For a number of years, we've wrestled with a combination of
vague instructions and/or ol' mechanic's tales about using
high melting point solder on the pins of a pitot tube connector.

Thanks to the generous loan of his new 14v pitot tube, Bill
Crook made it possible to check this out.

After 2 hours of operation at 13.5 volts on the bench, a
thermocouple on the solder joints of the connector rose
to 240 degrees F, about 200 degrees lower than the melting
point for the solder.

Ordinary 63/37 solder is entirely suitable for making
these joints.

Thanks Bill. Your pitot tube is in the mail.

What make and model was the pitot tube?

Aero Instruments. A PH-502-12 I believe.
