3730-3 Electropneumatic Positioner with Hart Communication
Product Description
3730-3 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. 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.

Advantages
High-precision Positioning: Achieves high-precision position control through advanced microprocessor technology, ensuring precise adjustment of valve opening, with an error correction accuracy of up to ±0.5%.
Energy Efficiency: Compared with the previous series, the air consumption is reduced by half, and the pneumatic control loop is more energy-efficient.
Strong Environmental Adaptability: With an IP66 protection level, it can adapt to harsh industrial environments such as high temperature, humidity, and corrosive gases.
Long Service Life: The non-wear electromagnetic drive structure extends the maintenance cycle by more than 30%.
User-friendly Operation: The single-knob button operation and multi-language display make parameter setting and configuration debugging easy. The variable automatic start and preset parameter design reduce the setup workload.
Modular Design and Expandability: Supports the integration of accessories such as reverse pneumatic amplifiers and limit switches, enhancing system flexibility. It also has certain compatibility with multi-axis collaborative automation systems (such as being modularly designed and compatible with EtherCAT communication protocol in some aspects).
Reliable Safety Performance: Certified by IEC 61508/SIL, and specifically designed for emergency shutdown systems, which can ensure safety in harsh industrial environments and emergency situations.
