The SM-AIT accurately measures the air intake temperature of any intake manifold. This is ideal for intercooler, or aftercooler applications. Any K-Type thermo couple is compatible. Up to 32 Sensor Modules can be daisy chained together in the PLX iMFD system and can be connected to any PLX Multi Gauge through the digital serial output port. The Air Intake Temperature Sensor Module can also be used as a stand alone unit capable of interfacing with 3rd party hardware where both the digital output and analog output are available simultaneously. The SM-AIT has a temperature measurement range of 32 - 631 degrees Fahrenheit or 0 - 333 degrees Celsius.
