circuit, which is critical in applications where temperature variations can affect pressure readings. The additional voltage shift of 0.005% ensures that the circuit maintains its accuracy over time, further enhancing the reliability of the measurements.

This circuit can be integrated into various applications, including industrial pressure monitoring systems, laboratory equipment, and portable pressure measurement devices, where precision and reliability are paramount. Proper implementation of this circuit will require careful consideration of component selection, layout design, and calibration procedures to achieve optimal performance.The figure is a digital display pressure measuring circuit diagram.
