Samson 3730-18000000000000000.02 3730-3 Electropneumatic positioner

The 3730-18000000000000000.02 is a model within Samson’s 3730 series of electropneumatic positioners, designed for precise valve positioning in industrial process control systems. Here are its key features:

Functionality: As a basic control positioner, it converts electrical input signals (e.g., 4–20 mA) into pneumatic output signals to actuate valves, ensuring accurate positioning based on process requirements.

Design: Built with a compact, robust structure, it is suitable for direct mounting on linear or rotary actuators, minimizing installation complexity.

Compatibility: Works with a wide range of valves and actuators, making it versatile for various industrial applications, including chemical, oil & gas, and power sectors.

Performance: Offers reliable operation with high precision, ensuring stable control even in moderate environmental conditions.

The 3730-3 is an advanced model in the 3730 series, distinguished by its HART protocol compatibility and enhanced diagnostic capabilities:

Communication: Supports the HART 7 protocol, enabling two-way digital communication with control systems for remote configuration, monitoring, and diagnostics. This reduces downtime and simplifies maintenance.

Functionality: Features full parameterization, allowing users to customize settings such as travel range, fail-safe positions, and linearity adjustments. It also includes advanced diagnostics to monitor performance and detect faults in real time.

Design: Like other 3730 series models, it is compact and designed for easy installation. It can be mounted on both linear (e.g., diaphragm actuators) and rotary (e.g., rack-and-pinion actuators) valves.

Performance: Offers high positioning accuracy (typically ±0.5% of full scale) and fast response times, making it suitable for demanding applications that require precise control and real-time data integration.

Environmental Resistance: Built to withstand harsh industrial environments with a protection rating of IP65, ensuring dust and water ingress protection. It also meets explosion-proof standards for use in hazardous areas.
