The utility model discloses setting up of protection casing makes solid adsorption thing or cladding thing reduce with the contact probability who measures the diaphragm, has guaranteed greatly that the measuring goes on smoothly, and has effectively avoided solid matter and measured the damage that the diaphragm contact caused, has prolonged the life who measures the diaphragm, simultaneously the utility model discloses from area clearance structure, it is very convenient to use.
Description
Technical field
This utility model relates to a kind of pressure transmitter, and the measuring diaphragm of a kind of improvement is difficult to the pressure transmitter being coated with by outer solid material.
Background technology
Pressure transmitter refers to be output as the pressure transducer of standard signal, it utilizes load cell (also referred to as measuring diaphragm), measuring circuit and process connector three part to be made, it is that one accepts pressure variations, after sensing and transducing, pressure variety is converted to by a certain percentage the instrument of standard output signals.The physical pressure parameters such as gas that load cell can be experienced by it, liquid are transformed into the signal of telecommunication of standard, measure, indicate and procedure regulation supplying the secondary meters such as indicator alarm, monitor, actuator.
Pressure transmitter has been widely used in the industrial system needing to monitor the physical descriptors such as pressure.By pressure transmitter, the medium in industrial system can be detected or measures, to realize the detection to industrial system state or measurement.But in the industries such as chemical industry, thermoelectricity, Living Water and metallurgy, sometimes in the face of the rough ambient environmental of a large amount of dusts or flue dust, or the complex situations that in liquid, solid dopant thing is more, and owing to the currently used flange seat not adding protection directly measures, measuring diaphragm will be coated with by the miscellaneous dirt of solid or solid dopant thing in a short period of time, inaccurate even cannot the proceeding of measurement result is caused to measure, the service life of pressure transmitter and the job schedule of measurement are had a strong impact on, so needing to improve prior art to solve this problem.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model provides a kind of pressure transmitter, solve the technical problem that existing measuring diaphragm is easily coated with by the miscellaneous dirt of solid or solid dopant thing, being smoothed out of measurement has been effectively ensured, has effectively extended its service life.
This utility model solves its technical problem and be the technical scheme is that a kind of pressure transmitter, including flange seat and the measuring diaphragm that is arranged on flange seat, characterized by further comprising the cylindrical protective cover of upper opening, the periphery of the bottom measuring diaphragm of described flange seat is provided with thread groove, the mode that described protective cover is threaded connection realizes firm connection between thread groove with flange seat, and the circumference side of protective cover is provided with some air-vents.
Preferably, a diameter of 0.5～1.5 millimeter of described air-vent, the thickness of the circumference side of described protective cover is 1～2 millimeter.
Preferably, described protective cover is stainless steel.
Preferably, described protective cover bottom surface extends outward outside circumference side 1～2 centimetre, and its bottom surface is preferably provided to dismountable bottom form；The circumference side of described protective cover is externally provided with cleaning post, cleaning column wall is provided with projection or hairbrush layer, being connected with connecting rod one end on the upside of cleaning post, the other end of connecting rod is connected through the through hole being arranged on flange seat with handle, and described connecting rod quantity is two and is symmetrical arranged.In the most severe external environment condition, the air-vent of protective cover is easy to blocked, thus affects measurement result, and arranging of cleaning post can carry out outside cleaning at any time to protective cover, is smoothed out so that measure.
Good effect of the present utility model: the setting of this utility model protective cover makes solid absorption thing or coating reduce with the contact probability of measuring diaphragm, greatly ensure that being smoothed out of measurement, and effectively prevent solid matter and contact the damage caused with measuring diaphragm, extend the service life of measuring diaphragm, this utility model carries cleaning structure simultaneously, extremely easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail.
With reference to Fig. 1, this utility model preferred embodiment provides a kind of pressure transmitter, including flange seat 1 and the measuring diaphragm 2 that is arranged on flange seat, characterized by further comprising the cylindrical protective cover 3 of upper opening, the periphery of the bottom measuring diaphragm 2 of described flange seat 1 is provided with thread groove, the mode that described protective cover 3 is threaded connection realizes firm connection between thread groove with flange seat 1, and the circumference side of protective cover 3 is provided with some air-vents 4.
A diameter of 0.8 millimeter of described air-vent, the thickness of the circumference side of described protective cover is 1.5 millimeters.
Described protective cover 3 is stainless steel.
Described protective cover 3 bottom surface extends outward outside circumference side 1 centimetre, and its bottom surface is arranged to dismountable bottom form；The circumference side of described protective cover 3 is externally provided with cleaning post 5, cleaning post 5 inwall is provided with projection or hairbrush layer, being connected with connecting rod 6 one end on the upside of cleaning post 5, the other end of connecting rod 6 is connected through the through hole 8 being arranged on flange seat with handle 7, and the quantity of described connecting rod 6 is two and is symmetrical arranged.In the most severe external environment condition, the air-vent of protective cover is easy to blocked, thus affects measurement result, and arranging of cleaning post can carry out outside cleaning at any time to protective cover, is smoothed out so that measure.
The setting of this utility model protective cover makes solid absorption thing or coating reduce with the contact probability of measuring diaphragm, greatly ensure that being smoothed out of measurement, and effectively prevent solid matter and contact the damage caused with measuring diaphragm, extend the service life of measuring diaphragm, this utility model carries cleaning structure simultaneously, extremely easy to use.
Above-described only preferred embodiment of the present utility model; it is it should be understood that; the explanation of above example is only intended to help to understand method of the present utility model and core concept thereof; it is not used to limit protection domain of the present utility model; all made within thought of the present utility model and principle any amendment, equivalent etc., within should be included in protection domain of the present utility model.
