Aim Oil / Fuel Pressure Sensor 0-5 Bar

The Aim 0-5 Bar Pressure Sensor is available in M10 and -3 JIC (3/8-24 UNF) thread options 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 Oil / Fuel Pressure Sensor sits in the oil/fuel line. Inside it, there's a sensitive part (often a small sheet of material called a diaphragm). When the pump pushes the oil or fuel, the pressure makes this diaphragm flex or bend. The sensor measures exactly how much it bends. The pressure sensor then converts the pressure into voltage:

• Low Pressure (0 bar): The sensor might output a very low voltage, like 0.5 Volts (V).
• High Pressure (5 bar): The sensor outputs a high voltage, like 4.5 Volts (V).

This is a linear scale, meaning that if the pressure is halfway (at 2.5 bar), the voltage will also be halfway (around 2.5V). This electrical signal is what the vehicle’s data logger or ECU (engine computer) records.

To extend the length between your dash display/logger and the analogue sensor, you will need a 719-719 patch lead, available in various sizes from 0.5m to 4m. For most installations, you will likely need one of these patch leads. However, a 719-719 patch lead is also available for use with the EVO4, EVO4S and Channel Expansion.
