  • Pressure sensors with plugs for cold weather protection and methods for manufacturing the plugs
    Patent number: 10488289
    Abstract: A pressure sensor including a housing with a sensing element therein. A communication passageway is formed in the housing. The sensing element is in fluid communication with an outside of the housing through the communication passageway. The pressure sensor is further provided with a compensating structure, so that when a contact force is increased due to occurrence of a volume expansion of a liquid passed into the housing through the communication passageway, the compensating structure is used to compensate the volume expansion. A plug may also be used with the pressure sensor. The pressure sensor is such that when the liquid within the pressure sensor has an increased volume due to being frozen, such increased volume can be compensated, so as to prevent the components of the pressure sensor from being damaged.
