Abstract
The utility model discloses a pressure transmitter. The pressure transmitter comprises a joint member. The bottom of the joint member is electrically connected with an insulating membrane which is formed by multiple membranes wrapped in insulating material. The bottom of the insulating membrane is fixed to a transmitter housing. A wire board is arranged in the transmitter housing, and flexible cables are vertically disposed on the wire board and electrically connected with the wire board. The flexible cables pass through the wire board to be electrically connected with a ceramic pedestal. The ceramic pedestal is of a cavity structure, and a region strain zone is disposed in the cavity and is electrically connected with the ceramic pedestal via a lead. A bulkhead is disposed at the bottom of the transmitter housing and the bottom of the bulkhead is connected with a blind hole. The blind hole and the bulkhead are connected via a sealing device. A cable coil is arranged in the blind hole. Through application of the pressure transmitter, pressure of to-be-measured fluid can be measured when the fluid passes through the ceramic pedestal, and the ceramic pedestal can be thoroughly cleaned in a convenient manner. Meanwhile, the pressure transmitter is high in interference resistance, simple in packing and high in work efficiency.
Description
Technical field
The utility model relates to a kind of change and send device, particularly a kind of pressure transmitter device.
Background technology
Pressure unit is a kind of conventional sensor, and it is widely used in various of a great variety, and pressure unit is mainly used in measuring liquid level, density and the pressure of liquid, gas or steam, then pressure signal is transformed into DC signal output.But pressure unit great majority adopt split-type design now, this transmitter cannot be accomplished current-output type, because the heat of High-current output is not easy to distribute, and also have kind of the pressure unit based on the sensitive element such as ceramic sensor element or diffusion silicon pressure sensor to encapsulate the main version that adopts one, use a screw element that sensitive element is pressed in to inner chamber downside, between sensitive element and inner chamber, use O-ring seal to seal, adopt this type of pressure transducer, still exist certain deficiency, hydrodynamic pressure can better do not detected, and disassembly, cleaning inconvenience.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provide one conveniently thoroughly to clean base of ceramic, in the time detecting, antijamming capability is strong simultaneously, and encapsulation is succinct, the pressure transmitter device that work efficiency is high.
To achieve these goals, the technical solution adopted in the utility model is such: pressure transmitter device of the present utility model, comprise adapter piece, adapter piece bottom is electrically connected with insulation diaphragm, insulation diaphragm is made up of the diaphragm of several outsourcing insulating material, insulation diaphragm bottom is fixed on transmitter shell, wired plate is installed in transmitter shell, winding displacement is vertically installed on line plate, between winding displacement and line plate, be electrically connected, winding displacement is electrically connected with a base of ceramic through line plate, base of ceramic is cavity structure, in its cavity, be provided with areal strain district, areal strain district is electrically connected with base of ceramic by wire, transmitter outer casing bottom is provided with a plug, plug bottom is connected in a blind hole, between blind hole and plug, be connected by packoff, in blind hole, be provided with cable coil, cable coil is electrically connected with areal strain district by built-in circuit.
Further, as a kind of concrete version, in transmitter shell described in the utility model, be also filled with epoxy sealing electrical equipment.
Further, as a kind of concrete version, between plug described in the utility model and blind hole, adopt riveted structure.
Compared with prior art, the utility model has the advantage of: when this pressure transmitter device passes through base of ceramic in detected fluid, can record the pressure of fluid, and can conveniently thoroughly clean base of ceramic, in the time detecting, antijamming capability is strong simultaneously, and encapsulation is succinct, and work efficiency is high.
