Emerson 396VP, 398VP, 397 instruction manual Section

Metal Process Connector PN 23166-xx (xx = 00 for 316 SST and xx = 01 for tita- nium) can be used for insertion or sub- mersion mounting of Models 396VP or 398VP sensors in 1-inch fittings.

The metal process connector gives the sensor var- ious insertions depths, depending on where the user locates the compression fitting. Also the threads can be switched to face the cable end of the sensor for connection to submersion pipes.
