Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ST150PG2SPGF is determined by the following critical parameters:

Primary Compatibility Criteria:

• Pressure range: 0-150 PSI nominal operating pressure
• Pressure type: Vented gauge configuration
• Output signal: 4 mA ~ 20 mA analog current
• Port connection: Male 1/4" NPT threaded interface
• Features: Amplified output with temperature compensation

Secondary Compatibility Criteria:

• Supply voltage overlap within specified ranges
• Accuracy specification suitable for industrial automation
• Operating temperature range compatibility with application environment
• Maximum pressure rating adequate for system overpressure protection

The IPSU-GP150-5 manufactured by Sensata-Cynergy3 meets all primary compatibility criteria and demonstrates functional equivalence for the ST150PG2SPGF in industrial automation applications.

Parameter Comparison

Engineering Selection Recommendations

For ST150PG2SPGF Replacement:

The IPSU-GP150-5 serves as a direct functional equivalent for applications operating within the following constraints:

1. Temperature Environment: Application operating temperature must remain within -20°C ~ 80°C. Systems requiring the full -40°C ~ 100°C range of the original ST150PG2SPGF cannot use this substitute without thermal management modifications.

2. Overpressure Protection: Maximum system pressure must not exceed 300 PSI. Applications with potential overpressure events beyond 300 PSI require alternative solutions, as the ST150PG2SPGF provides 450 PSI maximum pressure rating.

3. Supply Voltage: System power supply must operate within the overlapping range of 9.5V ~ 32V. Verify that existing power conditioning maintains voltage within this window.

4. Accuracy Requirements: The IPSU-GP150-5 provides superior accuracy (±0.25% versus ±1%), which is compatible with all applications designed for the original part.

5. Regulatory Compliance: Both parts maintain RoHS compliance. The IPSU-GP150-5 carries ROHS3 certification and is REACH unaffected, meeting current environmental regulations.

6. Connector Interface: The IPSU-GP150-5 features connector termination versus the original part's unspecified termination style. Verify connector compatibility with existing system wiring harnesses.

Frequently Asked Questions (FAQ)

Q: Can the IPSU-GP150-5 directly replace the ST150PG2SPGF in all applications?

A: Direct replacement is possible only when the application operates within -20°C ~ 80°C temperature range and maximum system pressure does not exceed 300 PSI. Applications requiring the full -40°C ~ 100°C range or higher overpressure protection require alternative solutions.

Q: What is the significance of the pressure type "Vented Gauge"?

A: Vented gauge pressure sensors measure pressure relative to atmospheric pressure through a vent port. Both the ST150PG2SPGF and IPSU-GP150-5 are vented gauge sensors, ensuring equivalent measurement characteristics in applications designed for this configuration.

Q: Are the 4 mA ~ 20 mA output signals identical between these parts?

A: Yes. Both sensors provide standard 4 mA ~ 20 mA analog current output, ensuring compatibility with existing signal conditioning and data acquisition systems designed for this output range.

Q: What does "Amplified Output, Temperature Compensated" mean for substitution purposes?

A: Both sensors include internal signal amplification and temperature compensation circuitry. This ensures that output signals remain stable across the operating temperature range and that signal levels are suitable for direct connection to industrial control systems without additional external amplification.

Q: How do the accuracy specifications affect component selection?

A: The IPSU-GP150-5 provides ±0.25% accuracy compared to the ST150PG2SPGF's ±1% accuracy. This superior accuracy is compatible with all applications designed for the original part and may provide improved measurement precision in control loops.

Q: What is the impact of the different maximum pressure ratings?

A: The ST150PG2SPGF withstands 450 PSI maximum pressure, while the IPSU-GP150-5 withstands 300 PSI. In systems with potential overpressure transients, the lower rating of the substitute may be insufficient. Verify system pressure relief settings and transient pressure profiles before substitution.

Q: Does the connector termination difference affect installation?

A: The IPSU-GP150-5 features connector termination, while the ST150PG2SPGF termination style is unspecified. Verify that existing wiring harnesses and connector types are compatible with the IPSU-GP150-5 connector interface before installation.

Q: Are both parts suitable for industrial automation applications?

A: Yes. Both the ST150PG2SPGF and IPSU-GP150-5 are specified for industrial automation applications and provide equivalent functional performance within their respective operating parameter ranges.
