As the progress of appearance technology, all sorts of brand difference are pressed change send implement change directional development towards high accuracy, intelligence. However technical progress brought an error for architects: People goes in the choice send implement when, often pay attention to its oneself precision, and the other factor that ignored an influence to measure precision. Actually, what the user needs truly is the real cost that can reflect the cost that be measured correctly -- measure precision, and rather than changes send implement the precision of oneself. The influence changes send implement the factor that measures precision is very much, some elements still reach installation with ambient conditions means is relevant. Accordingly, when the design, product oneself precision can not assure actual measurement the effect, architects not only the real environment impact to product precision should consider when type selecting, when also wanting to notice to be being installed, reduce as far as possible send to changing implement the influence of precision. So, what element can be pressed to difference change send implement cause an effect? The influence difference that appearance accused gentleman to arrange span of the following ~ to compare for everybody is pressed change send implement span comparing is to point to to change below the circumstance that asks in contented precision send implement of the maximum that can measure and the least value than. Usually, span comparing is bigger, its measure precision lower, pressure changes send caliber Cheng to compare big, have a lot of profit, a such appearance move school hind, can use in many different situations. But actual in what span comparing moves is too tall, can bring a lot of issues that measure stability. Most difference is pressed change send implement in 10:1inside span comparing limits, precision still is referenced precision, do not suffer the effect that span compares. But still have quite quantitative difference is pressed change send implement the span that assures referenced precision is compared be less than 10:1, this one index returns 3:1 evenWith 2:1; And the different span code name of same type product, assure the difference with the very bigger than appearing possibly also span of referenced precision, this requires special attention when the precision that the user suffers span to compare influence hind in computation. The influence difference of temperature is pressed change send implement in process application, process temperature, environment temperature can produce very big change, affirmative meeting and change send implement the reference condition when the test is different, this also means the referenced precision of function general and place introduction to differ. Temperature changes to difference pressing send implement the influence is close to maximum Cheng (namely grain Cheng is compared) when very small, but be close to minimum Cheng (namely a large number of Cheng are compared) when the impact is very big, exceeded our imagination even sometimes. Offer temperature to be opposite according to manual of a few products the combined influence formula of precision and span precision is medium at 0 o'clock, if input maximum Cheng to compare for 100, can get immediateness the influence of 10% . Pressure of a few contemporary intelligence changes send implement product, increased internal temperature sensor, with the hot effect that causes at amending environmental temperature to change. Static the influence that the impact that control is similar to temperature and span, static pressure send to changing implement there also was materiality effect with the precision of span at 0 o'clock. Like capacitance type difference pressing changes send implement, this kind changes send implement in producing machining complex to run a course, can get almost static the impact that control, when the Jing Yachao of operating conditions is worth certainly too, its are static the error that controls an impact will change more than send implement the precision of itself, when undertaking to measuring a passageway passageway precision is calculated, if join static press influence error, cannot satisfy passageway precision requirement possibly, because difference of this capacitance type is pressed,change send implement must be opposite when desired result static press an influence to undertake correction. Installation banking angle is spent send to changing implement the influence installs banking angle to spend is to point to change send implement after installing the spot, change send implement in the included angle between axes and plumb line. When difference pressing is measured, the deformation displacement that through detecting the center measures diaphragm will feel both sides pressure feel detecting element to differ. Because the center is measured indoor was full of fill to fill silicone oil, v pressing changes send implement along perpendicular at measuring diaphragm plane direction tilts when, fill fills silicone oil itself to be able to generate pressure to measuring diaphragm, cause diaphragm deformation, those who cause output value is fluctuant. And v pressing changes send implement along what tilt with the way that measures diaphragm plane parallel when, fill fills silicone oil to won't oppress measure diaphragm, because this does not have an influence. Of different span change send implement suffer tilt the level of the influence is different, span is smaller, the impact is bigger; V pressing changes send implement when pitch and tilting back ward, its output linear and output value change are not apparent, won't affect its to be used normally; V pressing changes send implement left or when Right deviation, its output a value to will spend the drift that produces only way according to banking angle, point of view is older, the impact is bigger, but linear won't have apparent change. Measurement point and the influence that installation dot needs highly because industrial spot is overall the need of the design, difference pressing changes send implement often cannot install the measurement point that using the site around, press a canal to bring through bringing however overwhelm a place that centers quite, so that protect and manage at dimension, this can cause measurement point and installation existence height is poor between the dot, bring press a canal to be passed mediumly press medium to because high difference generates additional pressure,be met, produce an effect thereby, fetching and add error. In flow industry application, the density as a result of medium often bigger, accordingly even if lesser height is poor, the add error that introduce also is bigger. CNC Milling
