Description
Technical field
The utility model relates to measures quasi-instrument instrument field, is specifically related to a kind of little power consumption multiparameter transmitter of doing measure control on differential pressure flowmeter.
Background technology
As shown in Figure 1, the use of traditional differential pressure flow transducer will be passed through a plurality of transmitters such as differential pressure transmitter, temperature transmitter, pressure unit, secondary instrument and form a metering system, and must external 24V power-supply system could work.Therefore, existing differential pressure flowmeter structure more complicated is not only installed the trouble effort, and is difficult to use under the occasion that external power supply much can not be provided; In addition, energy consumption was very big when existing differential pressure flow transducer used, and seemed incompatible with in the today of being becoming tight energy day, had very big necessity to make improvements.
The utility model content
The purpose of this utility model provides a kind of transmitter of simple in structure, integral multi-parameter, to realize the microminiaturization and the low power consuming of differential pressure flow transducer.
For reaching above-mentioned utility model purpose, a kind of little power consumption multiparameter transmitter of the utility model, comprise control circuit and secondary instrument, described control circuit links to each other with pre-amplification circuit, described pre-amplification circuit links to each other with sensor, described control circuit is connected with the battery management circuit is two-way with radio communication circuit respectively, and described battery management circuit links to each other with battery.
Further, described sensor comprises in temperature sensor, pressure transducer, the differential pressure pick-up at least two kinds.
Further, above-mentioned battery is a disposable battery.
The utlity model has easy to use, light and handy advantage easy to carry, whole apparatus structure is simple, and is quick for installation, simplified the use difficulty of differential pressure flowmeter, promoted the popularization and the use of differential pressure flowmeter.In addition, the design of little power consumption makes the utility model device save the energy in use, and environmental protection is made contributions for creating economical and environment-friendly society.
Description of drawings
Fig. 1 is the structural representation of existing multiparameter transmitter.
Fig. 2 is the structural representation of the little power consumption multiparameter of the utility model transmitter.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The little power consumption multiparameter of the utility model transmitter comprises control circuit and secondary instrument, control circuit links to each other with pre-amplification circuit, pre-amplification circuit links to each other with temperature sensor, pressure transducer, differential pressure pick-up, control circuit is connected with the battery management circuit is two-way with radio communication circuit respectively, and the battery management circuit links to each other with battery.The battery that uses in this device is disposable battery.The whole little power consumption designs of the circuit of this multiparameter transmitter, CPU adopts little power consumption process chip MSP430F437 of TI.Pre-amplification circuit adopts the instrument amplifier TL27L2 of little power consumption, the signal of differential pressure pick-up, pressure transducer, temperature sensor is handled amplified and deliver to CPU MSP430F437 and carry out computing.
As shown in Figure 2, little power consumption multiparameter transmitter is made up of transmitter 1, differential pressure pick-up 2, connecting line 3 and temperature and pressure sensor 4 in the present embodiment, be provided with the secondary instrument (not shown) in the transmitter 1, differential pressure pick-up 2, temperature and pressure sensor also are integrated and connected on transmitter 1, realized integratedly thus, use to have installed very convenient.
Though the utility model is illustrated hereinbefore according to preferred embodiment, this does not represent that scope of the present utility model is confined to above-mentioned structure, if by structure that claim of the present utility model covered all within protection domain.Those skilled in the art can be developed the equivalent substitution structure that at an easy rate after reading above-mentioned explanation, in following equalization variation and the modification of being done of spirit that does not break away from the utility model and scope, all should be covered by within the utility model claim.
