The digital pressure gauge also can be provided with a 3-bit LED (light-emitting diode) digital displayer and an alarm indicating lamp, a ceramic pressure sensing element is arranged in the pressure gauge head, and a converted electric signal and a control signal of a control terminal are transmitted by virtue of a sensor. The digital pressure gauge can realize real-time display and has the characteristics of small digital error, high stability, second level of setting time, large numerical value of testing pressure value, small degree of influence by environment and medium temperature, and the like.

Description

Digital pressure gauge
Technical field
The utility model relates to a kind of measurement mechanism, the tensimeter that especially a kind of fluid of the import and export pipeline that relates to pump or gas pressure value show.
Background technology
Digital pressure gauge reflection digital error is big at present, poor stability; Do not have pressure value setting or setting-up time long, be level second; Test pressure value scope is little, can not detect negative pressure value; Measuring accuracy is poor; Be subjected to environment and medium temperature influence degree big.
Therefore, need to solve measuring accuracy deficiency that existing tensimeter exists, can not the pressure measurement negative pressure, technical matters such as setting-up time is long, especially show to run into this class problem through regular meeting at the fluid of the import and export pipeline of pump or gas pressure value.
The utility model content
In order to improve the technical indicator of conventional digital pressure gauge, make the force value signal can realize instant dynamic transmission, can realize simultaneously detection of negative pressure, further improve measuring accuracy, the utility model provides new technical solution, force value can be converted to the output of electric current or voltage signal, because the marking current value is small, can also be useful in the occasion of requirement of explosion proof.
Digital pressure gauge of the present utility model comprises pressure gauge outfit, sealing socket, sensor interface, digitizing tablet, and this pressure gauge outfit connects sealing socket, and digitizing tablet is connected on the pressure gauge outfit, and sensor interface links to each other with the pressure gauge outfit.
Further, digitizing tablet is provided with 3 LED digital indicators.
Further, be provided with numeral in the digital watch display and show the dynamic response pipe, described numeral shows that the interior pressure medium value variation range of pipeline of dynamic response pipe is-1bar to 20bar.
Further, sensor interface is made as M12 * 1,5 hole plug, can connect the distinct interface of sensor according to actual needs, measures curtage.Sensor interface can be selected according to actual needs, is respectively a, b, c, d, e port, during use, selects a end, and according to actual needs, selects any end of b, c, d, e, and during actual the use, a, b, c, d, e port are set at different colors respectively.
Further, digitizing tablet is provided with alarm lamp, can setup pressure value, and beyond the value range of setting, the output of then reporting to the police.
Further, the pressure gauge outfit is provided with the rotation angle of 330 degree.
Further, be provided with the ceramic pressure sensitive element in the pressure gauge outfit.
Further, sealing socket is a stainless steel seat.
Adopt above structure, compared with prior art, the utility model can be realized real-time demonstration, and digital error is little, and stability is high; Setting-up time is a second level; Test pressure value numerical value is big, is subjected to characteristics such as environment and medium temperature influence degree are little.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Digital pressure gauge as figure, comprise pressure gauge outfit 1, sealing socket 2, sensor interface 3, digitizing tablet 4, be fixed on above the pipeline by sealing socket 2, and the sealing gasket 7 of the O type circle of sealing socket 2 inside and management interface sealing, medium carries out the pressure inspection by pressure gauge outfit 1, pressure gauge outfit 1 inner dried ceramic measurement component, this measurement component is a pressure-sensing device, convert the pressure medium value to electric current or voltage signal, the electric current or the voltage signal transmission of corresponding pressure value be can carry out by sensor interface 3 simultaneously, electric current and voltage signal converted to; Be converted to digital signal or simulating signal through internal circuit, by sensor interface 3 outputs; Carry out numeral by digital indicator 6 simultaneously on digitizing tablet 4 and show, simultaneously, pressure indicator light shows respective color.
Confirm that through test the technical parameter that the utility model can be realized is as follows:
Accuracy rating :≤± 0.5% FS @25 ℃;
Setting-up time: 200ms;
Medium Measurement temperature :-25-100 ℃
Temperature pattern :≤± 0.03%(zero point); ≤ ± 0.02%(continuity point)
Long-time stability :≤± 0.5% every year
Degree of protection: IP67
After fixing, the pressure gauge outfit can 330 angles be rotated, and fixing.
The utility model has improved the degree of accuracy of conventional digital pressure gauge, realizes the mensuration of negative pressure value, can measure in real time simultaneously, and reaction velocity is fast, adaptation in extensive range.
