RIFE Sensors Surface Mount Temperature Sensor for 1/4" Bolt - DTM Connector Designed for high-performance applications where traditional liquid-based sensing isn’t an option or to be used in conjunction. The RIFE Sensors Surface Temperature Sensor delivers reliable, accurate readings in dry environments. This sensor bolts directly to the surface of the component you want to measure and captures metal surface temperatures, making it ideal for cylinder heads, intake manifolds, dry blocks, and other areas. Traditional surface sensors suffer from delayed and inaccurate readings caused by long electrical leads. Our design maximizes thermal conductivity, offering ultra-fast response times for precise, real-time readings. This can be used to input cylinder head temperature as the coolant input in your ECU or datalogger. Key Features: Bolt-down style for 1/4" bolt Deutsch 2 way DTM connection Design for extremely fast temperature readings Temperature Range -20 to 275°F Easy Installation No coolant required: Perfect for dry-block applications, air-cooled systems, or any other surface mount temperature requirements.

While we diligently attempt to source all US electronic components, we have not been able to source everything domestically.
