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