<h2>Overview</h2>
<p>The <strong>Rosemount 01151-0935-0001 Model 1151 Smart Retrofit Kit</strong> is a field-retrofit solution that upgrades analog 1151 pressure transmitters to full HART protocol capability. Rather than replacing the entire transmitter, this kit retrofits the electronics module, preserving investment in existing sensor heads while adding diagnostic and communication features of modern smart instrumentation. Ideal for brownfield upgrades in refineries, chemical plants, and process facilities.</p>
<h2>Key Features</h2>
<ul>
<li>Converts analog 1151 transmitters to HART-enabled smart output</li>
<li>Drop-in electronics retrofit—no piping or mounting changes required</li>
<li>Compatible with Rosemount 1151DP, 1151HP, 1151GP, and 1151AP models</li>
<li>Maintains calibration and pressure ranges of the original transmitter</li>
<li>Includes Smart Transmitter Electronics module and necessary board spacer and terminal eyelet kits</li>
<li>Factory sealed, new in box condition</li>
</ul>
