Abstract

The utility model discloses a novel capacitance pressure transmitter, which belongs to a detection instrument in an electric product. The novel capacitance pressure transmitter comprises a shell, wherein, a sensor core body is arranged in the shell; the other end of the shell is connected with a procedure junction; a gasket is padded among the shell, the procedure junction and the sensor core body; the shell and the procedure junction are connected and fixed with each other through a hollow-head screw. By adoption the novel capacitance pressure transmitter, the problems of material wasting and assembly difficulty of the prior capacitance pressure difference and pressure transmitter are solved, and also the shortcomings of lacking capability of a diffusion silicon sensor or a dry capacitance sensor in the prior art are solved. Additionally, the novel capacitance pressure transmitter is of simple structure, convenient assembly and stable and reliable operation, and is of the novel capacitance pressure transmitter.

Description

A kind of novel capacitance pressure transmitter
Technical field
The utility model relates to the detecting instrument in the electric equipment products, a kind of specifically novel capacitance pressure transmitter.
Background technology
Capacitive pressure, differential pressure transmitter have multiple pattern, can be used for the measurement occasion of differential pressure, flow, gauge pressure, absolute pressure, vacuum tightness, liquid level and proportion.The structure of capacitance differential pressure and pressure unit is that differential pressure and pressure are general in the prior art, though this structure has unitarity, be applied in pressure applications separately, just the comparison waste material that shows, when requiring direct piping erection, then have certain difficulty simultaneously.
Requiring the pressure unit of direct piping erection at present, mainly is to adopt diffuse si sensor or dry type capacitive transducer, all is not so good as capacitance type sensor but these two kinds of sensors all have range ability, range ratio, anti-overload ability.
Show from the interrelated data retrieval that comprises Chinese patent, have not yet to see the directly relevant report of the capacitance pressure transmitter of piping erection.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of directly capacitance pressure transmitter of piping erection.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of novel capacitance pressure transmitter is characterized in that: a shell is arranged, sensor core is installed in the shell, the other end of shell is connected with the process joint; Be lined with O-ring seal between shell, process joint and the sensor core; Shell and process joint are connected and fixed by socket head cap screw.
The beneficial effects of the utility model are: because the utility model is with the structure of capacitance pressure transmitter according to pipeline, be designed to a kind of pressure unit of direct piping erection, both overcome the waste of material of former capacitance differential pressure and pressure unit and difficulty had been installed, solved the defective of the scarce capacity of prior art employing diffuse si sensor or dry type capacitive transducer again.Simultaneously, the utility model is simple in structure, and is easy for installation, and working stability is reliable, is a kind of novel capacitance pressure transmitter.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the utility model topology view.
1 shell among Fig. 1,2 sensor cores, 3 O-ring seals, 4 socket head cap screws, 5 process joints.
Embodiment
Embodiment 1:
See also Fig. 1, a shell 1 is arranged, sensor core 2 is installed in the shell 1, the other end of shell 1 is connected with process joint 5; Be lined with O-ring seal 3 between shell 1, process joint 5 and the sensor core 2; Shell 1 is connected and fixed by socket head cap screw 4 with process joint 5.
