Excellent add!
Note:
This older style and larger oil pressure sensor uses a flexible tube/bellows to push/pull a wiper/contact across a wire wound resistor. This results in a resistance of 3-160 ohms and only works with older analog gauges. From my experience, they are not accurate and don't work well for long, as they wear out quickly due to the constant moving of the "wiper"
Today, most pressure sensors are all electronic, temperature compensated and provide a voltage of 0.5 volts for 0 psi, to 4.5 volts for 150 psi. (or 4.5v @ 100 psi)
As you can imagine, the electronic pressure sensor are more accurate, quicker to respond and durable.
