  • Patent number: 11597065
    Abstract: Pressure gauges according to this invention provide pressure measurement on all brands of crimping tools, including 6-Ton D3 tools. In particular, this design eliminates the need to remove the tool crimp head to measure the pressure of the crimping tool. Additionally, this design eliminates the need to install additional dedicated fixtures on the crimping tool to measure the ram pressure. This design incorporates a self-centering profile to avoid side-loading when mounting the pressure gauge in the crimping tool. The dial indicator on pressure gauges of this invention captures and holds the maximum pressure reading with the use of a simple manual lever. The lever can be easily reset for the next pressure reading. Pressure gauges according to various embodiments of this invention include dual piston pressure sensors. Additionally, pressure measurement is accomplished with a simple hydro mechanical manometer display.
