Resistance Thermometer HOW IT WORKS: By means of a special circuit in the Wheatstone bridge, the reading of the balancing variable resistor is made to follow a second degree relationship corresponding with the change in resistance of platinum with temperature. This gives a direct reading instrument which eliminates the time consuming calculations normally required with high precision resistance thermometry. A high sensitivity elec tronic detector permits rapid and precise balancing of the bridge.
