VII.4. O'lchov asboblari 

 

Ish  joylaridagi  elektromagnit  maydoni  intensivligini  jbaholash 

uchun  elektromagnit  maydoni  hosil  qilayotgan  manba    yaqinida 

maydonning  elektr  va  magnit  kuchlanishlari  ayrim-ayrim  o'lchash  bilan 

belgilanadi.  

Chunki  elektromagnit  maydoni  zonadagi  elektr  va  magnet 

maydonlarining umumiy ta'siri ostida vujudga keladi (29 - rasm).  

 

Elektromagnit maydonining kuchlanishini o'lchaydigan asosiy asbob 

IEMP  -  bva  uning  birmecha  modiflkatsiyalari  mavjud.  Bu  asbob 

yordamida  elektr  maydonining  50  Gs-100  kGs  va  100  kGs-30  MGs, 

shuningdek,  magnit  maydonining  100kGs  -1,5  MGs  diapazonlarida 

elektromagnit  maydonining  kuchlanishini  o'lchash  imkoniyatini  beradi.  

Umumiy ushchi chastotalar  diapazonida kuchlanish qiymati elektr tarkibi 

bo'yicha  5-1000  Vt  va  magnit  tarkibi  bo'yicha  0,5-300  A/m  bo'lganda 

aniqlik darajasi 20% tashkil qiladi.
