3730-6 - Electro-pneumatic positioner (HART)
The Type 3730 electro-pneumatic positioner series is designed to work with general industrial applications. This positioner series includes several model versions to meet any end user or process requirements. The basic control positioners are the 3730-0 and 3730-1.
Starting with the 3730-2 the positioner includes full function parameterization and advanced diagnostics. Above the 3730-2 SAMSON introduces communication protocols such as HART (3730-3), Profibus (3730-4), and Foundation Fieldbus (3730-5). Full function parameterization includes characterizing the reference variable, travel range, characteristic (i.e. linear and equal percentage), and performance characteristics (i.e. PID control coefficients). Advanced diagnostics include functions like status message logging, data logging, histograms (travel setpoint deviation, and cycle counter), drive signals (steady and hysteresis), end position trending, static characteristic testing, partial stroke testing, and full stroke testing.
