193231 - Miller Coolant Temp Sensor 300F 1/2 NPT

Reliable Thermal Monitoring for Welding Systems

The Miller 193231 Sender, Coolant Temp 300 Degree F 1/2-14 NPT is a critical component designed to maintain the operational integrity of your high-performance welding equipment. In the world of industrial welding, particularly with water-cooled TIG and MIG systems, thermal management is paramount. This genuine Miller Electric OEM part serves as the vigilant guardian of your cooling system, accurately monitoring coolant temperatures to prevent catastrophic overheating events that could damage torches, power sources, or pumps.

Engineered to withstand the harsh environments typical of fabrication shops and manufacturing plants, this sender is rated for temperatures up to 300 degrees Fahrenheit. This high thermal ceiling ensures that the sensor remains functional and accurate even under extreme duty cycles where coolant temperatures can rise significantly. The unit features a standard 1/2-14 NPT (National Pipe Taper) thread, a widely used specification in fluid power systems, ensuring a tight, leak-proof seal when installed correctly into the cooling manifold or reservoir.

Genuine OEM Quality

When replacing internal components of sophisticated welding machinery, utilizing genuine Original Equipment Manufacturer (OEM) parts is essential. The Miller 193231 is manufactured to the exact specifications required by Miller welding machines. Unlike aftermarket generic sensors which may have varying resistance curves or thread tolerances, this OEM sender guarantees correct calibration with your machine's control board or temperature gauge. This ensures that the temperature data displayed or used for automatic shut-off protocols is precise and reliable.

Installation and Compatibility

This sender is designed for seamless integration into specific Miller cooling systems. While it fits a variety of models, we always recommend verifying fitment using your machine's specific serial number. The 1/2-14 NPT connection allows for straightforward installation using standard tools. Proper maintenance of your cooling system, including the replacement of faulty sensors, extends the lifespan of your equipment and reduces downtime associated with thermal failures.
