047841 - Miller Mechanical Coolant Temperature Gauge 100-250 F

Precise Thermal Monitoring for Miller Equipment

The Miller 047841 Mechanical Temperature Gauge is a critical component for maintaining the health and longevity of your engine-driven welding equipment. Designed specifically for the rigorous demands of industrial environments, this gauge provides an accurate readout of engine coolant temperatures ranging from 100°F to 250°F. As a genuine Miller OEM part, it ensures perfect compatibility and reliability when replacing worn or broken gauges on your existing machinery.

Unlike electrical gauges that depend on the machine's power system and sensors, this mechanical gauge operates independently, offering a robust solution that is less susceptible to electrical faults or wiring issues. The direct mechanical linkage provides real-time feedback on the thermal status of your engine, allowing operators to detect potential overheating issues before they result in catastrophic engine failure or costly downtime.

Installation is straightforward, designed to fit standard panel cutouts found on compatible Miller generators. The clear, high-contrast dial face is easy to read, even in bright outdoor conditions or dimly lit workshops. Whether you are performing routine maintenance or repairing a specific fault, trusting genuine Miller parts like the 047841 gauge ensures your equipment continues to perform at factory specifications.
