In the utility model preferred embodiments, described multiplex (MUX) detection system can comprise pressure transmitter.
In the utility model preferred embodiments, described dividing plate is also provided with left vertical-shaped groove and right vertical-shaped groove, the vertical-shaped groove in a described left side and right vertical-shaped groove and the machine-shaping of dividing plate one.
In the utility model preferred embodiments, the vertical-shaped groove in a described left side and right vertical-shaped groove inner side are provided with guiding groove.
In the utility model preferred embodiments, described apopore is 60mm apart from water tank bottom plate, and inside is provided with flowrate control valve.
In the utility model preferred embodiments, the range of described straight steel ruler is 0 ~ 1000mm.
The beneficial effects of the utility model are: a kind of pressure transducer self-checking unit of the utility model, multiple pressure transducer can be detected, make instrument self checking work convenient and swift, significantly improve instrument testing efficiency, avoid because the damage that instrument causes instrument is carried in censorship work back and forth simultaneously, reduce damage of product, ensure that the security of pressure product.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of pressure transducer self-checking unit one of the present utility model preferred embodiment;
Fig. 2 is the diaphragm structure schematic diagram of Fig. 1;
Fig. 3 is the A-A cut-open view of Fig. 2.
Embodiment
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 3, the utility model embodiment comprises:
A kind of pressure transducer self-checking unit, comprise verification water tank 1, straight steel ruler 2, dividing plate 3 and multifunctional examining examining system 4, described dividing plate 3 is vertically set in the middle of verification water tank 1, described straight steel ruler 2 is fixed on dividing plate 3, the first mounting hole 3-1 is disposed with from the bottom up in the middle of described dividing plate 3, second mounting hole 3-2 and the 3rd mounting hole 3-3, described multifunctional examining examining system 4 is arranged on outside verification water tank 1, is provided with apopore 5 bottom described verification water tank 1.
In above-mentioned, detected pressure transducer can be fixedly mounted in the first mounting hole 3-1, the second mounting hole 3-2 or the 3rd mounting hole 3-3, can place multiple detected product simultaneously.
Further, described multiplex (MUX) detection system 4 can comprise pressure transmitter (not shown), and pressure transmits gas and is connected with detected product.
Further, described dividing plate 3 is also provided with left vertical-shaped groove 3-4 and right vertical-shaped 3-5, a described left side vertical-shaped groove 3-4 and right vertical-shaped groove 3-5 and the machine-shaping of dividing plate 3 one, left vertical-shaped 3-4 and right vertical-shaped groove 3-5 inner side are provided with guiding groove 3-6, can by straight steel ruler 2 in guiding groove 3-6 through verification water tank 1 bottom, make the zero graduation of straight steel ruler 2 and check bottom water tank 1 in same plane, the range of straight steel ruler is 0 ~ 1000mm
