Procurement Notes
Verify the specific model suffix against official NOSHOK documentation to confirm the exact pressure type, output configuration, and process connection details. Ensure the selected variant matches the required system parameters, particularly regarding gauge versus absolute pressure requirements and electrical output specifications. Cross-reference the part number with the manufacturer's current product listings to validate availability and technical compliance before procurement.
Selection Notes
Select this transmitter when a compact solution with high accuracy and fast response is required for low-pressure industrial environments. The choice depends on matching the 0-30 PSI range to the application needs and confirming compatibility with the existing analog signal infrastructure. Consider the physical installation constraints related to the 1/4 NPT fitting and the electrical requirements for the two-wire loop power supply.
Part Context
This component belongs to the NOSHOK PT20 series of general-purpose pressure transmitters. The series is designed to replace older models like the 300 series, offering improved performance metrics such as enhanced accuracy and faster response times. The PT20 line is widely used in industrial settings where reliable pressure data acquisition is critical for system operation and safety.
Replacement Considerations
The PT20 series is documented as a replacement for the NOSHOK 300 series. Verify that the legacy 300 series unit being replaced has compatible mounting dimensions and electrical interfaces. Confirm that the new PT20 model's output signal and pressure range align with the existing system design to ensure seamless integration without requiring significant circuit modifications.
