Lowdoller Motorsports | 0-500 PSI Pressure Sensor

Lowdoller Motorsports 0–500 PSI Pressure Sensor – 899 Series

Part Number: 8990500

Accurately monitor high-pressure systems with the Lowdoller Motorsports 0–500 PSI Pressure Sensor. Part of Lowdoller’s oil-filled silicon 899 Series, this sensor is designed for motorsport applications where dependable pressure data is essential for tuning, diagnostics and component protection.

Featuring a standard 0.5–4.5V analogue output, the sensor uses the same voltage scaling commonly supported by Holley, Haltech, FuelTech, Racepak, RPM and other popular EFI and data-logging systems. This makes it straightforward to integrate into a wide range of race-car electronics packages.

The heavy-duty stainless-steel body and 1/8-inch NPT thread provide a durable, compact installation suitable for harsh environments involving heat, vibration and fluid exposure. With a maximum range of 500 psi, the sensor is particularly well suited to monitoring automatic transmission and converter pressures.

EFI and Data-Logger Compatibility

The sensor’s 0.5–4.5V output scaling is compatible with many commonly used motorsport systems, including:

• Holley EFI
• Haltech
• FuelTech
• Racepak
• RPM data systems
• Other EFI, dash and data-logging systems with a compatible analogue input

The receiving system must be configured with the correct 0–500 psi calibration for accurate readings.

Important Installation Notes

A pre-wired sensor cable is not included and is available separately.

The sensor must be wired to the appropriate regulated supply, sensor ground and analogue input specified by the ECU, dash or data-logging manufacturer. Incorrect wiring or calibration may result in inaccurate readings or sensor damage.

For applications exposed to excessive vibration or pressure pulsation, remote mounting the sensor with a suitable hose may help protect the sensor and improve service life.

Why Monitor Transmission Pressure?

Transmission and converter pressure data can help racers evaluate hydraulic performance throughout a run. It can reveal pressure drops, unstable converter charge pressure, delayed gear engagement and other issues that may not be obvious from engine or driveshaft data alone.

When combined with engine RPM, driveshaft speed, gear position and transmission temperature, pressure data provides a clearer picture of how the complete driveline is operating.

Why Choose Lowdoller Motorsports Sensors?

Lowdoller Motorsports develops practical and cost-effective sensors for racers who need dependable data without unnecessary complexity. The 899 Series offers standardised outputs, durable construction and broad compatibility with leading motorsport electronics systems.
