Operating 
                    on the principle that resistance of any given metal changes 
                    with temperature, Thermo Electric RTD's are the sensors of 
                    choice in applications where accuracy, stability and repeatability 
                    are critical. To maximize linearity and temperature ranges, 
                    Thermo Electric specializes in the use of high-purity platinum 
                    elements. In addition, a special high temperature platinum 
                    RTD'S delivers high stability and durability at 650°C 
                    (1202°F). Thermo Electric RTD's are available in diverse 
                    configurations with two-,three- and fourwire construction 
                    ranging from -200°C to 650°C (-328°F to 1202°F). 
                    Tolerances meet the standards of ASTM E1137 Grade A or B and 
                    IEC 751 Class A or B. depending on your needs.
