SAMSON 3730-210010 is a specific model of SAMSON 3730 series digital electric valve positioner, mainly used for regulating valve control in process control field. The following is a detailed introduction:
1. Core technical parameters and functions
Input signal and control accuracy
Support standard 4-20mA current signal input (two-wire system), with reverse protection function, minimum range of 4mA, static damage limit of 100mA.
Built-in microprocessor realizes high-precision adjustment, and the final control deviation is ≤1%, which is suitable for industrial scenarios with high precision requirements (such as chemical reactor flow control, oil pipeline pressure regulation).
Gas source and output pressure
The gas supply pressure range is ≤10bar, and the output pressure can be adjusted to 0.2-7bar, which is suitable for most pneumatic actuators.
Low steady-state gas consumption (<0.06 scfm) can reduce operating costs.
Stroke and compatibility
Applicable to linear or angular stroke valves, preset stroke range (e.g. 3.6-200mm) through DIP switch, and support multiple installation methods (e.g. NAMUR standard, VDI/VDE 3845 angular stroke bracket).
Can be directly installed on pneumatic actuators such as SAMSON 3277, reducing the cost of additional brackets.
Environmental adaptability
Operating temperature range - 20℃ to 80℃, protection level IP66, meet the needs of conventional industrial environments.
Some models (such as 3730-21xxxx) have ATEX certification (II 2G Ex ia IIC T6), suitable for potentially explosive environments.
