The Type 3730 electro-pneumatic positioner series is designed for general industrial applications. This series offers various model versions that cater to different needs of the end user or the process. The 3730-0 and 3730-1 are basic control positioners.
With the 3730-2, the positioner includes full function parameterization and advanced diagnostics. SAMSON offers communication protocols such as HART (3730-3), Profibus (3730-4), and Foundation Fieldbus (3730-5) above the 3730-2. Full function parameterization encompasses characterizing the reference variable, travel range, linearity and performance characteristics such as the PID control coefficients. Advanced diagnostics offer functions like status message logging, data logging, histograms for travel setpoint deviation and cycle counters. Drive signals for steady and hysteresis, end position trending, static characteristic, partial stroke testing, and full stroke testing are also included.
The SAM Digital Ready electropneumatic positioner is designed for attachment to linear and rotary actuators, providing precise control of valve positions in any desired mounting position (except suspended). The positioner features both die-cast aluminum and stainless steel housing options, and is compliant with IEC 60534-6, VDI/VDE 3847, and SAMSON integral attachment standards.
The positioner also includes an integrated EXPERTplus diagnostics system for control valves, with a simple one-knob, menu-driven operation and an easy-to-read display that can be rotated for optimal visibility. It can be configured with a computer via the SSP interface using the TROVIS-VIEW software, and features a variable automatic start-up with four initialization modes and calibrated travel sensor without gears susceptible to wear.
Additionally, the positioner includes a sub (substitution) initialization mode that allows it to be started up in case of emergency while the plant is running without having to change the valve position. It also has adjustable output pressure limitation, tight-closing function, and automatic zero monitoring, as well as an integrated temperature sensor and operating hours counter.
The SAM Digital Ready positioner features two standard programmable position alarms, self-diagnostics, and messages that conform to NAMUR Recommendation NE 107. It also has a fault alarm contact and optional analog position transmitter, with a DTM file available for integration into FDT frame applications according to specification 1.2.
