GENERAL
CONSIDERATIONS
Measurement accuracy depends on proper installation of the transmitter and
impulse piping. Mount the transmitter close to the process and use a
minimum of impulse piping to achieve the best accuracy. Also, consider the
need for easy access, personnel safety, practical field calibration, and a
suitable transmitter environment. Install the transmitter to minimize vibration,
shock, and temperature fluctuation.
IMPORTANT
Install the enclosed pipe plug (found in the box) in unused conduit opening
with a minimum of five threads engaged to comply with explosion-proof
requirements.
For material compatibility considerations, see document number
00816-0100-3045 on www.emersonprocess.com/rosemount.
MECHANICAL
CONSIDERATIONS
NOTE
For steam service or for applications with process temperatures greater than
the limits of the transmitter, do not blow down impulse piping through the
transmitter. Flush lines with the blocking valves closed and refill lines with
water before resuming measurement.
ENVIRONMENTAL
CONSIDERATIONS
Best practice is to mount the transmitter in an environment that has minimal
ambient temperature change. The transmitter electronics temperature
operating limits are -40 to 185 °F (-40 to 85 °C). Refer to Appendix A:
Reference Data which lists the sensing element operating limits. Mount the
transmitter so that it is not susceptible to vibration and mechanical shock and
does not have external contact with corrosive materials.
