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.
Smelting - Measurement Tasks
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
50 Hz, 2 kHz, 10 kHz
ETM-1, EHP-50C, EFA-200/-300
Heating & Hardening - Measurement Tasks
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.
25 kHz ... 100 kHz, 300 kHz ... 10 MHz
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.
Usually 27.12 MHz
Semiconductor Production - Measurement Tasks
production equipment covers wide frequency ranges. For measuring
results conforming to standards it is, therefore, necessary to use
13,56 MHz, 300 kHz...10 MHz, 40..68 MHz, 2,45 GHz
