Description
Technical field
The utility model relates to a kind of strain ga(u)ge, particularly a kind of engineering plastics film substrate strainometer.
Background technology
At present, known foil resistance strain gauge be by the macromolecule resin insulating material as substrate, on the metal foil of compacting by rolling, form sensitive grid with photoetching, lithographic technique then, and form the weldering end in the rear end and make.The main base material kind of using has: epoxies, phenolic, polyesters, acetals, polyimide, sheet metal, interim substrate etc.Existing on the market, what be most widely used is epoxies, phenolic, acetals.The foil resistance strain gauge of this several types substrate can't satisfy accurate LOAD CELLS, standard transducer, the weighing apparatus needs with sensor, force transducer, Industry Control, stress analysis etc.Particularly these foil resistance strain gauges are because substrate or sealant thickness range broad, and the creep consistance, to return zero consistance relatively poor, comparatively responsive to environmental changes such as humidity, temperature, causes that strainometer resistance and zero signal change; This class strain gauge creep performance can vary with temperature simultaneously, is not easy control with conventional compensation method, can only be used for the fixing occasion of temperature range.Therefore substrate and sealant are influenced by environmental change to become the maximum error source of strainometer in measuring.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model is to provide a kind of engineering plastics film substrate strainometer, to humidity, water and other liquid relative insensitivity, the damp and hot variation that environment causes influence relatively is less, has stable creep, zero restoring ability energy.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of engineering plastics film substrate strainometer, comprise engineering plastics film substrate 1, engineering plastics film substrate 1 bonds together by adhered layer 2 and metal forming 3, be cap rock 4 on the metal forming 3, engineering plastics film substrate 1 is PPS (polyphenylene sulfide) films or poly (ether ether ketone) film.
Described adhered layer 2 is epoxy resin or phenolic aldehyde-epoxy resin.
When engineering plastics film substrate 1 was PPS (polyphenylene sulfide) films, cap rock 4 was a PPS (polyphenylene sulfide) films.
When engineering plastics film substrate 1 was poly (ether ether ketone) film, cap rock 4 was a poly (ether ether ketone) film.
The utility model is more stable than existing strainometer performance, consistance is better, serviceability temperature scope with broad, engineering plastics film substrate 1 is PPS (polyphenylene sulfide) films or poly (ether ether ketone) film layer, the PPS (polyphenylene sulfide) films heatproof can reach 175 ℃, the poly (ether ether ketone) film heatproof can reach 230 ℃, can be the supporting use of production standard sensor.
