Product Overview

The ROSEMOUNT 2051CD2A02A1AS3I1M5 405PS100N065D3H is a highly reliable field instrument utilized to calculate differential pressure by utilizing an advanced capacitance sensor mechanism. It features a signature Coplanar platform design, which simplifies process connections by allowing direct integration with manifold blocks, primary flow meters, or remote diaphragm seals without complex external tubing. It is engineered with premium 316L stainless steel process isolating diaphragms, a lightweight polyurethane-coated aluminum housing, and a built-in LCD indicator panel. Operating over a traditional two-wire configuration, it translates physical pressure changes into a standardized 4–20 mA current loop superimposed with digital HART communication, providing process plants with exceptional performance stability and granular configuration diagnostics.

u Output Current: Two-wire 4–20 mA DC loop configuration

u Supply Voltage: Operates on 10.5 to 42.4 VDC at terminal connections

u Operating Temperature Limits: Ambient operating range spanning -40 °C to 85 °C

u Process Sensor Temperature Limits: Internal silicone fill fluid sensor limits spanning -40 °C to 121 °C

u Reference Accuracy: Standard calibration accuracy rating up to ±0.065% of the configured span

u Maximum Working Pressure (URL): Up to 2,000 psi (137.9 bar) differential limit capability

Product Applications

² Flow Measurement: Paired with compact orifices or Annubar primary flow devices to calculate fluid velocity through closed industrial pipes via square-root calculations.

² Liquid Level Monitoring: Installed at the base of closed chemical containers to compute precise hydrostatic liquid levels based on differential tank head readings.

² Filter Monitoring: Measuring upstream and downstream pressure differentials across large-scale industrial water filters to proactively determine maintenance or backwash intervals.
