Ceramic Sheathed Sensors are used for high temperature engineering applications such as electrical, electronic, metallurgical and vacuum industries. Ceramic insulators featuring Cordierite or Steatite material offers a low expansion coefficient, high thermal shock resistance, good heat insulation, dimensional stability, and a temperature range up to 1250°C. Fish spline insulators offer a flexible configuration. Thermocouple junctions may be supplied with a welded or twisted junction.
