NOTICE
This guide provides basic guidelines for Rosemount 0085 Pipe Clamp Sensor. It does not provide instructions
for configuration, diagnostics, maintenance, service, troubleshooting, explosion-proof, flameproof, or
intrinsically safe (I.S.) installations. Refer to the Rosemount 0085 Pipe Clamp Sensor Reference Manual for more
instruction. The manual and guide are also available electronically on Emerson.com/Rosemount.
If the Rosemount 0085 Sensor was ordered assembled to a temperature transmitter, see the appropriate Quick
Start Guide for information on configuration and hazardous locations certifications.

1.0 Location and orientation
The pipe clamp sensor should be mounted on the outside section of the pipe
where the process medium is in contact of the inside of the pipe wall. Ensure
that the pipe surface is clean of debris. The pipe clamp sensor should be
mounted in a secure position to ensure there is no rotational movement after
installation. To ensure ingress protection, the nut of the Rosemount 0085 Pipe
Clamp sensor can be tightened to compress the O-ring to form a seal. The nut
can be accessed and tightened by removing the sensor and the nipple union of
the extension. Refer to “Location and orientation” on page 3 for the location of
each part.
1.1 Horizontal orientation
Though the Rosemount 0085 Pipe Clamp sensor can be mounted in any
orientation for full pipe flow applications, the best practice is to mount the pipe
clamp sensor on the upper half of the pipe. Refer to Figure 2 for more
information.
Figure 2. Horizontal Orientation
1.2 Vertical orientation
The pipe clamp sensor can be installed in any position around the circumference
of the pipe.

1.3 Special considerations
Under most circumstances, the Rosemount 0085 Pipe Clamp Sensor can be
mounted in a direct mount configuration. Since heat from the process is
transferred from the pipe clamp sensor to the transmitter housing, if the
expected process temperature is near or beyond specification limits, consider
using a remote mount configuration to isolate the transmitter from the process.
Refer to the appropriate transmitter reference manual for temperature effects.

Figure 4. Pipe Clamp Sensor Assembly in Remote Mount Configuration
Wireless transmitters with external antennas allow for multiple antenna
configurations. All wireless transmitter should be appropriately 3 ft. (1 m) from
any large structure or building to allow clear communication to other devices.
Wireless transmitters with external antennas should be positioned vertically,
either straight up or straight down.

2.0 Install pipe clamp sensor
Select the area for pipe clamp sensor installation with the recommendations
outlined in “Horizontal orientation” on page 3. Mount the pipe clamp sensor on
the pipe and snug tighten the bolts. Ensure the sensor passes through the hole
of the pipe clamp and has direct contact between the sensor tip and pipe. Refer
to Figure 4 on page 5 for more information. Tighten the bolts to secure the pipe
clamp sensor to the pipe.

2.1 Install transmitter
See appropriate transmitter reference manual for sensor-transmitter
installation. Refer to Figure 7 for sensor lead wire terminations.

2.2 Commission transmitter
See appropriate transmitter reference manual for transmitter commissioning
instructions.
3.0 Installing optional accessories
3.1 Corrosion protection inlay
The corrosion protection inlay provides a layer of protection to help minimize
the possibility of dissimilar metal corrosion between the pipe clamp and pipe.
The inlay is installed in between the pipe clamp and the pipe. Ensure the sensor
is clearing the hole in the protection inlay after installation. Refer to Figure 8 for
more information.

3.2 Replacement sensor
The spring loaded sensor can be ordered for replacement using the Rosemount
0085 Pipe Clamp Sensor Product Data Sheet.
Use the following steps to replace the sensor.
1. Loosen and remove the original sensor from the extension of the pipe clamp.
2. Add pipe compound or PTFE tape (where local piping codes allow) to the
threads of the new sensor.
3. Insert the new sensor into the extension of the pipe clamp sensor and ensure
the sensor tip passes through the hole of the pipe clamp. Refer to Figure 6 for
more information.
4. Screw in the sensor and tighten to 24 ft-lbs of torque.

4.0 Rosemount X-well™Technology considerations
Rosemount X-well Technology is for temperature monitoring applications and is
not intended for control or safety applications. It is available in the Rosemount
3144P Temperature Transmitter and 648 Wireless Temperature Transmitter in a
factory assembled direct mount configuration with a Rosemount 0085 Pipe
Clamp Sensor. It cannot be used in a remote mount configuration.
Rosemount X-well Technology will only work as specified with factory supplied
and assembled Rosemount 0085 Pipe Clamp silver tipped single element sensor
with an 80 mm extension length. It will not work as specified if used with other
sensors. Installation and use of incorrect sensor will result in inaccurate process
temperature calculations. It is extremely important the above requirements and
installation steps below are followed to ensure Rosemount X-well Technology
works as specified.
In general, pipe clamp sensor installation best practices shall be followed (see
“Location and orientation” on page 3 for more details) as well as the specific
Rosemount X-well Technology requirements noted below.
Direct mounting of transmitter on pipe clamp sensor is required for
Rosemount X-well Technology to properly function. Figure 9 displays a
transmitter/pipe clamp assembly that is in a direct mount configuration.
Figure 9. Pipe Clamp Sensor Assembly in Direct Mount Configuration
Assembly shall be installed away from dynamic external temperature sources
such as a boiler or heat tracing.

Quick Start Guide
The pipe clamp sensor makes direct contact with pipe surface. Moisture
buildup between sensor and pipe surface or sensor hangup in assembly can
cause inaccurate process temperature calculations. Refer to “Install pipe
clamp sensor” on page 6 for more information on proper sensor to pipe
surface contact.
Insulation at least 1/2-in. thick (with R-value of > 0.42 m2⫻K/W) is required
over the sensor clamp assembly and sensor extension up to transmitter head
to prevent heat loss. Apply a minimum of six inches of insulation on each side
of the pipe clamp sensor. Care should be taken to minimize air gaps between
insulation and pipe. See Figure 10 for more information.
Figure 10. Pipe Clamp Insulation
Note
DO NOT apply insulation over transmitter head.
Although it will come from the factory configured as such, ensure the pipe
clamp RTD sensor is assembled in the correct wire configuration. Refer to the
appropriate transmitter reference manual for correct wire configurations.
