The Type 3730 electro-pneumatic positioner series is a reliable and versatile solution designed to meet the demands of a wide range of industrial applications. This positioner series offers a variety of different models to ensure compatibility with any process requirements and user needs. Two of the most basic control positioners in the range are the 3730-0 and 3730-1.
The 3730-2 positioner model features full function parameterization and advanced diagnostics, which take the capabilities of this series to the next level. In addition, SAMSON introduces communication protocols such as HART (3730-3), Profibus (3730-4), and Foundation Fieldbus (3730-5) beyond the 3730-2. Full function parameterization includes the option to characterize the reference variable, travel range, characteristic (e.g. linear and equal percentage), and performance characteristics (e.g. PID control coefficients). Advanced diagnostics complement this feature by offering enhanced functions such as 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.
The Electropneumatic positioner with HART® communication is a versatile device designed for attachment to linear actuators according to IEC 60534-6, VDI/VDE 3847, or SAMSON integral attachment. It is also compatible with rotary actuators according to VDI/VDE 3845 and double-acting actuators with Type 3710 Reversing Amplifier.
This high-performance positioner features simple one-knob, menu-driven operation, and can be configured with a computer over the SSP interface using the TROVIS-VIEW software. It boasts a configurable automatic start-up function, thanks to four different initialization modes, and also has integrated EXPERTplus diagnostics for control valves.
The SAM DIGITAL READY positioner comes with a calibrated travel sensor without gears that are susceptible to wear, and a sub (substitution) initialization mode that allows the device to be started up in case of emergency whilst the plant is running without having to change the valve position. All parameters are saved in non-volatile EEPROM, and the device also has a two-wire system with small electrical load of 410 Ω.
Other features of this device include an adjustable output pressure limitation, an adjustable tight-closing function, automatic zero monitoring, an integrated temperature sensor and operating hours counter, and two standard programmable position alarms. It also offers self-diagnostics and messages as condensed state conforming to NAMUR Recommendation NE 107, issued over a fault alarm contact or optional analog position transmitter. Moreover, it comes with a DTM file available for integration into FDT frame applications according to specification 1.2.
The Electropneumatic positioner with HART® communication is housed in either a die-cast aluminum or stainless steel housing, and it can be attached to a variety of actuators. The positioner is designed for any desired mounting position but not suspended mounting.
This positioner features an easy-to-read display that can be viewed from any mounting position thanks to rotatable reading direction. It has preset parameters, and only values deviating from the standard need to be adjusted. This feature makes it easy to use and reduces the time required for configuration.
The Electropneumatic positioner with HART® communication also has an integrated EXPERTplus diagnostics system for control valves, thus providing users with real-time information on the status of their valves. This is all made possible by the positioner's innovative one-knob, menu-driven operation system, which allows for easy and quick configuration of the device.
The Electropneumatic positioner with HART® communication is an advanced positioner that comes with an array of features that make it easy to use and versatile. Its compact design and die-cast aluminum or stainless steel housing make it suitable for use in a wide variety of applications, and its ability to be attached to a variety of actuators makes it a versatile solution for all types of control valve applications.
This positioner is ideal for any industrial environment and is designed to work with many different types of control valves. It is easy to install and configure, thanks to its simple one-knob, menu-driven operation system, and can be configured with a computer over the SSP interface using the TROVIS-VIEW software.
The Electropneumatic positioner with HART® communication comes with a number of other advanced features, including integrated EXPERTplus diagnostics for control valves, a sub (substitution) initialization mode, and automatic zero monitoring. It also has self-diagnostics and messages as condensed state conforming to NAMUR Recommendation NE 107, issued over a fault alarm contact or optional analog position transmitter.
