Ashcroft 532B189-01 Dresser Movement Assembly

Ashcroft 532B189-01 Dresser Movement Assembly is a replacement movement for Ashcroft Dresser gauge bodies, identified as the 16.1 Dresser movement and listed as a spare part for Ashcroft 4080 and 4480 series gauges. This high-range movement is specified for pressure indications from 1,000 psi up to 20,000 psi and is designed to fit into existing 4080/4480 gauge assemblies, providing the sensing and indicator-driving function of the gauge without requiring a full instrument replacement. Used in industrial environments such as oil and gas, petrochemical processing, and power generation, it enables continued pressure monitoring where high range is needed and the gauge body remains compatible with Ashcroft's Dresser architecture. The 532B189-01 part number identifies the exact movement module to pair with the corresponding dial, case, and connection hardware, ensuring proper fit and alignment with standard Ashcroft connection interfaces.
