Traditional Flange (H2)

Option PM is a SST pipe mount bracket assembly designed for use in pipe mounting the Traditional Flange (H2). It is the same bracket used on other RNII nuclear qualified transmitters, including the Rosemount 1154 Series H.

When installing the transmitter to the optional mounting brackets, torque the bolts to 21 foot-pounds. See “Mounting” in Section 3 for additional mounting considerations.

The traditional flange option converts the mounting configuration of the Rosemount 3051N to one similar to traditional style transmitters. This allows the Rosemount 3051N to replace traditional transmitters without changing existing manifolds, impulse piping, or bracket arrangements. The traditional flange also allows a higher process temperature at the process ports (300 °F [149 °C]) because of its ability to dissipate heat.

The traditional flange fits most existing mounting brackets. If a new bracket is required, use one of the bracket options described earlier. Figure 6-3 in Section 6 shows the traditional flange.

TRANSIENT PROTECTION TERMINAL BLOCK (T1)

The standard transient protection terminal block increases the Rosemount 3051N Pressure Transmitter’s ability to withstand electrical transients. Rosemount 3051N Pressure Transmitters, with integral transient protection installed, meet the standard performance specifications as outlined in this product manual.

NOTE

Installation of the transient protection terminal block does not provide transient protection unless the Rosemount 3051N transmitter case is properly grounded. See Section 3 for grounding information.
