Electric and magnetic fieldmeter

Electric and magnetic fieldmeter

Those products are used in education, research, industry, personal and industrial safety. They are essential for the monitoring of relevant standards and for the detection of problems in all types of electrical equipment.


ESM 100 : H/E fieldmeter

The application

In nearly all areas of our lives, electricity plays a more and more important     role. One of the side effects of this development are the electromagnetic     fields that, in turn are the cause of fears amongst the population. The     legislative body has reacted to this with various norms and laws like     for example EN V 50166, EN 50366, 26. BImschV, DIN VDE 0848, BGV B11 and     with these, it underlines the necessity to act and do research in this     young branch of modern technology.

Electric Engineering today is constantly revolutionized by new developments     in power electronics and microprocessors. They allow for high-speed processing,     efficient utilization of electrical energy and entirely new application     fields. Disturbances to sensitive controls increase rapidly as the current     intensity and speed raises. Electric and magnetic field measuring meters     are very useful instruments, when it comes to tracking them down. In these     cases, simultaneous measuring of electric and magnetic fields plays an     important role too, since both components can change independently and     unpredictably of each other, resulting in additional interferences.

ESM 120 : Sar Meter

The application

In today\'s industrial society the use of wireless devices which emit     electromagnetic fields is becoming more and more frequent. National and     international norms set limiting values which, for health reasons should     not be exceeded.

The specific absorption rate SAR corresponds to the energy absorbed by     the body in an electromagnetic field. This is used as a base quantity     to evaluate this high frequency electromagnetic exposure and indicates     the power absorbed into the tissue per unit of mass.

This leads to a warming of the tissue and in the case of the relevant     values, to tissue damage. The most sensitive body parts besides the brain     are the eyes. The unit is watt/kg of tissue. In the case of close field     exposure as, for example when using mobile telephones, the SAR limiting     values refer to the maximum average absorption that occurs in the human     body and per 1g or 10g of tissue mass.

The ESM-120 enables a quick and sure determination of the SAR generated     by mobile wireless equipment, antennae, stationary radio plants, base     stations, etc. It is particularly suitable for research, development and     training purposes.
