parentheses for dividing number as the user needs to make a special order processing.2, table 2 measurement range specifications listed are for reference only, the user can indicate with orders as required.3, transmitter remote pressure gauge, when you order it should indicate the type of input signal range and display range range, unit symbols.Various physical being measured by sensor or transducer is converted into voltage, resistance, power flow input, the input circuit transformation into a unified mV signal, send amplifier amplification, simultaneously linearization is measured and the signal into a linear relationship, and then the output circuit output three road.All the way to send A/D analog-to-digital converter.Converter with decoding drive, automatic zero, polarity display circuit, such as direct drive LED by digital display measured.All the way to send V/I conversion and power amplification, constant current output.Another way to send comparison circuit compared with set values by executing circuit in the form of contact signal to adjust the output. |
