pressure sensor 100 bar


The sensor measures pressure in intake and exhaust manifolds as well as compression and pressure in combustion chamber, while the diesel engine is on. These parameters allow detecting airflows from the combustion chamber as well as determining valve timing of the valve train and the fuel system. It is also possible to carry out measurements in other engine systems, within the working range of the sensor, such as fuel system, lubrication and cooling systems.

NB! The sensor and diagnostic technique are in the testing process.

Sensor construction

The sensor case is made of steel, which reliably protects it from possible mechanical damage and external electromagnetic noise. The coating is black zinc. Connecting thread is М10х1. Use one of the available adapters to connect the sensor.

The signal cable is connected to the sensor via a three-pin connector with a latch.
