Electronic Timer Condensate Drain Valve for A...: 
Nitrile (NBR) O-Ring Assortment Kit, Metric, ...: Ingersoll Rand 38433546 is the temperature sensor that reports the compressor temperature to the controller, which trips the machine before it overheats. It is used on Ingersoll Rand rotary screw air compressors. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

High temperature trips or a sensor fault
A failed sensor reads open or short, or reports a temperature far from the real one, so the controller trips the compressor or shows a sensor fault. Check the plug and wiring first.
Compressor stops on temperature with a cool machine
If the compressor shuts down on high temperature but the oil and cooler are fine, a drifting sensor is the usual cause. Compare its reading with a thermometer at the same point.
Damaged cable or connector
A crushed lead or a connector that has taken oil or water gives erratic readings. Replace the sensor and route the new cable clear of hot pipes.
Fitting tips
Isolate power and let the compressor cool and vent before removing the sensor. Use a new sealing washer or thread sealant suited to the port, tighten on the hex only, and check the reading on the controller after start up.
