Tempora strip heaters consist of helically wound coil inserted in specially designed ceramic insulators. The ends of the coil are then fixed to the terminals. The rest of the hollow space in the rectangular stainless steel tubing is then filled with grade 1 magnesium oxide to a high density to ensure conductivity and maximize dielectric strength.
Maximum Watt density: 25 Watts/in2
Maximum temperature: 1190ºF (640º C)
Formula for Watt density
Watts/sq.in = Total Wattage
