Compacted high performance cartridge heaters with metallic protection tube
2Pages

Typical Applications • The design of these heating elements enables their use in very different operating conditions. • High performance cartridge heaters are suitable to heat up liquid and gaseous media as well as solids. Characteristics • Metallic protection tube made of stainless steel 1.4301 • The outer surface of the cartridge heaters may heat up to more than 500°C. • Cartridge bottom welded to be gas-tight and fluid-tight • Connections made of fiberglass insulated pure nickel leads • Core and insulation out of highly compacted magnesium oxide • Heat wire out of heat resistant alloy NiCr 80/20 • Well suited for use in vibrating environments. This should be analyzed individually for each application. Technical Specifications Standard module: Voltage Output Dimensions and tolerances Max. surface temperature Quality characteristics • Insulation resistance: • Dielectric strength: • Output tolerance: minimum 5 MQ at 500 V DC in cold condition 1500 V AC, 1 second, 5 mA triggering current +5% / -10% Instructions for correct assembly The precise fit of the cartridge heater is very important for good function and performance. The bore should be done with a tolerance acc. to the table below. Technical modifications reserved Eichenauer Heizelemente GmbH & Co.

Compacted high performance cartridge heaters with metallic protection tube bore tolerance temperature measuring point A temperature control is indispensable. We recommend that the temperature measuring point is located at a distance of less than 15 mm to the cartridge heater. . cartridge heater Variations: Power Standard lead length (without thermocouple): 250 mm Standard lead length (with integrated thermocouple Fe-CuNi): 1000 mm Type J (Fe-CuNi) or Type K (NiCr-Ni) As a rule the thermocouple is mounted potential-free, insulated from the metallic protection tube to avoid problems with...
