2051CD2A02A1BH2B1I1D4V5 Rosemount Pressure Temperature Transmitter 24 V DC

2051CD2A02A1BH2B1I1D4V5 Description

2051CD2A02A1BH2B1I1D4V5 Features

• Ceramic Capacitive Sensor:​ Utilizes a durable, monolithic Al2O3 (alumina) ceramic diaphragm and capacitor cell, offering exceptional resistance to corrosion, abrasion, and hydrogen permeation. The smooth, non-stick surface minimizes material build-up.
• Long-term Stability & Reliability:​ The ceramic sensor is virtually immune to process-induced stress, delivering excellent long-term zero and span stability, which reduces maintenance and recalibration frequency.
• Exceptional Overpressure Protection:​ Designed to withstand high static line pressures and overpressure conditions without damage to the sensor, enhancing operational safety and transmitter life.
• Advanced Diagnostics:​ Integrated diagnostics via HART 7 protocol allow for monitoring of transmitter health, detection of process anomalies (like plugged impulse lines), and predictive maintenance.
• Robust Construction:​ Features a rugged, NEMA 4X (IP66) aluminum or stainless steel housing. The remote seal system (as configured in this model) isolates the transmitter from extreme temperatures or harsh process fluids.
• Flexible Configuration:​ The extensive model code allows for precise selection of process connections, flanges, diaphragm materials, fill fluid, and electrical options to match the exact application requirements.
• Global Approvals:​ Certified for use in hazardous areas (ATEX, IECEx, etc.) and general purpose locations worldwide.

2051CD2A02A1BH2B1I1D4V5 Materials, Construction & Applications

• Materials:​ The primary sensor is 99.9% pure alumina ceramic. Wetted parts (remote seals) in this configuration are typically 316L stainless steel with a FEP (or other specified) diaphragm lining. The fill fluid is a stable, temperature-compensated silicone or Halocarbon oil. The housing is aluminum with a polyurethane coating or optional stainless steel.
• Construction:​ A two-compartment design separates the electronics module from the sensor/connection module. The remote seal system (flanged or threaded) connects via capillary tubes filled with a stable fluid to transfer the process pressure to the isolated ceramic sensor. The design is modular for easy service.
• Primary Applications:
  • Chemical Processing:​ Corrosive liquid and gas flow, level, and pressure measurement in reactors, columns, and pipelines.
  • Oil & Gas:​ Abrasive and viscous service such as drilling mud, heavy crude, slurry flow, and separator level measurement.
  • Power Generation:​ Flue gas draft pressure, scrubber differential pressure, and ash slurry applications.
  • Pulp & Paper:​ Stock chest level, black liquor, and other abrasive/corrosive slurry measurements.
  • Water & Wastewater:​ Sludge, slurry, and chemical level/flow measurement.
