ABSTRACT:
A none intrusive pressure sensing device that clamps on to a pressure line and detects the internal pressure of the pressure line by detecting the resultant changes in the diameter of the pressure line. The clamp is held together by a fastener having a sensing element, such as a strain gage, that is able to detect the change in length of the fastener as the pressure line and the clamp expand and contract with the internal pressure of the pressure line.
