Installing the Transmitter
Installing the Transmitter Output Wiring – AnalogSensor WiringBefore You Begin
2.3 Determining an appropriate location
To determine an appropriate location for the transmitter, you must consider the environmental
requirements of the transmitter and core processor, hazardous area classification, location of power
source, cable lengths, accessibility for maintenance, and visibility of the display (if the transmitter is
equipped with a display).
2.3.1 Environmental requirements
The transmitter’s environmental requirements include temperature, humidity, and vibration.
Temperature limits
Install the transmitter in an environment where ambient temperature is between –40 and +140 °F
(–40 and +60 °C). If possible, install the transmitter in a location that will prevent direct exposure to
sunlight.
Different ambient temperature requirements may apply when installing the transmitter in a hazardous
area. Refer to the approval documentation shipped with the transmitter or available on the Micro
Motion web site.
Humidity limits
Install the transmitter in an environment where relative humidity is between 5 and 95%,
non-condensing at 140 °F (60 °C).
Vibration limits
The transmitter meets IEC 68.2.6, endurance sweep, 5 to 2000 Hz, 50 sweep cycles at 1.0 g.
2.3.2 Hazardous area classifications
If you plan to mount the transmitter in a hazardous area:
• Verify that the transmitter has the appropriate hazardous area approval. Each transmitter has a
hazardous area approval tag attached to the transmitter housing.
• Ensure that any cable used between the transmitter and the sensor meets the hazardous area
requirements.
For more information about hazardous area classifications and requirements, see Section A.2.
2.3.3 Power source
Connect the transmitter to an AC or DC voltage source. The transmitter automatically recognizes the
source voltage.
AC power requirements
If you are using AC power, the following requirements apply:
• 85–265 VAC
•50/60 Hz
• 6 watts typical, 11 watts maximum
