The RAS-RAM consists of two components: the RAS or Remote Access Sensor and the RAM, the Remote Access Module. During an outage, the RAS is affixed to the test point and attached to a cable that will run to a location where it can be accessed by an inspector. Using an Ultraprobe, the Inspector attaches the BNC fitting of the cable to the RAM, which is plugged into the front end of the instrument, just as with any other module. For multiple test points, a junction box is installed to keep the cable connections ready for the inspector.
This approach is becoming very popular with our users. In one instance a food processing plant has a number of motors that cannot be accessed since they are in the processing area and the FDA did not want anyone entering the area due to the possibility of contamination. The RAS-RAM system was installed on the motor bearings and the cables were coded so that inspectors would know the identity of the test point they were monitoring. These bearings were then included in the inspection schedule as part of a route and inspected routinely with their Ultraprobe.This is but one example. Think of the possibilities in your plant. Anything you would like to test with your Ultraprobe where access is an issue can be considered. This can be bearings, gearboxes or valves to name a few.
