AMWEI PTC Thermistor Heater Description:

PTC Heater is ceramic barium titanate PTC thermistor used for self-regulation constant heating, no glowing parts, no overheating, energy efficient, compact design, long service life.

PTC thermistor positive R/T characteristic means that electric power consumed is automatically adapted to the ambient thermal conditions. At an ambient temperature significantly lower than Tref, i.e. with good heat transfer, the PTC thermistor has low resistance and consumes a relatively large amount of power. If the ambient temperature is significantly higher than Tref or heat transfer is restricted, the resistance of the PTC thermistor rises rapidly and power consumption is limited to a very low value.

Thanks to self-regulation properties, heating devices based on PTC thermistor technology can generally dispense with control and regulating components as well as with over-temperature protection, PTC thermistor heating elements are used wherever measurement and regulating equipment as well as heating devices must be housed in tight confines. There are no glowing parts, because the maximum surface temperature is limited by the R/T curve.

PTC thermistor heating pellet elements can be designed to be square, rectangular,  disc round, ring or doughnut form, or PTC stone housed in aluminum, stainless steel, silicon casing.

PTC Thermistor Heater Features

  • Safe through temperature limiting characteristics.
  • No danger of fires since there are no glowing parts.
  • Dynamic, self regulating, and therefore energy efficient.
  • No excess temperature protection required.
  • Voltages from 6V to 480 V; special voltage applications up to 800 V.
  • PTC thermistor surface temperatures can be set from 50C to 320C.
  • Compact design.
  • Long service life.
