EM-2108 | 1.5 GHz – 10 GHz -
Electro-Metrics Corp.
The EM-2108 is a standard test fixture for evaluation of the electromagnetic shielding effectiveness (SE) of planar materials. The fixture is a section of coaxial transmission line broken to allow the insertion of planar test materials. Although ASTM D4935-10 is currently limited to an upper frequency of 1.5 GHz, the EM-2108 meets and complies fully with both the impedance and SE requirements called out in ASTM test method D4935-10 up to 10 GHz. These results are shown in Figures 1 & 2. The measured data relates to the shielding effectiveness due to a plane wave (far field EM wave) from which near field values for magnetic and electric fields may be inferred.

400C Series -
CH Instruments, Inc.
The quartz crystal microbalance (QCM) is a variant of acoustic wave microsensors that are capable of ultrasensitive mass measurements. Under favorable conditions, a typical QCM can measure a mass change of 0.1-1 ng/cm2. QCM oscillates in a mechanically resonant shear mode under the influence of a high frequency AC electric field which is applied across the thickness of the crystal. Figure 1b below shows an edge view of a QCM crystal undergoing oscillatory shear distortion. The central portions of the top and bottom of the crystal are coated with a typically disk-shaped thin metal film (e.g., gold).

EMP -
Keystone Compliance
An electromagnetic pulse (EMP) is a short burst of electromagnetic energy that can be extremely damaging to electronic equipment. EMP energy can be transferred in the form of electromagnetic radiation, an electric field, electrical conduction or a magnetic field. Since EMPs have a short duration, their impact can occur across large ranges of frequencies. EMPs can be produced naturally, occur from man-made equipment. Natural EMPs include lightning strikes and electrostatic discharges (ESD), geomagnetic storms/coronal mass ejections of solar origin. Man-made EMPs include power line surges, pulses created by ignition systems, nuclear electromagnetic pulses (NEMP) and non-nuclear electromagnetic pulses (NNEMP).

Guangzhou Jumho Electric Co., Ltd.
Cell phones and other wireless devices radiate powerful electromagnetic fields that can cause interference and noise in microphone signals. The interference and noise is called RF interference, which is an unwanted “signal” that occurs at the same time and frequency as a data signal. The RF interference disrupts the flow of data and degrades quality-of-service. Jumho Electric provides a cost-effective RF interference test system for GSM interference level measurement of wireless microphone.

General Tools & Instruments
Moisture Meters fall into two categories, pin-type and pinless. Pin-type Moisture Meters measure the resistance between test pins inserted into a piece of wood or a building material and use that reading as a proxy for the object''s absolute moisture level. The wetter the material, the less ready it is to be sanded, painted, finished or covered. A best seller is the MMD4E Pin-Type Moisture Meter. Pinless Moisture Meters rely on the ability of moisture to inductively distort an electric field created by turning on the meter. Although Pinless Moisture Meters can only make relative readings, they are nonetheless useful for pinpointing the source of a leak above a ceiling, and for leaving no unsightly pinholes on a finished surface. The MMD7NP is a best selling pinless moisture meter.

Panasonic Automotive & Industrial Systems Europe GmbH
There are many production processes where electrostatic charges disturb smooth operation. To eliminate static, ionizers are used. One typical field of application is the semiconductor industry where the components are extremely sensitive and can even be damaged by high electric static charges. Another example is the printing industry: Here friction between the rollers and the paper generates static. The static makes the paper cling and not move correctly through the printing machine. Especially when printing on vinyl or plastics, electrostatic charges need to be removed. In the packaging industry, plastic sleeves or foils tend to stick to each other, which can be prevented with an ionizer eliminate static. A general problem in assembling processes is the adhesion of dust and dirt particles. Contamination of workpieces can be prevented by having static eliminators neutralize and blow away undesired particles.
