VLF Magnetic Probe

VLF MAGNETIC PROBE

5 kHz - 1 MHz

These passive magnetic field sensors output AC voltage corresponding to the AC magnetic field strength. The frequency of the AC output voltage is the same as the frequency of the magnetic field. Single-axis, so it responds to fields parallel to the sensor axis. The sensor orientation shows the magnetic field polarization. No battery or power supply is needed.

VLF Magnetic field Probe Connect to a display instrument (not included) such as AC voltmeter, oscilloscope or spectrum analyzer to display the output AC voltage and waveform information. These sensors have no minimum measurable field strength, so the sensitivity will depend on your display instrument. Maximum field: the sensor can be damaged above approximately 50 Volts output. Sensor includes operating instructions.

Frequency Range:
For 5 kHz - 1 MHz, the sensor output voltage is at least 70% of the magnetic field strength in Gauss (Volts/Gauss > 0.7). Sensors can also be used below this frequency range, but will have lower output voltage.

Calibration: Each individual sensor is tested and recorded to ensure NIST traceable accuracy. Individual calibration data table is delivered with each sensor.

Rectangular 1"x1"x0.8" and has a BNC (female) output connector on the case. Weighs only 1 oz (30 g).

Magnetic Pickup

MAGNETIC PICKUP


Build Your Own Gaussmeter

Want parts to build your own gaussmeter? Here is an AC magnetic field probe. It generates an AC voltage when exposed to AC magnetic fields. Although we do not know how the output from this unit varies with frequency, we do know that the greater the magnetic field, the higher the voltage generated (at 60 Hz, it produces about 1 mV per 20 mG). It can be connected to a DMM, analog voltmeter, oscilloscope, Audio Amplifier (see below), or recording device. Connect 3 of them in series and create a 3-axis unit. It is quite small: only 0.7" long x 0.7" diameter, with a removable rubber suction cup attached. Has 36" lead and 1/8" (3.5 mm) mono plug.

AC/DC CLAMP METER

AC/DC CLAMP METER

Best Way To Locate Net Current

Place the jaws of this clamp meter around wires, pipes, conduit, hoses, or any other object (up to 42mm diameter) to determine if magnetic field producing electric current is flowing. It’s the easiest way to check your water main, radiator pipes, and wires without disconnecting them. Net current and many wiring errors can be detected when the current in the hot lead does not equal the current in the neutral… or worse, if there is current running on the ground wire. This is a “must have” tool for EMF consultants and other EMF detectives.

    This unit also has many other very useful features:
  • True RMS for AC voltage and current
  • Auto/manual range
  • Data hold
  • MAX / MIN function
  • AC/DC voltage, AC/DC current, resistance, frequency
