Rail Mount Transmitter with Integral Mount Sensor

The least complicated assembly uses:

•an integral mount sensor with terminal block

•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 mounting accessory information.

To complete the assembly, follow the procedure described below.

1. Attach the transmitter to a suitable rail or panel.

2. Attach the thermowell to the pipe or process container wall. Install and tighten the thermowell before applying pressure.

3.Attach the sensor to the connection head and mount the entire assembly to the thermowell.

4.Attach sufficient lengths of sensor lead wire to the sensor terminal block.

5. Attach and tighten the connection head cover. Enclosure covers must be fully engaged to meet explosion-proof requirements.

6.Run sensor lead wires from the sensor assembly to the transmitter.

7.Set the transmitter failure mode switch (see Figure 2-13 on page 2-16).

8. Attach the sensor and power leads to the transmitter. Avoid contact with leads and terminals.
