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.

August 2017

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.
