Best-Possible Resistance Materials

The long-term stability of a sensor is a general prerequisite for its quality. Suitable resistance materials must therefore have corrosion resistance and a permanent microstructure in order to have stable electrical properties in the long-term. Only the combination of closely toleranced conductivity, low thermal stress and a very low temperature coefficient of the electrical resistance (TK) make a precision resistance alloy out of a resistance alloy.

Our precision resistance alloys MANGANIN®,ZERANIN®, ISAOHM® and NOVENTIN® are homogeneous mixed crystal alloys and optimally meet these requirements. Recrystallized and stabilized, long-term stability of the resistor can be achieved in the ppm range every year.

Manganin®
 

  • Copper-Manganese-Nickel alloy
  •  Average specific resistance
  •  Very low temperature coefficient and low thermal stress

Zeranin®
 

  • Copper-Manganese-Tin alloy
  •  Low-resistance alternative to MANGANIN®
  •  Improved temperature coefficient to MANGANIN®

Isaohm®
 

  • Nickel-Chromium alloy with additions of aluminium, silicon, manganese and iron
  • High specific resistance
  • Low temperature coefficient

Noventin®
 

  • Copper-Manganese-Nickel alloy
  • Closes the gap with the specific resistance between MANGANIN® and ISAOHM®
  • Lower temperature coefficient
