Spring/Non-Spring-Loaded Thermocouple
8PT25
-
The AMETEK 8PT25 Spring/Non-Spring-Loaded Thermocouples for Frame 6, 7 and 9 applications have been designed, fully tested and qualified to meet OEM specifications. Power Instruments’ expertise in solving creep, stress rupture, corrosion, EMF drift and other problems affecting sensor performance has resulted in a robust line of single and dual element thermocouple designs. This thermocouple is immersed directly into the turbine fluid to monitor temperature while in operation.

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.

Motor Starting & Control Resistors
-
Motor Starting Resistors are used to reduce the voltage at the motor terminals and also decrease the starting current. Motor Starting Resistors are necessary because the self resistance of a motor armature is very low. When the voltage is first applied, excessive current will flow. For limiting this current, since there will be no resisting back electromotive force (emf),some series resistance can be added to the armature windings.

Milliohm Meters
Chroma 16502
-
Chroma Systems Solutions, Inc.
With a basic accuracy of 0.05%, Chroma 16502 offers a 0.001mΩ ~1.9999MΩ wide measurement range. It provides measurement range with 4 1/2 digits resolution. The fast measurement time is 65 ms. It suits component evaluation on production line. Pulsed test current output mode is used to reduce thermal EMFs affection on milliohm measurement. DC test current output mode is used to fasten measurement speed for inductive DUT. Dry-circuit test current output mode is used to measure such contact resistances where the maximum open-circuit voltage must be limited to 20mV.
