About this item

  • One wire to sensor ground and one wire to sensor signal
  • Wire strip length is 0.175 inches to 0.200 inches
  • Thread size: 1/8 inches
  • Operating temperature: sensor tip -40C to 200C, connector -40C to 150C


This product has sensor performance specifications with accuracy of more than 2 degree centigrade / 3.6 degree Fahrenheit and operating temperature of - 40 Celsius to 200 Celsius / -40 Fahrenheit to 392 Fahrenheit. The dissipation constant is 12 megawatt per degree centigrade and the ratio, at a specified ambient temperature, of the change in the power dissipation of the sensor to the resultant temperature change of the Thermistor. The test medium is silicone oil and thermal time constant is 10 sec. The time required for the sensor to achieve 63.2 per cent of its steady state value when subjected to a step change in ambient temperature [Tc= (Tf-Ti) x63.2%+Ti]. Sensor body material used is brass, thread: 1/8 inches -27 PTF, hex size is 1/2 inches, installation torque: 13.5Nm / 10 feet-pounds, weight of 12.2 grams, supply current: 5 Volt DC, electric termination: connector includes mating connector, pins and pin lock.

Works with TunerStudio / MegaSquirt, as an oil temperature sensor IF you have the correct files. I have worked out the files with the TunerStudio folks in this thread:http://www.msextra.com/forums/viewtopic.php?f=122&t=58859The sensor seems well built and I have not had any trouble with it. I used it to measure the oil temperature in an aircooled VW bug, after making a custom fitting.

It has a datasheet so it's nice an easy to use/map anywhere. Good quality product. Temp/resistance values have a slight curve. Check out the data sheet to make sure it works for you.

My Blue Supra is not my daily so it doesn't get driven but only a handful of times a year. I feel the sensor should have lasted longer than it did..(used for coolant temp)

Great product, comes with 3 crimp connectors and a new connector. Price is high for just the sensor and connector.

Did not come with electrical pins shown in the bottom left of the picture

Kind of expensive, but if you need a 1/8" NPT 2-wire temperature probe, then this was pretty much the only one I could find. I haven't tested the calibration, but it's accurate at ambient temp and is at least not wildly inaccurate at 100C.

AEM is the only brand to have this much quality.

Works as advertised.

Calibrated based upon aem 30-2012. At ambient temp it is 20deg c lower then all other temp sensors in the engine bay. For the price do not buy it.
