Safety Messages
NOTICE
This guide provides basic guidelines for installing the Rosemount™ 148 Temperature Transmmitter. It
does not provide instructions for detailed configuration, diagnostics, maintenance, service,
troubleshooting, or installations. Refer to the Rosemount 148 Temperature Transmitter Reference
Manual for more instruction. The manual and this guide are also available electronically at
Emerson.com/Rosemount.
WARNING
Explosions
Explosions could result in death or serious injury.
Installation of device in an explosive environment must be in accordance with appropriate local,
national, and international standards, codes, and practices.
Review the Hazardous Locations Certifications for any restricions associated with a safe
installation.
WARNING
Process leaks
Process leaks could result in death or serious injury.
Install and tighten thermowells or sensors before applying pressure.
Do not remove the thermowell while in operation.
WARNING
Electrical shock
Electrical shock could cause death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can cause
electrical shock.
WARNING
Conduit/cable entries
Unless marked, the conduit/cable entries in the transmitter housing use a ½-14 NPT thread form.
Entries marked "M20" are M20 X 1.5 thread form. On devices with multiple conduit entries, all
entries have the same thread form.
Only use plugs, adapters, glands, or conduit with a compatible thread form when closing these
entries.
When installing in a hazardous location, use only appropriately listed or Ex certified plugs, glands,
or adapters in cable/conduit entries.

1 Software installation
Procedure
1. Place the Rosemount™ 148 PC Programmer CD_ROM into the drive.
2. Run setup.exe from Windows™ XP, 7, 8, or 10.
3. When first using the software, configure the appropriate COM ports
by selecting Port Settings from the Communicate menu.
4. Install MACTek® Modem drivers completely before beginning bench
configuration on the Rosemount 148 system.
Note
The software defaults to the first available COM port.

2 Configuration
2.1 Configure the transmitter
You must configure the transmitter for certain basic variables to operate.
Manufacturers pre-configure the transmitters in the factory to order
specifications or factory defaults.
You may need to configure if the transmitter has not been configured or if
the configuration variables need revision. To configure, do one of the
following:
•Order factory-configuration from Emerson Automation Solutions.
•Use the Rosemount 148 PC Programming interface in a bench
configuration setting.
The Rosemount™ 148 PC Programming Kit includes configuration software
and a communication modem.
Prerequisites
The device will need an external power supply of 12–42.4 Vdc.
Procedure
1. Hook up the transmitter and a load resistor (250–1100 ohms) wired
in series with the power supply.
2. Attach the modem in parallel with the load resistor and connect it to
the PC.
2.2 Verify configuration
If the transmitter has a sensor connected (either a test sensor or actual
installation hardware), you can check the configuration with the
Information tab on the Rosemount™ 148 PC Programmer Interface.
Procedure
1. Select Refresh to update the status and confirm that the transmitter
has been configured correctly.
2. If there are any problems, refer to the Rosemount 148 Temperature
Transmitter Reference Manual for troubleshooting suggestions.

Procedure
1. Attach the thermowell to the pipe or process container wall.
2. Install and tighten thermowells before applying process pressure.
3. Assemble the transmitter to the sensor.
a) Push the transmitter mounting screws through the sensor
mounting plate.
b) Insert the snap rings (optional) into the transmitter mounting
screw groove.
4. Wire the sensor to the transmitter.
5. Insert the transmitter-sensor assembly into the connection head.
a) Thread the transmitter mounting screw into the connection
head mounting holes.
b) Assemble the extension to the connection head.
c) Insert the assembly into the thermowell.
6. Slip the shielded cable though the cable gland.
7. Attach a cable gland into the shielded cable.
8. Insert the shielded cable leads into the connection head through the
cable entry.
9. Connect and tighten the cable gland.
10. Connect the shielded power cable leads to the transmitter power
terminals.
Avoid contact with sensor leads and sensor connections.
11. Install and tighten the connection head cover.
