1. A system comprising:
a sensor assembly;
a wellhead flange sized to receive the sensor assembly;
a seal positionable between the sensor assembly and the wellhead flange for sealing the wellhead flange from an external environment;
an inner coil positionable within the sensor assembly, wherein the inner coil is wirelessly couplable with an outer coil positionable around the sensor assembly for transmitting data or power with respect to the wellhead flange, and wherein the inner coil and the outer coil form a transformer with a non-ferromagnetic coupling; and
a sensor positionable in a through bore of the wellhead flange, the sensor couplable with the inner coil for transmitting and receiving data or power with respect to the wellhead flange.
