Marine oil pressure gauges designed to monitor pressure of oil in your engine and transmission. These oil pressure gauges are available with European and American resistance, in a wide range of Kus and Faria marine gauge styles.
Choosing between European and American resistance:A marine pressure sender uses resistance to operate the oil pressure gauge. The sender supplies the gauge with a resistance which the gauge then displays as a reading on the dial, but this can be either European or American resistance. A European resistance oil pressure sender has a low output at low pressure and as the pressure increases so will the resistance, while an American resistance pressure sender will have a high output at low pressure and the resistance will decrease as the oil pressure increases. For oil pressure gauges, European resistance gauges display the main reading in Bar, while American resistance gauges display the reading in PSI. It is important to match the gauge with the correct sender, as a mix of European and American resistance will cause your boat gauge to read backwards!
