The installation steps for the Rosemount 644 temperature transmitter with a DIN rail-mounted sensor.
Yesterday we introduced the installation method of the Rosemount 644 temperature transmitter with threaded sensors. However, in our actual working conditions, the Rosemount 644 temperature transmitter also has a DIN rail-mounted sensor. So how is it installed? Today we will specifically introduce the installation steps for the Rosemount 644 temperature transmitter with DIN rail-mounted sensors.

Yesterday we introduced the installation method of the Rosemount 644 temperature transmitter with threaded sensor, but in our actual working conditions, the Rosemount 644 temperature transmitter also has a DIN rail-mounted sensor. So how is it installed? Today we will specifically introduce the installation steps for the Rosemount 644 temperature transmitter with a DIN rail-mounted sensor.
1. Install the thermowell onto the wall of the pipeline or process container. The thermowell should be installed and tightened before applying process pressure.
2. Check the position of the transmitter fault mode switch.
3. Assemble the transmitter onto the sensor. Push the transmitter mounting screws through the sensor mounting plate.
4. Wire from the sensor to the transmitter.
5. Insert the transmitter-sensor assembly into the junction box. Screw the transmitter mounting screws into the mounting holes of the junction box. Screw the threaded joint of the extension piece onto the housing to assemble the extension piece to the junction box. Insert the assembly into the thermowell and tighten the threaded joint.
6. If the power wiring uses a cable sealing fitting, correctly connect the cable sealing fitting to the housing conduit entry.
7. Insert the leads of the shielded cable into the junction box through the conduit entry.
8. Connect the leads of the shielded cable to the power terminals of the transmitter. Avoid contact with the sensor leads and sensor connectors. Connect and tighten the cable sealing fitting.
9. Install and tighten the junction box cover. The cover must fit tightly to meet explosion-proof requirements.
A. Junction box cover
B. Junction box
C. Thermowell
D. Rosemount 644 transmitter
E. Integrated mounting sensor with suspended leads
F. Extension piece
