Many makers of cartridge heaters, specify wattage tolerance as (+/-) 10%. Since wattage is a function of the square of voltage divided by the resistance, a change in the voltage will result in ...
The useful life of a cartridge heating element is determined by how quickly the heat generated in the resistance wire can be dissipated to the outside sheath. To accomplish a useful life of the heater, two methods of manufacturing cartridge heaters are available; STANDARD cartridge heaters and SWAGED cartridge heaters....
The graph is based on a 1400°F resistance wire temperature inside the cartridge heater, when the heater is installed in an oxidized mild steel block. Watt density values from the graph should be lowered by about 10% or more when other materials are used which have a lower thermal conductivity or lower emissivity than oxidized mild steel....
In terms of safety, a 30W heater cartridge does not come with any risks. In the event of a thermal runaway situation it maxes out at about 300°C (572°F), or 420°C (788°F) with a silicone sock. ...
