Mai filifili taavale robotic e conveyor fusipaʻu i le sapalai o le faasologa o galuega i le sway o olo turbine matagi, tulaga lagona o se galuega taua i le tele o ituaiga o applications.It e mafai ona tele ituaiga, e aofia ai le laina, rotary, angular, atoatoa, faʻaopoopoga, faʻafesoʻotaʻi ma le le faʻafesoʻotaʻi sensors.Specialized sensors ua atiina ae e mafai ona fuafuaina tulaga i le taimi nei e tolu posiologic, e mafai ona fuafua tulaga i le taimi nei posiologi i le tulaga e tolu. , capacitive, magnetostrictive, Hall aafiaga, fiber optic, optical ma ultrasonic.
O lenei FAQ o loʻo tuʻuina atu ai se faʻamatalaga puʻupuʻu i ituaiga eseese o lagona tulaga, ona toe iloilo lea o le tele o tekinolosi e mafai e le au mamanu ona filifili mai i le faʻatinoina o se fofo lagona.
Potentiometric tulaga sensors o le tetee-faavae masini e tuufaatasia se ala tetee tumau ma se wiper faapipii i le mea o lona tulaga e tatau ona lagona. O le gaioiga o le mea e gaoioi le solo i luga o le track.O le tulaga o le mea faitino e fuaina e ala i le faaaogaina o se fesootaiga divider voltage faia e ala ma solo e fua ai le laina po o le rotational motion ma se tumau DC voltage (Ata 1 le tau ma le tau e masani ona toe fai.
Inductive position sensors utilize change in the properties of the magnetic field induced in the sensor coil.Depending on their architecture, they can measure linear or rotational positions.Linear Variable Differential Transformer (LVDT) position sensors e faʻaogaina ai vili e tolu e afifi i se paipa omo;a coil muamua ma lua coils lua.O coils e fesootai i le faasologa, ma le vaega sootaga o le coil lona lua e 180° mai le vaega e tusa ai ma le coil muamua.A ferromagnetic autu e taʻua o le armature ua tuu i totonu o le paipa ma fesootai i le mea i le nofoaga o loo fuaina.O se voltage faaosofia e faaaoga i le coil muamua ma se malosiaga electromagnetic coil (EMF) i le tulaga lua coil i le va o le eletise lona lua (EMF). o le armature ma le mea o loʻo faʻapipiʻi i ai e mafai ona fuafuaina.A rotating voltage differential transformer (RVDT) faʻaaogaina le auala lava lea e tasi e siaki ai le rotating position.LVDT ma le RVDT sensors ofo atu le saʻo lelei, linearity, resolution ma le maualuga sensitivity.They e frictionless ma e mafai ona faʻamaufaʻailogaina mo le faʻaaogaina i siosiomaga faigata.
Eddy tulaga i le taimi nei sensors galue ma conductive mea. Eddy o loo i totonu o le taimi nei ua faaoso ai i mea conductive i le i ai o se suiga maneta. O nei ala tafe i se matasele tapunia ma faatupuina ai se lua maneta. , lea e aafia ai le impedance o le coil. A o latalata atu le mea i le coil, o le eddy i le taimi nei gau faateleina ma oscillating voltage oo ina laiti (Ata 2) O le oscillating voltage ua faasaʻo ma faʻagasolo e se laina laina laina e maua ai se laina DC faʻatatau i le mamao o le mea.
O masini o loʻo i ai nei Eddy e gaoa, masini e le faʻafesoʻotaʻi e masani ona faʻaogaina e pei o faʻataʻitaʻiga vavalalata. Latou te faʻaogaina uma ma e mafai ona fuafua le mamao vavalalata i le mea, ae le o le itu poʻo le mamao atoatoa i le mea.
E pei ona taʻu mai e le igoa, o le capacitive position sensors e fua ai suiga i le capacitance e fuafua ai le tulaga o le mea o loʻo lagona. O nei masini e le faʻafesoʻotaʻi e mafai ona faʻaogaina e fua ai le laina laina poʻo le rotational position.They e aofia ai ni papatusi se lua e vavaeeseina e se mea dielectric ma faʻaaoga se tasi o auala e lua e iloa ai le tulaga o se mea:
Ina ia mafai ona mafua ai se suiga i le dielectric tumau, o le mea e tatau ona iloa le tulaga o loo faapipii i le mea dielectric. A o gaoioi le mea dielectric, o le lelei dielectric tumau o le capacitor e suia ona o le tuufaatasiga o le vaega o mea dielectric ma le dielectric tumau o le ea. Alternatively, e mafai ona fesootai le mea i se tasi o le ipu capacitance mamao ma le gaioiina ipu, se mea e le mafai ona gaoioi. e fa'aaogaina e fuafua ai le tulaga fa'atatau.
Capacitive sensors e mafai ona fuaina sesplacement, mamao, tulaga ma le mafiafia o mea. Ona o lo latou mautu maualuga faailoilo ma iugafono, capacitive displacement sensors o loo faaaogaina i totonu o falesuesue ma alamanuia environments.Mo se faataitaiga, capacitive sensors e faaaoga e fua ata tifaga ma talosaga pipii i faiga otometi. I masini alamanuia, latou faaaogaina e mataitu displacement ma meafaigaluega.
Magnetostriction o se meatotino o mea ferromagnetic e mafua ai le mea e suia lona tele po o foliga pe a faʻaaogaina se maneta. o le maneta axial o le maneta tumau (le maneta i le piston cylinder, Ata 3a). O fegalegaleaiga fanua e mafua mai i le mimilo (o le aafiaga Wiedemann), lea e faʻafefe ai le uaea, faʻatupuina se pulupulu acoustic e faʻasalalau i luga o le taʻavale ma e iloa e se masini i le pito o le faʻataʻavalevale (Fig. 3b). o le tulaga maneta ma o lea e mafai ai ona fua le mea (Fig.3c).
Magnetostrictive position sensors e le faʻafesoʻotaʻi masini e faʻaaogaina e iloa ai le laina laina.Waveguides e masani ona faʻapipiʻiina i totonu o le uʻamea uʻamea poʻo le alumini, e mafai ai ona faʻaogaina nei masini i totonu o siosiomaga eleelea pe susu.
A tuu se conductor manifinifi, mafolafola mafolafola i totonu o se maneta, so o se taimi o tafe e foliga mai e fausia i luga o le tasi itu o le conductor, faia ai se eseesega gafatia e taʻua o le Hall voltage. suring le Hall voltage, e mafai ona fuafuaina le tulaga o se mea.O loo i ai faapitoa Hall-aafiaga tulaga sensors e mafai ona fuafua le tulaga i itu e tolu (Ata 4). Hall-aafiaga tulaga sensors e le-faafesootai masini e maua ai le faatuatuaina maualuga ma le vave lagona, ma faagaoioia i luga o le tele o le vevela range.They o loo faaaogaina i le tele o tagata faatau, alamanuia talosaga, taavale ma faafomai.
E lua ituaiga faavae o le fiber optic sensors.In intrinsic fiber optic sensors, o le alava e faʻaaogaina e pei o le sensing element.In fafo fafo fiber optic sensors, fiber optics ua tuʻufaʻatasia ma se isi tekinolosi faʻaogaina e faʻafeiloaʻi ai le faailo i mea tau eletise mamao mo le gaioiga. Fiber optic sensors e puipuia i le electromagnetic interference, e mafai ona mamanuina e galue i le maualuga o le vevela, ma e le mafai ona faʻaogaina, ina ia mafai ona faʻaogaina i tafatafa o le mamafa poʻo mea e mu.
O le isi fibre-optic lagona e faavae i luga o le fiber Bragg grating (FBG) tekinolosi e mafai foi ona faaaoga mo tulaga measurement.The FBG galue e pei o se faamama notch, atagia ai se vaega itiiti o le malamalama e totonugalemu i luga o le Bragg wavelength (λB) pe a faʻamalamalamaina e alaleo lautele malamalama.It ua fabricated ma microstructures etcheded i totonu o le fiber core.FBG fua faatatau e mafai ona faʻaaogaina, faʻalavelave eseese e mafai ona faʻaaogaina le vevela. fa'ae'e ma uta.
E lua ituaiga o masini tulaga opitika, e lauiloa foi o encoders opitika. I se tasi tulaga, o le malamalama e auina atu i se tagata e taliaina i le isi pito o le sensor. I le ituaiga lona lua, o le faailo moli emitted e atagia mai i le mea mataʻituina ma toe foi atu i le puna malamalama. E faalagolago i le mamanu mamanu, suiga i meatotino malamalama, e pei o le umi galu, malosi, vaega po o polarization o se mea faitino e faaaoga e fuafua ai le tulaga opitika laina. O nei masini e pa'ū i ni vaega autu se tolu;encoders opitika transmissive, encoders opitika reflective, ma encoders opitika interferometric.
Ultrasonic tulaga sensors faaaoga piezoelectric crystal transducers e emit high-frequency ultrasonic waves.The sensor measures the reflected sound.Ultrasonic sensors can be used as simple proximity sensors, or sili atu lavelave designs can provide ranging information.Ultrasonic position sensors work with target objects of a variety of material and surface features, ma e mafai ona iloa mea laiti. Infrared radiation ma electromagnetic interference.O faʻataʻitaʻiga o talosaga e faʻaogaina ai masini tulaga ultrasonic e aofia ai le suʻesuʻeina o le maualuga o le suavai, faitau maualuga-saosaoa o mea faitino, faiga faʻatautaia robotic, ma le faʻaogaina o taavale.
E mafai e masini tulaga ona fuaina le atoatoa poʻo le fesoʻotaʻiga laina, rotational ma le angular motion o mea.Position sensors e mafai ona fuaina le gaioiga o masini e pei o actuators poʻo afi. E faʻaaogaina foi i luga o masini feaveaʻi e pei o robots ma taavale. O le tele o tekinolosi e faʻaaogaina i le tulaga faʻatasi ma tuʻufaʻatasiga eseese o le umi o le siosiomaga, tau, saʻo, toe faʻaleleia, ma isi uiga.
