Brake Pressure Sensor
This brake pressure sensor is specifically designed for measuring the high pressures in automotive braking systems. It is extremely robust and resistant to brake fluids, mineral oils, water and air.

Design and function
The sensor is specially designed to measure absolute pressure in gasoline direct injection applications. This sensor is also compatible with other kind of fluids e.g. Diesel, engine oil, transmission oil or brake fluid. The sensor uses a thin layer technique to achieve high accuracy pressure measurements. The stainless steel measuring cells with piezoresistive bridges are hermetically welded with stainless steel pressure ports. The internal reference ensures ambient pressure independent measurements.
The main benefits of this sensor are its high accuracy, its wide measurement range and its robust and compact design.
Installation
Extreme care must be taken installing any product that connects to the braking system of a car - we take absolutely no responsibility for installation, and recommend that if in any doubt you employ a professional!
If the sensor has been supplied by Race Technology with a cable attached then wires from the sensors are:
- Red - Connect to the +5v reference output from the DL1/DL2/DASH2
- Black - Connect to ground (0v) on the DL1/DL2/DASH2
- White - Signal output from the sensor, this can be connected to any of the analogue inputs on the DL1/DL2/DASH2
