Abstract
A temperature compensating or offsetting magnetically coupled pressure sender comprises a pressure responsive element coupled to a rotating permanent magnet via a temperature sensitive element. The sender is intended to relay a pressure reading from within sealed vessels, including vehicle tires, without requiring penetration the wall of the vessel. In vehicular applications, the recommended pressure is usually stated for “cold” tires. Operating a vehicle heats up its tires and increases their pressure, which may produce a misleading indication. Pressure senders described in this invention have temperature compensating or offsetting elements built in to the pressure senders so that the indicated pressure is always referenced to a “cold” tire. Spiral or helical metallic strips or elastomeric members may be employed as the temperature compensating or offsetting elements.
