The utility model adopts pressure transducer to make transmitter have the characteristic of weighing instrument; Power module adopts Width funtion adjustment chip SX3002, reduces temperature drift, makes transmitter setting range wide; Adopt DA conversion module in conjunction with precision current output module and accurate voltage output module, antijamming capability is strengthened, the conditions for equipment uses such as the frequency converter of industrial complexity, PLC can be applicable to; Adopt communication module to be connected with PC, make whole adjustment all on a PC interface, do not need same instrument equally to need to check and the content understanding instructions can operate, simple to operate, click five or six buttons at most.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of this digital observing and controlling transmitter.
Embodiment
As shown in Figure 1, a kind of digital observing and controlling transmitter, comprise housing 1, CPU control module 2 is provided with in described housing 1, force snesor module 3, AD sampling module 4, DA conversion module 5, alarm module 6, communication module 7, key-press module 8, precision current output module 9 and accurate voltage output module 10, the input end of described CPU control module 2 is connected with the output terminal of AD sampling module 4, its output terminal connects DA conversion module 5, alarm module 6, communication module 7, the input end of key-press module 8, the input end of described AD sampling module 4 connects the output terminal of described force snesor module 3, the output terminal of described DA conversion module 5 connects the input end of described precision current output module 9 and accurate voltage output module 10 respectively, also comprise power module 11, described power module 11 adopts Width funtion to adjust chip SX3002, to CPU control module 2 and force snesor mould 3 pieces power supply, also comprise the PC display module 12 be positioned at outside housing, the output terminal of the input end connecting communication module of described PC display module.
Described power module 11 adopts Width funtion to adjust chip SX3002, to CPU control module and force snesor module for power supply, coordinate a wire-wound inductor, two resistance proportionings, a diode and two electric capacity can realize 10 ~ 40V Width funtion to power input, 6 ~ 15V voltage stabilizing exports and makes circuit reduce by more than 20% than general analog transmitter in power consumption.
