I am in the automotive performance world, and after much experimentation I realized that standard original engine manufacturer IAT and temp sensors were slow, unresponsive, and flawed by design. Most often they were made for longevity and came incased in heavy plastic or metal cages. The cages themselves skew the readings of the sensors, because the casings themselves absorb heat and emanate the heat onto the sensors that they are protecting, which greatly affects the responsiveness of the actual temperature occurring.
I found the above sensor packaged as an "external sensor" in available digital automotive thermostat/compass units (branded by Roadpro and TypeS) which plugged into the side of the unit via a tiny jack. They came incased in a protective oval plastic casing which had the word "sensor" stamped on it, and adhesive tape on one side. I pealed off the tape, removed the casing, and discovered that the bare sensor probe was very fast, accurate, excellent recovery, and needed almost no smoothing in my calibration software I designed. This sensor was late replaced by newer and probably cheaper probes that did not have this tiny board.
This sensor was also fairly available on household indoor/outdoor thermostat units.
I began to test my air-to-water intercooler systems using this sensor rather than automotive IAT sensors and datalogging... much more indicative of actual temps. I used this particular sensor in my intercooler outlet for the past five years, independent of any engine IAT's or functions.
I want some help identifying it, and sourcing more if possible. Any help appreciated!
Thanks,
