Made of special high-density reaction-bondedsilicon carbide,the SER STARBAR is a tube with both electrical connections on one end. The hot zone is formed by cutting a double spiral slot which reduces the cross sectional area through which current flows, resulting in higher resistance than the cold end. The cold end is formed by cutting two longitudinal slots along the length of the tube. The SER element is supplied with a ceramic collar cemented to the extremities of the cold end. The cold end of the SER element is flame sprayed with aluminum for a distance of about 50 mm. Flat braided-aluminum straps are held in compression with stainless steel clamps to this metallized area. The clamp is electrically insulated from the flat braid with high temperature insulation. The aluminum braid is 254 mm long and holes are provided for easy connection to the power supply.

* STARBAR SER have same material as SE.
This double spiral cut is place both electrical terminations on the same side of the elements.

* SER can set into the furnace both horizontaly and verticaly.
When elements have a set horizontaly, it is not necessary to support hot zone.
