NTC Thermistors withstand steady-state currents from 6-50 A.
2013-07-30 14:30:07| Industrial Newsroom - All News for Today
Able to withstand 250–800 J of input energy, AS Series limits inrush currents for protection of pre-charge circuits in Li-ion batteries, variable-frequency drives, switch mode power supplies, and audio amplifiers. Uniform temperature gradient throughout disc combined with ability to withstand 400 A per in.² eliminates hot spots from fatigue. Ranging 30–36 mm dia, AS Series features Hot R from 0.0074–0.380 Ω, resistance of .50–50 Ω at 25°C, and max capacitance of 500–1,730 µF at 680 Vac.

Self-Calibrate Your Thermistors for Higher Accuracy
2013-06-10 06:00:00| Industrial Newsroom - All News for Today
Use the Steinhart-Hart Equation for High-Precision Readings<br /> <br /> CHESTERLAND OH — Technicians and engineers often use thermistors to log temperature in applications which require increased accuracy for more demanding projects. To accomplish this, they use the Steinhart–Hart equation to convert a thermistor sensor's resistance to temperature. When compared against other methods, Steinhart-Hart models will give you much more precise readings across the sensors' temperature ...This story is related to the following:Sensors, Monitors and TransducersHVACSearch for suppliers of: Temperature Measurement & Control Thermistors |
