Mounting with Drain Seal
If mounting the transmitter directly to the sensor assembly, use the process
shown in Figure 2-4. If mounting the transmitter apart from the sensor
assembly, use conduit between the sensor and transmitter. The transmitter
accepts male conduit fittings with
1
/2–14 NPT, M20 × 1.5 (CM 20), PG 13.5
(PG 11), or JIS G
1
/2 threads (M20 × 1.5 (CM 20), PG 13.5 (PG 11), or JIS G
1
/2
threads are provided by an adapter). Make sure only qualified personnel
perform the installation.
The transmitter may require supplementary support under high-vibration
conditions, particularly if used with extensive thermowell lagging or long
extension fittings. Pipe-stand mounting, using one of the optional mounting
brackets, is recommended for use in high-vibration conditions.
