Abstract
This invention relates to a pressure transducer and more particularly to a pressure transducer having means by which the pressure transducer can be removed from a pressurized line without loss of line pressure. The pressure transducer is mounted in a housing, which is adapted to be releasably mounted on a bracket. The bracket is provided with a tubular needle valve coupling which is adapted to be connected to a pressurized line. The coupling normally keeps the pressurized line closed, but when the housing of the pressure transducer is mounted on the bracket, the needle valve in the coupling is automatically actuated, opening the pressure transducer to the pressure in the line.
