Txheej txheem cej luam
PR6426/000-030 yog 32mm txoj kab uas hla, siab -ntau yam tsis sib cuag eddy tam sim no sensor tsim los ntawm German EPRO (tam sim no ib feem ntawm Emerson). Nws yog tsim tshwj xeeb rau cov tshuab loj rotating (Ntau dua lossis sib npaug ntawm 200mm ncej txoj kab uas hla) thiab siv rau kev hloov pauv zoo li qub / kev vibration dynamic xyuas. Nws yog ua ke nrog lub preamplifier (xws li CON021) los tsim TSI system, thiab yog siv dav hauv kev lag luam hluav taws xob, petrochemical, thiab metallurgical industries.

Txoj Cai Ua Haujlwm
Electromagnetic Eddy Current Effect
Tshawb xyuas Excitation
Kev sojntsuam yog nruab nrog lub siab - zaus coil. Lub preamplifier muab siab - zaus alternating tam sim no, generating ib alternating magnetic teb.
Eddy Current Generation
Thaum lub magnetic teb ze rau saum npoo ntawm cov hlau ncej, kaw vortex -zoo li tam sim no (electromagnetic eddy tam sim no) yog induced.
Impedance Modulation
Lub eddy tam sim no thim rov qab tsis muaj zog ntawm qhov qub sib nqus, ua rau lub impedance / amplitude ntawm lub kauj hloov pauv nrog kev sojntsuam - qhov sib txawv ntawm qhov sib txawv (qhov me dua qhov sib txawv, qhov muaj zog ntawm qhov eddy tam sim no, thiab ntau dua qhov amplitude attenuation).
Kev hloov dua siab tshiab
Lub preamplifier demodulates lub impedance hloov mus rau ib tug voltage teeb liab proportional rau qhov sib txawv (2V / mm), thiab outputs nws mus rau lub saib xyuas system rau zaub / tswb / tiv thaiv.
Calibration
Nws yog calibrated nrog 42CrMo4 steel qauv ntawm lub hoobkas. Ntawm -qhov chaw, tsuas yog qhov pib huab cua sib txawv (kwv yees li 5.5mm) yuav tsum tau kho kom siv tau.

1. Tsis yog -txoj kev ntsuas kev tiv tauj
Qhov kev sojntsuam tsis muaj kev sib cuag nrog lub ntsej muag ntawm lub ntsej muag, uas tuaj yeem txo qhov cuam tshuam ntawm kev hnav thiab tsim nyog rau lub sijhawm ua haujlwm ntev -.
2. Muaj feem xyuam rau kev soj ntsuam dynamic
Nws tuaj yeem cuam tshuam qhov kev vibration thiab kev hloov pauv hloov pauv ntawm cov ncej hauv lub sijhawm ua haujlwm, thiab tsim nyog siv rau hauv lub xeev kev saib xyuas.

3. Muaj kev sib raug zoo nrog kev saib xyuas
Nws feem ntau yog siv ua ke nrog EPRO preamplifier thiab saib xyuas module, thiab tuaj yeem ua ke rau hauv kev tiv thaiv kev tiv thaiv ua tiav.
4. Kho kom haum rau kev lag luam ib puag ncig
Nws tseem tuaj yeem tswj xyuas qhov kev ntsuas kev ua tau zoo nyob rau hauv kev lag luam xws li kev hloov pauv kub thiab kev vibrations (qhov kev ua tau zoo tshwj xeeb nyob ntawm kev teeb tsa thiab kev ntsuas ntsuas).
