GENERAL
CONSIDERATIONS
Measurement accuracy depends upon proper installation of the transmitter
and impulse piping. Mount the transmitter close to the process and use a
minimum of piping to achieve 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. Appendix A: Reference Data lists temperature
operating limits.
MECHANICAL
CONSIDERATIONS
NOTE
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.
Explosions can result in death or serious injury.
• Transmitters located in hazardous areas should be installed in accordance with
local codes and requirements for that area.
• Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
Electrical shock can result in death or serious injury.
• Avoid contact with the exposed leads and terminals. High voltage that may be
present on leads can cause electrical shock.
Process leaks could result in death or serious injury.
• Properly tighten process connections before applying pressure.
Apply torque only to the hex flat located at the process end of the transmitter. Do not apply
torque to the transmitter body or electrical connection - severe damage could result. Do not
exceed 100 ft-lbs.
