Pressure Sensors Transducers Procurement Notes

Verify that the specified pressure range of 2000 psig aligns with the maximum operating pressure of the target application, ensuring it remains within the safe working limits. Confirm that the 1/2-14 NPT thread size matches the existing process connection interface to ensure proper mechanical sealing. Check that the required power supply voltage falls within the 10.5 to 45 VDC input range for stable operation. Ensure environmental conditions do not exceed the specified temperature limits for both the process media and ambient surroundings.

Pressure Sensors Transducers Selection Notes

Select this model when high accuracy and durability are required for medium-to-high pressure applications. The 316L stainless steel construction makes it suitable for corrosive media compatible with stainless steel. Consider the IP67 rating for installations exposed to dust or temporary water immersion. The 4-20 mA output is ideal for integration with standard PLCs and DCS systems. Evaluate the need for additional certifications if used in hazardous areas, as standard models may not meet explosion-proof requirements without specific ordering options.

Pressure Sensors Transducers Part Context

This transmitter belongs to the NOSHOK PT40 series, which is engineered for general industrial process applications. The series is known for its rugged design and cost-effective performance. The PT40 line typically offers various pressure ranges and process connections to suit different industry needs. This specific configuration represents a common setup for hydraulic and pneumatic systems requiring precise pressure feedback.

Pressure Sensors Transducers Replacement Considerations

When replacing legacy units, verify compatibility with existing mounting brackets and wiring configurations. Direct replacements should match the original pressure range, output signal type, and process connection thread. If upgrading, consider models with improved accuracy or digital communication protocols like HART, provided the control system supports them. Ensure the replacement part maintains the same material compatibility with the process fluid.
