PR9268/017-100 Txoj Cai Ua Haujlwm
PR9268/017-100 txais cov qauv ntsuas electrodynamic (Electrodynamic / Seismic) thiab yog qhov tseem ceeb ntawm "inertial type vibration sensor".
▶ Cov Qauv Txheej Txheem
Cov qauv sab hauv ntawm lub sensor feem ntau muaj peb ntu:
Inertial Mass (coil sib dhos)
Permanent Magnet (muab magnetic teb)
Damping system (stabilizes teb)
▶ Cov txheej txheem ua haujlwm (qhov tseem ceeb logic)
Thaum cov cuab yeej ua haujlwm thiab tsim kev vibrations:
Lub sensor vaj tse yog tsau rau saum npoo ntawm lub cuab yeej thiab yuav vibrate nrog rau nws.
Internal inertial mass (coil) tsis txav synchronously vim inertia.
Muaj kev sib txheeb ntawm cov kauj thiab cov hlau nplaum.
Raws li txoj cai ntawm electromagnetic induction (Faraday's Law)
▶ Tso zis yam ntxwv
Lub teeb liab tso zis yog ncaj qha proportional rau lub vibration ceev ntawm cov cuab yeej (mm / s).
Lub sensor ncaj qha outputs ib tug analog voltage teeb liab, uas yog ib tug raug ceev - hom tso zis.
Lub teeb liab hloov dua siab tshiab yog ua tiav siv lub hauv paus ntsiab lus ntawm hluav taws xob, tsis tas yuav tsum muaj kev txhawb nqa hluav taws xob sab nraud.
Cov lus teb tso zis muaj cov yam ntxwv zoo linear thiab tuaj yeem cuam tshuam qhov kev hloov ntawm kev vibration.
Nws yog tsim rau kev koom ua ke rau hauv ntau yam kev co xyuas lub tshuab thiab cov khoom siv ua cov teeb liab.

Daim ntawv thov
Lub electro-dynamic transducers PR 9268/01x-x00, PR 9268/20x−x00, PR 9268/30x−x00, PR 9268/60x−000, thiab PR 9268/70x−000 abslute kev ntsuas Lawv ua haujlwm ntawm kev ntsuas seismic. Lub ntsuas coil, tshem tawm ntawm daim nyias nyias, yog qhov seismic loj ntawm cov transducer. Los ntawm kev khiav hauj lwm lub transducer saum toj no resonance zaus, seismic mass yuav nyob twj ywm. Qhov kev sib txheeb ntawm cov khoom siv hluav taws xob hloov pauv (tsiv nrog cov khoom ntsuas) thiab cov coil so ua rau cov teeb liab voltage proportional rau qhov kev vibration tshaj tawm.
