PS16 automotive pressure transducer - wps500x analog| ROTKEE

100$

The sensor measures cylinder compression, intake manifold vacuum, back pressure. All these measurements can be made in one hit. These parameters allow detecting airflows from the combustion chamber, as well as determining the working phases of the valve timing. 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.

Pressure conversion response

Electrical protection:

- from the reverse polarity;

- from the ground fault of the sensor signal output;

- from supplying the voltage to the sensor signal output;

- the sensor case is not connected to the negative wire, so if the sensor is screwed into the spark-plug well and the negative power wire is accidentally connected to the positive terminal of the automotive battery, there won’t be a short circuit.

Video Lessons

Diagnosing a timing belt system with the help of a PS16 pressure sensor and automotive oscilloscope MT Pro, connecting the sensor to the engine, oscilloscope tuning, oscillogram recording while idle running, increased load and cranking. I’ll demonstrate all of this with an example of Seat Ibiza.

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 М14х1.25. If you need to connect the sensor to another threaded connection, use one of the proposed adapters.

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

The soft microphone cable with a dense shielding braid is used as a signal cable. BNC is used as a sensor-oscillograph connector. The power cable is insulated in soft silicone. Clips are used for connecting to the automotive battery.
