Abstract
An oilfield pressure gauge carrier for use in supporting pressure gauges on a string of pipe in a wellbore including an elongated carrier with a through bore and outer surface recesses for receiving one or more pressure gauges. A pressure gauge is attached to an outer surface for vertical movement in the event of an applied shock force and provided with spring damping devices at either end to absorb shock effects. A restricted flow passageway to the pressure gauge inhibits application of hydraulic surges to the pressure gauge.
