Conduit Connections
The conduit connections to the transmitter are threaded.
Options available are 1/2-14 NPT, M20 x 1.5, PG 13.5 and
G1/2. Housings with M20 x 1.5 threads are marked with “M20
x 1.5”. Two openings are available on the 3152 and 3153
transmitter housings for convenient installation. Close off the
unused opening with a compatible thread type stainless steel
plug. Use your plant-approved, qualified thread sealant on the
conduit connection threads.
IMPORTANT
For all 3152 and 3153 transmitters, install the conduit plug
(provided with the transmitter) in the unused conduit opening
per the torque values in
The 3154 has one conduit connection.
Use a qualified conduit seal at the conduit entry to prevent
moisture from entering the terminal side of the housing during
accident conditions. Certain option codes provide a factory-
installed, qualified electrical connector. To prevent excessive
mechanical stress during seismic disturbances, support the
conduit/connector cable near the transmitter. Install the
conduit seal in accordance with the manufacturer’s
instructions or use the procedure in this section.
