Description : |
Remote alarm actuator / indicator (RAAI) which can be used with sand probe to indicate when erosion penetrates the probe. The RAAI may be mounted directly on the probe or may be mounted remotely to a tee type access fitting body which is connected to the probe. As a sand probe is exposed to the flow of a system, a hole is eventually eroded through the probe’s element. Once penetration has occurred, the system pressure travels through the sand probe body and into the RAAI Adapter Stem, which pushes out the End Knob to its extended position, revealing a red indicator on the RAAI Body Stem. |
