A thermistor is a semiconductor type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. The word thermistor is a portmanteau of thermal and resistor. Thermistors are divided based on their conduction model. Negative Temperature Coefficient (NTC) … See more Depending on materials used, thermistors are classified into two types: • With NTC thermistors, resistance decreases as temperature rises; usually due to an increase in conduction electrons bumped up by … See more In practical devices, the linear approximation model (above) is accurate only over a limited temperature range. Over wider temperature ranges, a more complex … See more When a current flows through a thermistor, it generates heat, which raises the temperature of the thermistor above that of its environment. If … See more The first NTC thermistor was discovered in 1833 by Michael Faraday, who reported on the semiconducting behavior of silver sulfide. … See more Thermistors are typically built by using metal oxides. NTC thermistors are manufactured from oxides of the See more NTC (negative temperature coefficient) Many NTC thermistors are made from a pressed disc, rod, plate, bead or cast chip of semiconducting material such as sintered metal oxides. They work because raising the temperature of a semiconductor increases the … See more PTC • As current-limiting devices for circuit protection, as replacements for fuses. Current through the device causes a small amount of resistive heating. If the current is large enough to generate more heat than the device can … See more WebJust add salt to generate all the chlorine your pool needs. iChlor produces a steady stream of pure chlorine for softer, silkier pool water. It’s the easiest and most effective way to maintain a sparkling clean pool. Real-time data for fast and easy monitoring. Adjust sanitizing level in one-percent increments from 1-100%.
