A NWT-ST/ZS is assembled by winding a platinum wire that is double insulated by a fibreglass surround a HGW-carrier body in a bifilar winding method. The special strain relieved connection is available in 2-, 3- or 4- wire circuitry to connect the measuring winding wire.  The carrier body is insulated by several layers of mica paper. The slot resistance thermometer is laminated with woven fibreglass which is soaked in resin to increase the mechanical stability. This design provides greater rigidity to the fixture body. Therefore the bar can be inserted into the slot without damage - even at increased pressure. The dielectric strength is also significantly increased compared to NWT-ST.
