Head Mount Transmitter with DIN Plate Style Sensor
The least complicated assembly uses:
• an integral mount sensor with flying leads
• an integral DIN style connection head
• a standard extension
• a threaded thermowell
Refer to Volume 2 of the Rosemount Sensors Product Data Sheet
(document number 00813-0101-2654) for complete sensor and

3. Assemble the transmitter to the sensor. Push the transmitter
mounting screws through the sensor mounting plate and insert the
snap rings (optional, part number 00644-4432-0001) into the
groove of each transmitter mounting screw.
4. Insert the transmitter-sensor assembly into the connection head.
Thread the transmitter mounting screw into the connection head
mounting holes.
