Internal antenna position

The internal antenna is designed for multiple mounting orientations. The transmitter should be mounted according to measurement best practices for your pressure measurement application. The antenna should be approximately 3 ft (1 m) from any large structure or building to allow clear communication to other devices.

Field communicator connections

In order for the Field Communicator to interface with the Rosemount 2051 Wireless Transmitter, the Power Module must be connected. Refer to Figure 3-1for a diagram on how to connect the Field Communicator.

3.3.3Mechanical considerations

Steam service

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. Refer to Figure 3-11 on page 43 for correct mounting orientation.

Side mounted

When the transmitter is mounted on its side, position the Coplanar flange to ensure proper venting or draining. Mount the flange as shown in Figure 3-11 on page 43, keeping drain/vent connections on the bottom for gas service and on the top for liquid service.

3.3.4Environmental 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: Specifications and Reference Data that 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.
