Abstract
A pressure sensor for a vehicle includes a housing, in which at least one sensor unit is arranged. The at least one sensor unit determines a pressure difference between a pressure at a measurement connection point and atmospheric pressure. The at least one sensor unit senses the atmospheric pressure at at least two reference pressure bores. The disclosure further relates to a braking system for a vehicle, having at least one such pressure sensor. A sensor dewatering means comprises a connection channel, which connects the at least two reference pressure bores to each other.

A pressure sensor for a vehicle, comprising:
- a housing;
- at least one sensor unit arranged in the housing and configured to determine a pressure difference between a pressure prevailing at a measurement connection and atmospheric pressure;
- at least two reference pressure holes, the at least one sensor unit sensing the atmospheric pressure at the at least two reference pressure holes;
- and
- a sensor drainage arrangement a connecting channel that connects the at least two reference pressure holes to each other.
A braking system for a vehicle, comprising:
- at least one brake booster;
- at least one brake circuit;
- and
- at least one pressure sensor comprising:
- a housing;
- at least one sensor unit arranged in the housing and configured to determine a pressure difference between a pressure prevailing at a measurement connection and atmospheric pressure;
- at least two reference pressure holes, the at least one sensor unit sensing the atmospheric pressure at the at least two reference pressure holes;
- and
- a sensor drainage arrangement having a connecting channel that connects the at least two reference pressure holes to each other.
