SAMSON定位器3730系列介紹

3730 型電氣-氣動定位器系列旨在用于一般工業(yè)應用。該定位器系列包括多個型號版本，以滿足任何終端用戶或工藝需求?；究刂贫ㄎ黄鳛?3730-0 和 3730-1。

從 3730-2 型開始，定位器具有完整的功能參數(shù)化和先進的診斷功能。在 3730-2 型以上，SAMSON 引入了多種通信協(xié)議，如 HART（3730-3）、Profibus（3730-4）和 Foundation Fieldbus（3730-5）。完整的功能參數(shù)化包括對參考變量、行程范圍、特性（即線性和等百分比）以及性能特征（即 PID 控制系數(shù)）的表征。先進的診斷功能包括狀態(tài)信息記錄、數(shù)據(jù)記錄、直方圖（行程設定偏差和循環(huán)計數(shù)器）、驅動信號（穩(wěn)態(tài)和滯后）、端位趨勢、靜態(tài)特性測試、部分行程測試和全行程測試等功能。

3730 系列的最新型號是 3730-6，它是 3730-3 型的升級版本，配備 HART 協(xié)議，并包括壓力傳感器以監(jiān)測供給和輸出壓力。

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. 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 protocol 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). Advance diagnostics includes 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.

The latest addition to the 3730 series is the 3730-6 which is an upgraded version of the 3730-3 with HART that includes pressure sensors to monitor supply and output pressures.
