  • 產品簡介:
    • 此探棒是一組3個彼此正交的霍爾感測器,在探棒的輸出端,提供對應於場的空間分量的3個電壓,寬頻電磁場分析儀NHT310或選頻/寬頻電磁場分析儀NHT3D即用於計算因此產生的3軸向場強。
    • 此探棒可偵測頻率範圍0~1000Hz的磁場,極適合例如磁共振成像(MRI)、材料加工廠(電鍍及銑削)及火車站供電設備等應用領域。
    • 探棒的高靈敏度,使其適合在敏感環境進行人體曝露於磁場的測量,例如有植入心律調節器的病人的場所。
    • 由於具有截止頻率1.5Hz的一階高通濾波器(20dB/十倍頻),可於較高頻率區分靜磁場分量與其它分量。事實上,在插入此濾波器時,即可完全抑制連續分量,而探棒頻帶變成1.5Hz~1000Hz。

  • High pass filter (cut-off@1.5Hz)
  • Compatibility: NHT310 and NHT3D meters
  • Typical Applications:
    • Locations where there are patients with pacemakers
    • MRI - Magnetic Resonance Imaging
    • Galvanic treatments
    • Railway Power Supply Plants
    • Metalworking processes
  • Description:
    • The 30H probe is based on a set of three mutually orthogonal Hall sensors. The three voltages, which correspond to the spatial components of the field, are available individually at the probe output. The NHT 310 or NHT 3D meter calculates the resulting isotropic field strength.
    • The probe detects magnetic fields from 0 to 1000 Hz. It is suitable for use in applications such as Magnetic Resonances Imaging (MRI), materials working plants (galvanic and mills) and power supply plants for railway stations.
    • The high sensitivity of this probe makes it ideal for exposure measurements in sensitive environments, such as places where people using peacemakers are present.
    • The presence of a first-order high-pass filter (20 dB / decade) with a 1.5Hz cutting frequency allows to discriminate the static component from the others at higher frequencies. In fact, the filter, when inserted, completely suppresses the continuous component and the probe band becomes 1.5 Hz ÷1000 Hz.
