Key Parameters

Substitute Part Grouping Explanation

Substitution of the MG-750-A-MD-R is determined by strict equivalence across the following critical parameters:

Pressure Specifications: Operating pressure rating of 750 PSI and maximum pressure rating of 2250 PSI must be maintained to ensure sensor functionality within the specified measurement range.

Output Characteristics: The combination of Wheatstone Bridge transducer technology with 4-20 mA analog output and LCD display output is essential for system integration and signal compatibility.

Accuracy and Compensation: ±0.25% accuracy with temperature compensation ensures measurement reliability across the operating temperature range of -10°C to 60°C.

Electrical Interface: 12V supply voltage and output signal specifications must match to prevent circuit incompatibility.

Mechanical Interface: Male 1/4" NPT threaded port configuration ensures physical compatibility with existing system plumbing and manifold connections.

Compliance Status: RoHS compliance is required for regulatory adherence in industrial automation applications.

The MG-750-A-M12-R qualifies as a substitute part based on equivalence across all critical parameters listed above.

Frequently Asked Questions (FAQ)

Q: Can the MG-750-A-M12-R directly replace the MG-750-A-MD-R in existing installations?

A: Yes. The MG-750-A-M12-R is functionally equivalent across all critical parameters including pressure rating, output type, accuracy, supply voltage, and mechanical interface. Direct substitution is supported without system modification.

Q: What is the difference between the MG-750-A-MD-R and MG-750-A-M12-R model designations?

A: The model designations reflect different packaging or connector configurations within the same sensor family. Both parts deliver identical pressure measurement performance and output characteristics. The specific difference in designation (MD-R versus M12-R) relates to the physical package or termination style, not to functional performance.

Q: Are there any compatibility concerns with the 1/4" NPT port configuration?

A: No compatibility concerns exist. Both the main part and substitute maintain the same Male 1/4" (6.35 mm) NPT threaded port configuration, ensuring mechanical compatibility with existing manifold connections and plumbing interfaces.

Q: Does the MG-750-A-M12-R require recalibration when substituted for the MG-750-A-MD-R?

A: No recalibration is required. Both parts maintain identical ±0.25% accuracy specifications and temperature compensation characteristics across the -10°C to 60°C operating range. System calibration remains valid upon substitution.

Q: What is the supply voltage requirement for the MG-750-A-M12-R?

A: The MG-750-A-M12-R requires 12V supply voltage, identical to the MG-750-A-MD-R. Existing power supply connections and circuit designs require no modification.

Q: Is the MG-750-A-M12-R RoHS compliant?

A: Yes. The MG-750-A-M12-R is RoHS compliant, maintaining regulatory compliance status equivalent to the MG-750-A-MD-R for industrial automation applications.
