Extreme accuracy is obtained by linearizing the measurement signal with an accuracy of 0.05 % to the temperature. Thus one transmitter can now replace several of narrower range without reducing accuracy. Leadwire resistance automatic compensation up to 50 ohms makes possible long transfer distances with small-crossarea signel cables. Range can easily be varied by changing the range resistors located under the front plate. Normally transmitters are delivered calibrated according to customer range requirements.
