<p>A two wire current transmitter for controlling the total current in the two wires in accordance with a value of a parameter to be sensed, which provides for substantial linearization of the electrical characteristic representative of the value of the parameter to be sensed by adjusting the current from an adjustable current control to substantially compensate for the nonlinear relationship of the parameter to be sensed versus the electrical output of the sensor of said parameter. The circuit also provides for substantial compensation for sensor lead wire effects.</p> |
