Key Parameters

Substitute Part Grouping Explanation

Substitution of the MG-2000-A-MD-R is determined by strict equivalence across the following critical parameters:

Pressure Specifications: Operating pressure rating of 2000 PSI and maximum pressure rating of 6000 PSI must be maintained to ensure system safety and measurement accuracy within the original design envelope.

Output Characteristics: The combination of Wheatstone Bridge transducer technology with 4-20 mA analog output and LCD display functionality defines the sensor's signal interface. Substitute parts must provide identical output types to ensure compatibility with existing signal conditioning and display systems.

Accuracy and Compensation: ±0.25% accuracy with temperature compensation is required to maintain measurement reliability across the -10°C to 60°C operating range specified for industrial automation applications.

Electrical Supply: 12V supply voltage requirement must be preserved to ensure compatibility with existing power distribution infrastructure.

Mechanical Interface: Male 1/4" NPT threaded port configuration is a critical mechanical parameter that determines physical installation compatibility within existing pressure systems.

Pressure Type: Vented gauge pressure measurement type must be maintained for applications requiring atmospheric reference.

The MG-2000-A-M12-R is identified as a substitute part within the MG-MD series family, sharing the same manufacturer, pressure ratings, output specifications, accuracy, supply voltage, and temperature compensation characteristics as the original MG-2000-A-MD-R.

Parameter Comparison

Engineering Selection Recommendations

The MG-2000-A-M12-R is identified as the primary substitute for the obsolete MG-2000-A-MD-R based on the following engineering criteria:

Product Status: The MG-2000-A-M12-R maintains active product status with Amphenol SSI Technologies, ensuring ongoing availability, technical support, and supply chain continuity. The original MG-2000-A-MD-R is classified as obsolete, making the active substitute essential for new procurement and system maintenance.

Functional Equivalence: Both sensors share identical pressure ratings (2000 PSI operating, 6000 PSI maximum), output specifications (Wheatstone Bridge with 4-20 mA and LCD display), accuracy (±0.25%), supply voltage (12V), and temperature compensation characteristics across the -10°C to 60°C operating range.

Compliance Status: The MG-2000-A-MD-R is RoHS Compliant with MSL 1 rating. The MG-2000-A-M12-R is manufactured by the same supplier and represents an active product line continuation, maintaining equivalent compliance standards.

Pressure Type Consistency: Both sensors operate as vented gauge pressure instruments, preserving the atmospheric reference measurement principle required for the original application.

Selection of the MG-2000-A-M12-R as a substitute is supported by complete functional and electrical equivalence across all specified parameters, combined with active product status and manufacturer continuity.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the MG-2000-A-MD-R and MG-2000-A-M12-R?

A: The primary difference is product status. The MG-2000-A-MD-R is obsolete, while the MG-2000-A-M12-R is an active product.
