PCE Instruments
A gauss meter displays electromagnetic wave measurements in Gauss (G), milliGauss (mG), milliTesla (mT) or microTesla (µT) units. A gauss meter can detect either static (DC) permanent (rare-earth) magnetic or dynamic (AC) electromagnetic fields (EMFs), or both. Thus, it is important to review the specifications of a gauss meter prior to purchase to ensure suitability for the intended application.Neodymium (NdFeB) permanent magnets are among the world's strongest and most widely used magnets. When testing magnets made of neodymium or other rare-earth elements, a gaussmeter or magnetometer capable of measuring DC magnetic fields is required. However, most electromagnetic fields encountered are generated by AC currents. Examples include electrical power lines, transformers and wiring for overhead lighting, solar panels and other electrical devices and equipment. Electromagnetic fields from electrical installations are believed to cause feelings of nervousness, anxiety and paranoia in EMF-sensitive human beings.Most gaussmeters offered by PCE Instruments can be calibrated and certified according to DIN ISO 9000 standards for an additional fee. Replacement gaussmeter probes and optional accessories are available for most gaussmeter models.

DiskMapper H7 System -
MicroSense, LLC
The DiskMapper H7 system quickly determines the uniformity of the perpendicular recording layer of Heat Assisted Magnetic Recording (HAMR), also called Thermally Assisted Recording (TAR) disks, immediately after deposition, an important factor in the yield of disk drives. Utilizing a custom 7 Tesla bi-polar high speed superconducting magnet, the hysteresis loop of any disk location can be measured in less than 3 minutes.

M-011 -
Physik Instrumente GmbH & Co. KG
M-011 ultra-high-precision magnetically-coupled stages use the force of integrated magnets to preload the bearing. This magnetic preload results in extremely uniform and smooth motion with minimum friction. Unlike conventional stages, where two bearings with limited parallelism guide the carriage (inducing runout and rotational errors) in M-011 stages, only one of the two linear bearings has a guiding function (V-groove) while the second bearing is for support only (U-groove).

Carl E. Holmes Company
Surge suppressors are used to protecting circuits from transients (sudden, brief increases in voltage). Transients of widely varying magnitudes are caused by such circuit components as motors, coils, magnets, relays, and transformers. They are found in all electrical systems and are notorious for damaging diodes, SCRs, transformers, triacs, and relay contacts.

Kobold Instruments, Inc.
Magnetic level switches are used for the monitoring and control of liquid level in tanks. These level switches are specifically manufactured to customer specifications. The float switches are manufactured with a hermetically sealed contact which is located within the guide tube. The float sliding on the tube contains a ring magnet which activates the sealed contact in a non-contacting fashion. The sealed contacts are available as SPST (N/O or N/C) or SPDT (N/O + N/C). The float sliding up and down on the guide tube is the only moving part on the M-series magnetic float switches.

605-00005 -
Parallax Inc.
Parallax has worked with the Melexis 90217 sensor in applications including CNC milling machine spindle speed measurement and feedback on motor RPM. With the CNC milling machine it reliably measured the top spindle speed of 7,500 RPM. This is a cost-effective and highly functional hall-effect sensor. The Melexis 90217 is designed to be used with a bias magnet (#605-00006) south facing the back (non-marked) side of the IC. With a single Hall plate, this sensor is immune to common rotary alignment problems. Very easy to interface with all microcontrollers.

AC Rectifier Type Coil Meter -
Bee Instruments
measures the alternating voltage and current with the help of rectifying elements and permanent magnet moving coil type of instruments. However the primary function of rectifier type of instruments work as voltmeter. Now one question must arises in our mind why we use rectifier type of instruments widely in the industrial world though we have various other AC voltmeter like electrodynamometer type instruments, thermocouple type instruments etc? The answer to this question is very simple and is written as follows.

Bee Instruments
Magnetic proximity sensors are characterized by the possibility of large switching distances, available from sensors with small dimensions. They detect magnetic objects (usually permanent magnets), which are used to trigger the switching process. As the magnetic fields are able to pass through many non-magnetic materials, the switching process can also be triggered without the need for direct exposure to the target object. By using magnetic conductors (e.g., iron), the magnetic field can be transmitted over greater distances so that, for example, the signal can be carried away from high temperature areas.
