Description
SAMSON Type 3730-5 FOUNDATION Fieldbus Positioner is a smart electropneumatic positioner for linear or rotary pneumatic control valves using FOUNDATION Fieldbus communication. SANTAN supports model confirmation and quotation for new projects, maintenance replacements and engineered packages.
Values below are transcribed from the linked current SAMSON data sheet. Broad family ranges must not be treated as the limits of every order code; final selection depends on the complete configuration and process conditions.
Verified technical specifications
| Linear valve travel | 3.6 to 300 mm, attachment-dependent |
|---|---|
| Rotary opening angle | 24 to 100 degrees |
| Communication | FOUNDATION Fieldbus; IEC 61158-2 bus-powered interface |
| Supply air | 1.4 to 7 bar / 20 to 105 psi |
| Degree of protection | IP66 / NEMA 4X |
| Characteristic deviation | <= 1% |
Engineering selection checklist
| Process duty | State the fluid or gas, normal and upset conditions, and whether the duty is throttling, mixing, diverting or isolation. |
|---|---|
| Sizing basis | Provide normal, minimum and maximum flow plus upstream and downstream pressure; valve sizing must be checked for the actual service. |
| Mechanical configuration | Confirm nominal size, pressure class, body and trim materials, end connections, packing or bellows requirements. |
| Actuation and fail action | Confirm actuator type, available air supply, required fail-open or fail-close action, and accessory mounting. |
| Documentation | Request the exact SAMSON data sheet, dimensional drawing and configuration-specific approvals for the ordered code. |
Industry application guidance
The Type 3730-5 is relevant to digital valve positioning on foundation fieldbus process-control networks. Before ordering, engineers should review pressure-temperature limits, noise, cavitation or flashing risk, materials compatibility, actuator sizing and applicable project documentation.
