Abstract
The utility model provides an electromechanical integrated pressure transducer. The two ends of the main casing of a transducer are respectively provided with an electrical measuring pressure sensitive element and a mechanical pressure gauge which is extended by a capillary pipe to be connected in a back casing extended. The utility model has the advantages of electrical measuring and direct measuring simultaneously. When the electrical measuring transducer or the power supply fails, operators still can read the pressure data on measuring site.
Description
The utility model relates to a kind of pressure detecting element, belongs to pressure transducer.
Existing various pressure transducers all adopt the pressure unit mode of electric signal output or the indication of charged table, when sensor flexible member, sensitive element or cum rights break down or power the generation fault, can't judge the pressure state of measurement point, therefore need mechanical pressure gauge be installed at same point position in some application scenarios, make troubles to O﹠M.
The purpose of this utility model is will provide a kind of to be output as the master with electric signal, the pressure sensor structure that has simultaneously mechanical pressure indication gauge outfit, electromechanical integration again, by shell, pipe connect chew, sensitive element and garden arc or stranded tubes structure Bourdon pressure gauge etc. form
The utility model is achieved in that to be connected with electrical measurement pressure-sensing device assembly at pressure transducer main shell two ends respectively and to extend through kapillary and is connected to the mechanical pressure gauge assembly of band protective cover back casing, the former produces electric signal output, and the latter then directly demonstrates tested pressure value with pointer.
The utility model has the advantages that: have sensor electrical measurement precision height simultaneously concurrently, be convenient to that the transmission of remote signal and tensimeter are on-the-spotly directly surveyed intuitively, characteristics easily, when electrical measurement was partly broken down, the field staff still can directly obtain pressure data in measurement point.
Describe below in conjunction with the structure and the enforcement of accompanying drawing utility model.
Fig. 1 is an electromechanical integration pressure transducer wiring layout.
Fig. 2 is a top view.
With reference to accompanying drawing, 1 is electric signal pressure sensor output sensitive part, can be strain, pressure drag, electric capacity, piezoelectricity, inductance or potentiometer-type, 4 is the sensor circuit part, chew the machinery indication pressure measurement kapillary 2 that pressure guiding pipe 3 draws and be directed to arc Bourdon tube 6 in the sensor back casing 5 from connecing, the pressure effect is upheld drive pointer 7 down and show measured pressure value on index dial 8, and 9 is explosion-proof transparent windows, and 10 is electric signal output cable socket.
Claims (2)
1, a kind of electromechanical integration pressure transducer, by shell, pipe connect chew, sensitive element and Bourdon pressure gauge etc. form, it is characterized in that: sensor main shell [3] two ends are connected with electrical measurement pressure-sensing device [1] respectively and extend through kapillary [2] and are connected to mechanical pressure gauge [6] in the back casing [5].
2, pressure transducer according to claim 1 is characterized in that: Bourdon tube ［ 6 ］ can be garden arc or stranded tubes structure.
