Product Description

Product Description

3730-5 Electro Pneumatic positioner(FF)

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.

Special features

Communication Feature: Utilizes Foundation Fieldbus communication, enabling seamless integration with compatible industrial control systems. It supports efficient data exchange, allowing for remote parameter configuration, real-time status monitoring, and control signal transmission.
Function Blocks: Integrates multiple function blocks such as 1 PID control, 1 AO, 1 MAO, 1 MAI, 2 DO, and 2 DI. The DO function block can perform discrete analysis for on/off valve operations and initiate various functions (like starting partial stroke testing). The 2 DI function blocks are for processing digital input signals.
Easy Installation and Operation: Can be easily installed on control valves with Samson direct integrated mounting interfaces, NAMUR flanges, or rod-type brackets compliant with IEC 60534-6, as well as on rotary actuators compliant with VDI/VDE 3845. It has a simple single-knob, menu-driven operation and an automatically startable feature. The LCD display can have its reading direction selected for easy reading in any mounting position.

Advantages

High Communication Compatibility: The Foundation Fieldbus communication protocol ensures good compatibility with a wide range of industrial control systems and field devices that support this protocol, facilitating system integration and information sharing in industrial automation networks.
Precise Control: With its advanced control algorithms and integrated PID function block, it can achieve precise positioning control of valves, ensuring stable process parameters and meeting the high-precision control requirements of various industrial processes.
Intelligent Diagnosis and Maintenance: The comprehensive EXPERT plus diagnostics function can detect potential faults and abnormal conditions of valves and positioners in a timely manner, providing detailed diagnostic information. This helps in predictive maintenance, reducing downtime, and saving maintenance costs by allowing proactive troubleshooting before serious failures occur.
Operational Flexibility: The adjustable functions and full-function parameterization enable users to customize the operation of the positioner according to specific process requirements. The easy installation, simple operation, and rotatable display also improve the convenience of on-site operation and maintenance.
Reliable Performance: The use of a non-wear travel sensor and non-volatile EEPROM for parameter storage, along with its ability to operate in a wide temperature range and potentially high protection level (similar to other models in the series), ensures the reliable and stable operation of the positioner in various industrial environments.
Function Integration: The integration of multiple function blocks reduces the need for additional external devices in the control system, simplifies the system structure, and improves the overall efficiency and reliability of the control system.
