The Type 3730 electro-pneumatic positioner series is specifically designed for use in general industrial applications. This series boasts multiple model versions to cater to varying end-user and process requirements. The 3730-0 and 3730-1 positions make up the basic control positioners of the series.
The 3730-2 is the first model version to include full function parameterization and advanced diagnostics. Beyond the 3730-2, SAMSON integrates communication protocols like HART (3730-3), Profibus (3730-4), and Foundation Fieldbus (3730-5). Full function parameterization means users can specify the reference variable, travel range, characteristic, and performance characteristics like PID control coefficients. Advanced diagnostics, on the other hand, offer additional functionalities such as status message logging, data logging, and histograms, among others.
Some of the additional advanced diagnostics functions for the positioner series include features such as drive signals (steady and hysteresis), end position trending, static characteristic testing, partial stroke testing, and full stroke testing. With these advanced features on the 3730-2 and up, users can maximize their control capabilities and ensure optimum functionality for their processes.
The SAM DIGITAL READY Electropneumatic Positioner is designed for superior performance and reliability. It allows for attachment to various types of linear and rotary actuators, including double-acting actuators with Type 3710 Reversing Amplifier. Its die-cast aluminum or stainless steel housing ensures durability and longevity.
The positioner comes equipped with integrated EXPERTplus diagnostics, allowing for easy control of valves. The one-knob, menu-driven operation makes for simple and straightforward configuration, while the easy-to-read display can be rotated for use in any mounting position.
The positioner can be configured using a computer over the SSP interface, using the TROVIS-VIEW software. It also features variable automatic start-up with four different initialization modes, and calibrated travel sensors that are not susceptible to wear.
Other features of the positioner include adjustable output pressure limitation, adjustable tight-closing function, automatic zero monitoring, integrated temperature sensor and operating hours counter, two standard programmable position alarms, self-diagnostics, and condensed state messages, all conforming to NAMUR Recommendation NE 107. Additionally, the positioner's DTM file allows for integration into FDT frame applications according to specification 1.2.
