Instrumentation Amplifiers
Analog Devices instrumentation amplifiers (in-amps) are precision gain blocks that have a differential input and an output that may be differential or single-ended with respect to a reference terminal. These devices amplify the difference between two input signal voltages while rejecting any signals that are common to both inputs. The in-amps are widely used in many industrial, measurement, data acquisition, and medical applications where dc precision and gain accuracy must be maintained within a noisy environment, and where large common-mode signals (usually at the ac power line frequency) are present.

Gauss Meters
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.

Universal Power Line Carrier
UPLC-ll
As with our previous UPLC power-line carrier design, UPLC-II requires no hardware modifications for most required configurations. UPLC-II is frequency programmable across the entire power-line carrier spectrum (30 to 500 kHz) without changing any hardware components. UPLC-II can be software configured either as an ON/OFF or frequency-shift keyed (FSK) power-line carrier unit without changing any hardware components. This flexibility makes each UPLC-II universally suited for any directional comparison blocking, permissive, phase comparison or transfer trip protective relay application.

DALI Distribution And Commissioning
UBi
Every UBi can create up to 6 branches of a DALI line. Simply put a DALI line into one of the 2-way pluggable terminals, and then use any combination of the 5 remaining terminal pairs to route your cable anyway you like. Or, if you want the UBi to be a power supply, simply power a UBi Power with 24VDC and it will power your DALI line with 21.9VDC 245mA and still give you 5 DALI connections – one for your DALI controller and four to branch however you like.
