A drill bit may comprise a bit body including an electronic housing, one or more electronics coupled within the electronic housing, a transducer housing coupled to the electronic housing, a first transducer seated in the transducer housing, a first pressure tube extending through the bit body and coupled to the transducer housing, and a floating ball in the first pressure tube. A method may comprise allowing a drilling fluid to move through a first entrance and into a pressure tube formed in a bit body of the drill bit, allowing the drilling fluid to exert a force on a floating ball placed within the pressure tube, allowing the floating ball to transmit the force to a fluid placed within the pressure tube on an opposing side of the floating ball from the drilling fluid, and measuring pressure of the fluid with a first transducer.
