Sender resistance values (merc compatible)
Now that I'm in gauges I have found the following resistance levels for gauges on ohms. The reading is in ( ) :
Gauge low high mid
Fuel 240 (E) 33 (F)
Oil Press 153 (20) 67 (60)
Trim 167 (up) 10 (DN) 44 (1/2)
Oil Temp 362 (100) 28.5 (240)
Water T 230 (131) 64 (200)
There are other systems out there, but these are merc std.
Also most people to not use the proper tube for high speed pitot speedos. Here are the following PSI vs reading:
40 mph 21.84 psi
50 mph 34.13 psi
70 mph 66.89 psi
90 mph 110.56 psi
Just FYI
