Metal-ceramics resist surface deformation below the maximum recommended operating temperature of 1355°C (2500°F). They are useful in calcining kilns, for preheat temperature control of open hearth furnaces, for continuous immersion in molten brass, bronze, copper, zinc and lead and in sulphurous gases. In use, excess thermal or mechanical shock should be avoided. Though superior to ceramics, metal-ceramic tubes are not as shock resistant as metal alloys, and may require preheating for certain applications. Note: Not recommended in molten aluminum. in. | | | | | | | | | | O.D.7/8in. (22.2 mm) | | I.D. 5/8 in. (15.9 mm) | | | | | | | | | | | | | | L | | | | | | | | | | 5/8in. (15.9 mm) Watlow's SERV-RITE® metal-ceramic protecting tube is composed of metallic chromium and aluminum oxide. The metal imparts shock resistance and high thermal conductivity for fast, precise readings; the stable ceramic resists deformation, corrosive attack, abrasion and oxidizing atmospheres over 1205°C (2200°F). | | | | | | | | | | Construction | | | | | | | | | | | | | | Std. % inch conduit connector | | | | | | 1161 | | | 12, 18, 24, 30, 36 | | | | | | | | | | | | | | Note: All accessories subject to minimum purchase quantities. | | | | | | | | | | 151 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
