be installed in any position around the circumference of the pipe
for partial pipe flow applications.

Horizontal Orientation

For full pipe flow applications, mount the pipe clamp sensor on the upper half of the pipe. Refer to Figure 3-1 in the Quick Start Guide for the recommended zone.

Vertical Orientation

The pipe clamp sensor can be installed in any position around the circumference of the pipe. Refer to Figure 3-2 in the Quick Start Guide for more information.

Special Considerations

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. Refer to Figure 3-3 in the Quick Start Guide for more information.
Wireless transmitters with external antennas allow for multiple antenna configurations. All wireless transmitters 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.

Safety messages

WARNING

Physical access

Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end users’ equipment. This could be intentional or unintentional and needs to be protected against.
Physical security is an important part of any security program and fundamental to protecting your system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for all systems used within the facility.

CAUTION

Conduit/cable entries

Unless otherwise marked, the conduit/cable entries in the housing enclosure use a ½- NPT form. Only use plugs, adapters, glands, or conduit with a compatible thread form when closing these entries.
Entries marked M20 are M20 x 1.5 thread form. On devices with multiple conduit entries, all entries will have the same thread form.
When installing in a hazardous location, use only appropriately listed or Ex certified plugs, glands, or adapters in cable/conduit entries.

CAUTION

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 a torque of 2 lbf · in 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 the Rosemount 0085 Pipe Clamp Sensor Assembly exploded view for the location of each part.

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.

Vertical orientation

The pipe clamp sensor can be installed in any position around the circumference of the pipe.

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.
Wireless transmitters with external antennas allow for multiple antenna configurations. All wireless transmitters 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.

Install pipe clamp sensor

Select the area for pipe clamp sensor installation with the recommendations outlined in Horizontal orientation. Mount the pipe clamp sensor on the pipe and 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 3-3 for more information. Tighten the bolts to secure the pipe clamp sensor to the pipe.

Procedure for replacing the spring-loaded sensor in the pipe clamp sensor.
The spring-loaded sensor can be ordered for replacement using the Rosemount 0085 Pipe Clamp Sensor Product Data Sheet.

Procedure

Loosen and remove the original sensor from the extension of the pipe clamp.
Add pipe compound or PTFE tape (where local piping codes allow) to the threads of the new sensor.
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 the Replacement sensor for more information.
Screw in the sensor and tighten to 24 ft-lbs of torque.

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 an incorrect sensor will result in inaccurate process temperature calculations. It is extremely important the above requirements and installation steps 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 ) as well as the specific Rosemount X-well Technology requirements noted below:
Direct mounting of the transmitter on a pipe clamp sensor is required for Rosemount X-well Technology to properly function. Figure 6-1 displays a transmitter/pipe clamp assembly that is in a direct mount configuration.
Assembly shall be installed away from dynamic external temperature sources such as a boiler or heat tracing.
The pipe clamp sensor makes direct contact with the pipe surface. Moisture buildup between the sensor and the pipe surface or the sensor hangup in the assembly can cause inaccurate process temperature calculations. Refer to Install pipe clamp sensor for more information on proper sensor to pipe surface contact.
Insulation at least ½-in. thick (with R-value of > 0.42 m2 × K/W) is required over the sensor clamp assembly and the sensor extension up to the 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 6-2 for more information.

Note

DO NOT apply insulation over the transmitter head.
Although it will come from the factory configured as such, ensure that the pipe clamp RTD sensor is assembled in the correct wire configuration. Refer to the appropriate transmitter reference manual for correct wire configurations.
