Industry
Plants for electrolysis, smelting, heating, hardening, plastic welding and semiconductor production should be regarded as radiation sources.
Electrolysis - Measurement Tasks
Static fields are to be measured. Meters with a measuring range up to 2 Tesla are recommended.
Frequency range
0 Hz
Recommended Equipment
ETM-1
Smelting - Measurement Tasks
Powerful magnetic fields can be produced during smelting, rising dramatically in the immediate vicinity of the field source. For the protection of both personnel and equipment, these sources should be approached with caution. The extra function STD (EFA 200/300) makes measurement considerably easier, since not necessary for the user to know the signal shape.
Frequency range
50 Hz, 2 kHz, 10 kHz
Recommended Equipment
ETM-1, EHP-50C, EFA-200/-300
Heating & Hardening - Measurement Tasks
Machines for the heating of metals are offered in a wide variety of frequency ranges. The frequencies can change depending on production requirements. High magnetic field strengths can be produced. So the meter used should have a wide dynamic and frequency range.
Frequency Range
25 kHz ... 100 kHz, 300 kHz ... 10 MHz
Recommended Equipment
EHP-200
Plastic Welding - Measurement Tasks
Very high local field strengths can be produced near the welding electrodes. It is essential to check the E and H fields.
Frequency Range
Usually 27.12 MHz
Recommended Equipment
8513
Semiconductor Production - Measurement Tasks
Semiconductor production equipment covers wide frequency ranges. For measuring results conforming to standards it is, therefore, necessary to use broadband meters.
Frequency range
13,56 MHz, 300 kHz...10 MHz, 40..68 MHz, 2,45 GHz
Recommended Equipment
8511, NBM Series, NBM520
