Description
Technical field
The present invention relates to a kind of checkout equipment, be specifically related to a kind of multifunctional all transmitter.
Technical background
Transmitter is the device that the information such as physical quantity, chemical quantity of impression is converted according to certain rules to the normalized signal of being convenient to measurement and transmission, is the ingredient of unit aggregated instrument.Transmitter also can be described as a kind of sensor that is output as normalized signal.Most of transmitters be the series connection of power supply and output current signal, two two-wire system transformers that wire transmits simultaneously.
At present the function ratio of transmitter is more single, divide by function have temperature transmitter, pressure unit, flow velocity transmitter, liquid transducer, ultrasonic transducer etc., can only detect corresponding project, as temperature, pressure, flow velocity etc.Although also there has been integrative temperature transmitter, by together with the organic integration of temperature-sensing element (thermal resistance or thermopair) and signal conversion amplifying unit, temperature-sensing element temperature influence has a resistance or electromotive force effect, produce a differential voltage signal through conversion, this signal amplifies through amplifier, through voltage, current transformation, export the signal such as current signal or other 0-5V/0-10V of the 4-20mA corresponding with range again.The temperature of liquid, steam and other gas medium or solid surface within the scope of be used to measure in various technological processs-200-1600 ℃.It conventionally and Displaying Meter, recorder and various control system support the use.
But along with the development of automatic control technology, substantially all need pressure, temperature, flow velocity, liquid level etc. to be detected, controlled simultaneously.As the air inlet air pressure at different levels of multistage compressor and temperature, air pressure and the temperature etc. of giving vent to anger all need to detect simultaneously, if serviceability temperature transmitter, pressure unit carry out collection signal respectively, one need to lead interior porous at the container of installing or pipe, many arranging signals transmit cable and associated conduit, cause and install and connect up very inconveniently, cost is also higher.The more important thing is temperature transmitter, pressure unit, what gather is not the signal of same place, thereby cause deviation of signal large, collection signal is inaccurate etc.
In addition, SO2, NOx in measurement flue gas, C0, when the gas concentration such as 02, be subject to the impact of the interior flue-gas temperature of flue and pressure, the result of measuring can not reflect actual gas discharging situation, also needs the result of measurement to be scaled the gas discharging concentration under the status of criterion, at this moment just has the value of weighing concentration of emission height with reference to comparison.And all use the parameter such as flue-gas temperature, flue static pressure in converting and calculating harmful gas emission.Therefore need to measure temperature, pressure, flow velocity of flue gas etc. simultaneously, need to use temperature transmitter, pressure unit and flow velocity transmitter simultaneously, if carry out independent measurement with these three kinds of transmitters respectively, cause that I&M inconvenience, volume are large and cost is high.
Summary of the invention
The present invention is directed to problems of the prior art, provide that a kind of volume is little, I&M multifunctional all transmitter easily, gathered the function of temperature transmitter, pressure unit, flow velocity transmitter, fluid level transmitter and ultrasonic transducer.
In order to achieve the above object, the present invention realizes by following technical proposal:
A kind of multifunctional all transmitter, comprises electronics chamber and terminal cavities, and described electronics is provided with amplifying circuit and solenoid valve in chamber, and described amplifying circuit is electrically connected with controller; In described terminal cavities, be provided with detecting element, the input end of described detecting element is electrically connected with described solenoid valve, its output terminal is connected with described amplifying circuit.
The preferred version of such scheme is that described detecting element is temperature sensor, pressure transducer, flow sensor, liquid sensor and ultrasonic sensor.
The output terminal of described controller is connected with communication module by A/D modular converter.
Described transmitter shell is provided with display screen, and the output terminal of described controller is electrically connected with display screen.
Described transmitter shell is provided with button, and described button is electrically connected with described solenoid valve.
The input end of described controller is connected with power supply.
The present invention is merged together into the most frequently used temperature sensor, pressure transducer, flow sensor, liquid sensor and ultrasonic sensor the transmitter of a multifunctional all, has that volume is little, a compact conformation, feature easy to use.Change the pattern that the past installs each sensor or transmitter respectively, overcome transmission error, improved the accuracy of Temperature Measure Control.Also can reduce a large amount of installation workload, reduce labour cost and use cost.In addition, there is multifunctionality and practicality, at the same time or separately detected temperatures, pressure, flow velocity, liquid and ultrasound wave.
The present invention is by the selection of button, connects the circuit of respective electrical magnet valve and its corresponding detecting element, controls each sensor and carries out the while or separately measure.The data that detect are after amplifying circuit amplifies, then via controller carries out Treatment Analysis and be presented on display screen, or are transferred to by communication module on the server of administrative center.The signal that simultaneously the present invention collects, after signal amplification circuit amplifies and processes, makes that signal is more clear, to measure numerical value more accurate.
