Aim Fuel Pressure Sensor 1/8 NPT 0-15 PSI

The Aim 0-15 PSI Pressure Sensor is available in 1/8 NPT and is fitted with a 4-pin 719 male binder connector to suit Aim loggers, dash loggers, lap timers and dash displays. Many aspects affect various engine pressures, so knowing your engine has the correct amount of pressure is paramount to longevity and performance.

If there is a pressure change, incorporating a pressure sensor into your setup will allow it to be detected and signalled to prevent the worst. You can see through live telemetry about what’s happening as the sensor turns the physical force of fluid pressure into a predictable electrical signal that can be monitored to protect your engine.

The Aim Pressure Sensor is installed directly into the fluid or air line of the system being monitored. Inside the sensor is a sensitive internal component, typically a thin diaphragm.

As the system generates pressure, whether from a pump, a mechanical piston, or compressed air, that pressure forces the diaphragm to flex or bend. The sensor precisely measures the degree of this movement and converts that physical displacement into an electrical voltage signal:

• Low Pressure (0 PSI): The sensor outputs its minimum voltage, typically 0.5 Volts (V).
• High Pressure (15 PSI): The sensor outputs its maximum voltage, typically 4.5 Volts (V).

This is a linear scale. This means if the pressure is exactly halfway (7.5 PSI), the voltage will also be exactly halfway between 0.5V and 4.5V (which is 2.5V). This electrical signal is what the vehicle’s data logger or ECU (Engine Control Unit) translates back into a pressure reading for you to see.
