Engineered by SAMSON, the Type 3730-3 electropneumatic positioner integrates a travel sensor, i/p converter, air booster, and microcontroller for high-precision valve control. It compares valve travel/angle to a 4-20 mA signal, outputting pneumatic pressure to actuators. Supports HART for communication and diagnostics, with firmware updates enhancing functionality like automatic option detection and extended configuration periods.
