MGL LM335 temperature sensors. Choose either the basic sensor or the one with aluminium cover.


These two OAT sensors use the LM335 semiconductor. 

The basic black sender is the ambient temperature probe included as standard with all our instruments that support ambient temperature measurements.

The OAT sensor with aluminium cover is a good looking option if you want to mount the sensor on the outside of the aircraft. The sensor is mounted in an 8mm hole and the unit comes with a nylon retaining nut and two nylon washers. 

This basic sensor is also a popular choice if you need to make your own coolant or oil temperature probes. In this case you use the brass body of an existing probe that fits your engine's requirements. Open, or drill out this probe and remove everything that is inside (so you end up with an empty brass body with the correct dimensions and thread). Then insert the sensor tip and ensure that the body of the tip contacts the brass body (to ensure rapid temperature transfer ). Then use a oil resistant epoxy to seal the sensor inside the brass body.

Red wire goes to instrument, green to ground.
