Abstract
Pressure sensors and their methods of use are described. In one embodiment, a pressure sensor may include: a tubular probe body; a capacitive sensor disposed at the distal end of the probe body; a lead electrically coupled to the sensor extending along an interior space of the probe body; and at least one support formed of a material having a relatively low dielectric constant disposed within the probe body to support the lead and space the lead away from an inner wall of the probe body. This may help to minimize shunt capacitance and changes in shunt capacitance due to radial movement of the lead. In other embodiments, a pressure sensor may include a channel formed in a wall of the probe body, a temperature sensor disposed at a distal end of the probe body, and a temperature sensor lead disposed in the channel and connected to the temperature sensor.
