Ut magna pars estpressura transmitter, Sensorem habet tres momenti Indicatores quod potest determinare utrum pressura transmitter potest praestare mensurae negotium bene, sunt: pressura hysteresis, pressura repeatability, et stabilitatem.
Quisque transmitter debet esse probata et adaequatum cum foliis fabricae ad eam in occursum certa signa et aliqui operas esse optimized cum sensorem folia officinas, et hysteresis est unus ex illis.
Quid est pressura hysteresis?
Per calibration processus pressura transmitter, impressionem sentitur per desolationem diaphragma et pressura-inducens fistulam. Licet initus quantitas erit unicui, directionem et magnitudinem pressura loading et unloading pressura transmitter in ipsa operating conditionibus differentia ducunt ad diversas magnitudinum electrica signo output de pressura transmitter. Misalignment in input-output proprium curvas in deinceps et vicissim ictibus debilitarentur ita dicitur pressura hysteresis.
Factores afficiens pressura hysteresis?
Primo, lets 'take a vultus in components ex diffusa Silicon pressura sensorem!
Diffused silicon pressure sensor is composed of diffused silicon pressure chip, metal base, ceramic insulating cover, silicon oil, metal isolation diaphragm, etc. When pressure acts on the pressure sensor, materials such as diaphragms and chips will deform to varying degrees. Cum pressura est remota, deformatio et evanescet.
Autem, utrum possit restitui ad originale statum pendeat in characteres de ipsa materia, tum eius processus modum, environment et aliis factoribus. Ideo etiam, si idem pressura punctum est initus, in output non coincidunt in deinceps et vicissim ictibus debilitarentur.
Quam ut calculate pressura Hysteresis?
In magnitudine Hysteresis error est plerumque determinari per experimentum modum. Per plures calibration pressura puncta in pressionem range, comparare differentia inter positivum et negans ictu output averages de pressura calibration punctorum, absoluta valorem maximi mediocris differentia et recipis de pleno. Est Hysteresis errore, et Hysteresis error etiam dicitur reditus errore.
In certa temperatus environment, in pressura ex probata sensorem non erexit ad superiorem modum de mensura et pressura reducitur post pressura est confirmatae et redit ad nullus puncto. A test punctum, iterare tres vel ter ad augendam et diminuere calibration cycle,
Quam ad optimize pressura hysteresis?
High-performance silicon piezoresistive pressure chip, through automatic chip bonding equipment, complete chip bonding, using a special diaphragm aging process, release the internal stress of the isolation diaphragm after stamping, ensure the process consistency of important processes, ensure The excellent performance of raw materials reduces pressure hysteresis and improves the overall performance of pressure sensors through processes such as aging and pressure shock.
