VSP pressure sensor

For oil-pressure applications

As one of our smallest pressure sensors, the VSP stands out in particular for its robust and submersible design, which makes it a reliable solution for any oil-pressure application in motor vehicles and commercial vehicles.

Measurements of absolute or relative pressures in a rated pressure range up to 600 bar are possible with the VSP. Its specially developed evaluation electronics permit highly accurate and stable measurements at temperatures up to 150 °C, even under harsh conditions. In addition, the VSP meets the high EMC and ESD requirements that apply in the automotive industry.

The automatic assembly machines can be flexibly adjusted, allowing individually tailored production of the sensor and optimum adaptation to the respective application.
