The purpose is to overcome the technology problems that in the prior weighing sensor, the installation and usage are inconvenient, the bearing area is too small, the detection is unstable when a large force value is tested, and the weighing precision is influenced. The purpose is also to provide the center hole type weighing sensor, wherein the structure is simple, the installation and usage are convenient, the stability is enhanced by increasing the bearing area, and further the weighing precision is enhanced. The center hole type weighing sensor includes an elastomer, foil gauges, a sleeve and a cable conductor. The elastomer possesses a cylindrical shape which is through up and down; the upper and lower end surfaces of the elastomer are provided with annular stair platforms; the central section of the inside wall and the lateral wall of the elastomer are both concave inward; the central section of the lateral wall of the elastomer is pasted with several foil gauges; the elastomer is sleeved in the sleeve; and the cable conductor is connected with the foil gauges through data lines.
Description
Technical field
The utility model relates to a kind of LOAD CELLS, more specifically to a kind of center pass LOAD CELLS.
Background technology
At present; LOAD CELLS is widely used in all kinds of electronic-weighing equipment such as electronic vehicle weighing apparatus, vapour inspection line, track scale, and it converts measurable electric signal into through the quality signal with weight, and now the most frequently used be exactly resistance strain weighing transducer; Elastic body deforms under the effect of external force; Make attaching foil gauge above that also in company with deforming, its resistance of foil gauge distortion back changes, and converts changes in resistance into electric signal at last.The Chinese patent notification number is CN201285314Y, and the day for announcing is that the utility model name on August 5th, 2009 is called energetically the value side force sensor of weighing, and comprises elastic body, strainometer, can and stressed pressure head; Elastic body is provided with strain bore, and described strainometer is arranged in the strain bore, and can is arranged on the elastomeric outside; Strain bore on the sealing elastomer, elastomeric upper end is provided with installation base, and described stressed pressure head is arranged on the installation base; Though above-mentioned utility model has improved security and reliability of data transmission in survey when being worth energetically; But complex structure is installed and used inconvenience, because the boss contact area is little; When being worth energetically wild effect appears easily in detection, thereby with weighing precision.
Summary of the invention
The purpose of the utility model is to overcome existing load cell structure complicacy, installs and uses inconvenience, and loaded area is too small; Detecting instability when being worth energetically, influencing the technical barrier of weighing precision, providing a kind of simple in structure; Easy to install; Through increasing loading end, the stability of LOAD CELLS, and then the center pass LOAD CELLS of raising weighing precision.
The utility model solves through following technical proposals: a kind of center pass LOAD CELLS; Comprise elastic body, foil gauge, sleeve and cable; Described elastic body is connect up and down cylindric; Described elastic body upper/lower terminal face is provided with annular halfpace, and described elastic body madial wall middle part and lateral wall middle part all cave inward, and elastic body lateral wall middle part is pasted with several foil gauges; Described elastomer sleeve is connected in the sleeve, and described cable is connected with foil gauge through data line.Annular halfpace through the elastic body upper surface carries gravity; The annular halfpace support elastic body of lower surface has increased loading end, has improved elastomeric stability; Simultaneously elastomeric madial wall middle part and lateral wall middle part all cave inward; Elastic body is increased in amplitude of deformation, avoid reducing elastomeric deformation amplitude, influence weighing precision because loading end increases.
As preferably, the thickness after the top end face width of described annular halfpace and the elastomer sidewalls medial recess is identical.Make gravity more directly pass to the elastic body middle part, make it that deformation take place, and then power is passed to foil gauge.
As preferably, be provided with annular groove on the described elastic body lateral wall, be connected with annular ring in the described groove, described annular ring and sleeve are inconsistent.Because elastic body cross-sectional area after the effect that receives gravity increases, distortion has outside thrust to sleeve, and through the conflict of annular ring, with part power bounce-back meeting elastic body, minimizing power is in the total loss of transmittance process.
As preferably, described foil gauge has six, and six foil gauges evenly distribute and elastic body lateral wall middle part.A plurality of foil gauges are measured jointly, improve weighing precision.
As preferably, described sleeve lateral wall is provided with protection module, and described cable is connected with protection module through water joint, and described data line passes through protection module and is connected with cable.The safety of protection cable and data line, anti-sealing, other materials of wet goods influence cable.
Therefore, a kind of center pass LOAD CELLS of the utility model possesses following beneficial effect, and 1, simple in structure, processing, easy for installation; Cost is low, and grease proofing, waterproof, anti-general corrosion property gas and medium are applicable to multiple environment; 2, improve stability through increasing loading end, reduce the thickness of elastomer sidewalls simultaneously, improve deformability; And through annular ring the power of parts transversely is transmitted the resilience gonosome, reduced the consumption of transmitting, improved weighing precision.
