ABSTRACT (With reference to Figure 1) A sensor for assessing conditions within a metallic high pressure boiler 10. has a sensitive tip section 12, which is insulated from the boiler by virtue of a ceramic spacing member 101. The joins between the member 101 and sensor body 15 and tip 12 respectively are subject to full boiler pressure. The present invention provides a pressure seal by virtue of forming a brazed seal between the parts by forming a ceramic component to be brazed in a ceramic of average gain size of substantially between 5 and 15 microns and of purity exceeding 99% with a maximum silica content of substantially 0.2%, introducing between components a eutectic of substantially the composition: 80% to 90% silver; 5% to 6% copper; less than 6% titantium; and sufficient in quantity to fill gap therebetween, and subjecting the components to a temperature in excess of eutectic liquidus temperature whilst maintaining the components in a vacuum.
