The output characteristics of pressure sensor

Pressure sensor features:

1 can realize self-diagnosis function, can timely and accurately on the part of the failure of locking, fault state recognition quickly, to solve some questions through hardware cannot come true.

2 signal output form and interface to choose more diverse, more improved communication distance.

3 sensor sensitivity and accuracy of measurement is improved at the same time, for a weak signal measurement, the calibration and compensation of all sorts of signals can be realized, the measurement data can be according to the need for storage.

4 data measuring stability and possibilities for promotion, reduce the pressure of external environment on the sensor output interference, measurement can be selectively.

5 sensor range and function have been further extended, can realize the basic parameters and specific measurements, meet the needs of different occasions.

the working principle of pressure sensor, pressure sensor is a device convert non-electric quantity into electrical signals, and testing instrument under the condition of analog electronic technology, is typically include sensors, testing point sampling equipment and amplifier ( Anti-interference processing and signal transmission) Power supply and the field display section (and, of course, Optional) , electrical signals for continuous and discrete quantity is two, actually can also be divided into analog and switch quantity, pulse volume, analog signal transmission adopts unified signal ( 4 - 20 madc, etc. ) 。

, in the process of digital change detection instrument is bigger, go through several stages, and more recently by ASIC application-specific integrated circuit, and the sensors, and microprocessor and network interface encapsulation in a device, complete information acquisition, processing, transmission, storage, and other functions. Often called the instrument measuring transducer in the automation instrument, such as temperature transmitter, pressure transmitter, etc.
