Improve Control & Reduce Maintenance
Stand-alone mechanical pressure switches used in chemical pump control are prone to drift, hysteresis, slow response and contact degradation, leading to inconsistent trip points and reduced interlock reliability. These issues are exacerbated in corrosive and thermally variable environments, where frequent recalibration is often required.
The Rosemount 4051S Pressure Transmitter addresses these limitations by deriving switch actions from a stable, high-accuracy pressure measurement rather than a mechanical mechanism. Its SuperModule architecture delivers exceptional long-term stability with minimal drift, while integrated solid-state relay outputs ensure precise and repeatable actuation points. By combining measurement and switching within a single robust device, the Rosemount 4051S Pressure Transmitter enhances control reliability, reduces maintenance requirements and improves overall pump protection in demanding chemical process applications.
