Differential Pressure Sensor

This paper study an method of extension the range of gas- electric measurement. Using the effection of the high speed air flowing into the throttle orifice make out an wide rang and not be affected by the fluctuation of the gas source pressure gas-electrical measurement .The measured value of using the differential pressure sensor is greater than the value of the gas source pressure, effectively increase the effective rang. C8051F350 microcontroller with built-in 24-bit resolution AD converter, 18b20 temperature sensor, RS485 bus, and industrial computer are used to make of measuring and controlling system .

Dynamic Weighing

In order to satisfy the need for vehicle dynamic weighing in over-loading detection, the software and hardware of system are designed. The system uses CS5530, which can achieve 24-bit performance, as its AD converter. Apply with the technology of the radio frequency(RF) and embedded operate system, the system can collect, send, display, store and print the information of vehicles in time.

Simulation Results

In this paper we proposed an approach for obtaining optimal stable modulator coefficients, which satisfy both SNR and stable input limit requirements. The empirical (3rd to 5th order) stable input limit formula is presented. Modulator examples are presented to demonstrate the usage of proposed method. The simulation results show that nearly 1-bit (6 dB) resolution is improved with the proposed method. The op-amp dc-offset influence on modulator performance is also discussed.
