Zirconium is a silver-grey, shiny heavy metal. In its pure form it is easy to work, corrosion resistant even at high temperatures and has a very low neutron capture cross section. In addition, zirconium offers good stability against structural damage caused by neutron irradiation and against cavitation by coolant flows. The metal is mainly used pure or alloyed with 1.2-1.7% tin, for corrosion resistant pipes, fittings and valves in the chemical industry. This special alloy is called Zircaloy. Zirconium plays an important role in reactor construction. It is used for fuel element claddings and holders, for the pressure vessel lining, and for all structural components that come into contact with neutrons. In the rocket and jet aircraft industry zirconium is used for the manufacture of combustion chambers and feed lines. In electron and X-ray tubes zirconium is used as getter material.

Conventional thermometers measure the temperature by means of length or volume change of a material, and are only suitable as display instrument. Temperature sensors from Lenord+Bauer use resistance thermometers that feature an almost temperaturelinear resistance curve, and output the resulting measurement data as electrical signal. They are suitable for a measurement range from 40 °C to +250 °C. A thin stainless steel tube protects the electronics from dirt, humidity and corrosion, allowing the sensors to meet the requirements of protection class IP 68. The sensors are in compliance with fire protection standards EN 45545 and are typetested according to EN 50155. • Platinum resistance thermometer Pt100 / Pt1000 • Measuring tube lengths from 30 mm to 140 mm • Connection with 2, 3 or 4wire technology • Fire behaviour according to DIN 5510 and NF F16101 • Custom configuration
