Case Expansion Transmitters are compatible with LVDT inputs and provides a 4-20 mA output proportional to the overall measurement. Each unit provides power for the associated transducer, processes the signal and outputs a 4-20 mA dc current that is proportional to a user specified range such as 0-2.0 inches. The electrical specification includes +24 Vdc at 45 mA max. power, 0.5 % of full scale range accuracy and maximum load of 600 Ohms resistive.
