RTD elements and sensors - Introduction and tables
Its low resistivity forces the element to be longer than a platinum element, but its linearity and very low cost make it an economical alternative. Its upper temperature limit is only about 120ºC. The most common RTD’s are made of either platinum, nickel, or nickel alloys.
Cerium(IV) oxide - Wikipedia
Cerium(IV) oxide, also known as ceric oxide, ceric dioxide, ceria, cerium oxide or cerium dioxide, is an oxide of the rare-earth metal cerium. It is a pale yellow-white powder with the chemical formula CeO2. It is an important commercial product and an intermediate in the purifiion of the element from the ores. The distinctive property of

What is a resistance - Answers
Resistance is the opposition to flow or movement. Resistance in a a mechanical system could be friction, wind, gravity. Resistance in an electrical circuit is the limiting or opposition
Deep Well Anode System Design | Matcor, Inc.
Dwight’s Model Preserved – Groundbed resistivity more closely approximates Dwight’s model because the actual anode length is the entire length of the active area. 5. Longevity – MATCOR’s system has a longer operating life because of the use of MMO anode and the reduced groundbed stress caused by multiple individual anodes all operating independently and at different outputs.
