<p>A pressure measuring device will measure pressure in a subsea tubular member. The device includes a stationary unit mounted to the exterior of the tubular member and a movable unit that will be lowered into position next to the stationary unit whenever pressure is to be monitored. The stationary unit has a strain gage which will monitor pressure by measuring strain in the tubular member. The stationary unit has a light emitter which will emit pulses corresponding to pressure measured. The stationary unit has a photocell which will receive a light beam from the movable unit. The light beam and photocell provide power for the stationary unit. The movable unit has a receiver which receives any light pulses from the light emitter and correlates them to a pressure measurement.</p>
