Abstract

The utility model provides a tester of a temperature transmitter. The tester comprises a display instrument and multiple input ports, wherein the display instrument can be used for displaying in the form of a temperature, voltage or current signal, the multiple input ports comprise power input ports, range selection ports and COM (Component Object Model) ports, wherein the range selection ports are connected with the COM ports in an instrument through multiple high-precision resistors, and the power input ports, the range selection ports and the COM ports adopt insulation protecting jackets in different colors outside the instrument. The tester, provided by the utility model, has the advantages of various data display manners, and more accurate and effective measurement.

Description

A kind of temperature transmitter tester

Technical field

The utility model relates to the electronic surveying field, specially refers to a kind of temperature transmitter tester.

Background technology

Conventional temperature transmitter tester all is to adopt testing tool tests such as voltage table or reometer, more single easy generation error result.

Summary of the invention

In order to overcome the defective of prior art, the utility model provides following technical scheme:

A kind of temperature transmitter tester comprises Displaying Meter, some input ports; Said Displaying Meter shows that with the form of temperature, voltage or current signal said some input ports comprise the power supply input port, measurement range selection port and COM port; Said measurement range selection port links to each other with some precision resisters in instrument internal with said COM port; Said power supply input port, the measurement range selection port, COM port is at the outside insulation protective jacket that adopts different colours of instrument.

The beneficial effect that the utility model brought is: display mode is various, is convenient to comparing data, and measurement result is more accurate.

Description of drawings

Fig. 1 is the utility model panel synoptic diagram;

Fig. 2 is the utility model workflow diagram.

Label among the figure:

1, voltage Displaying Meter; 2, electric current Displaying Meter; 3, temperature display meter.

Embodiment

Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.

See Fig. 1, Fig. 2:

A kind of temperature transmitter tester; Comprise Displaying Meter, some input ports, said Displaying Meter can be voltage Displaying Meter 1 or electric current Displaying Meter 2 or temperature display meter 3; Said some input ports comprise the power supply input port; Measurement range selection port and COM port, said measurement range selection port links to each other with some precision resisters in instrument internal with said COM port, respectively zero point, 25% measurement point, 50% measurement point, 75% measurement point, the 100% measurement point resistance of corresponding range.Said power supply input port, the measurement range selection port, COM port is at the outside insulation protective jacket that adopts different colours of instrument, and is safer during surveying work.

During work; The power supply signal access point of temperature transmitter is inserted in the supply hub of tester; The signal common port of the input of temperature transmitter is linked to each other with the COM port of tester; Temperature transmitter another one input end inserts the measurement range selection port corresponding to the zero point of temperature transmitter measurement range, 25% measurement point, 50% measurement point, 75% measurement point, 100% measurement point successively; And note the numerical value of corresponding test Displaying Meter; The standard value that itself and this temperature transmitter should be exported compares, and each measured value has one to exceed deviation range promptly to be judged to be measured temperature transmitter defective, and each measured value all is qualified in deviation range.

The various demonstration that is not limited to a certain mode of the utility model display mode, test data is convenient to comparison, and measurement result is precise and high efficiency more.Solve the defective that single test possibly bring error result.

The above; Be merely the embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the utility model disclosed, and variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.

Claims
