A Legacy of Precision, Unwavering Reliability: The Rosemount 3051CD Differential Pressure Transmitter (HART Protocol / Explosion-Proof)

In the process industry, the Rosemount 3051 series has long been a symbol of unparalleled reliability, accuracy, and technological heritage in the field of pressure measurement. Nowadays, Xi'an Xinyi Instrument Technology Co., Ltd. brings this classic original Rosemount 3051CD differential pressure transmitter (HART protocol/explosion-proof type) to domestic users. It embodies decades of on-site experience and technological essence, providing a globally validated "gold standard" solution for key flow, liquid level, density, and pressure measurements in industries such as petroleum, chemical, power, and metallurgy with its exceptional stability, rich self diagnostic capabilities, and powerful HART communication capabilities.

1. Globally Recognized Classic Platform andPerformance

The 3051CD inherits theperformance genes of the Rosemount family. Its sensor is ingeniously designed to measure both differential pressure and static pressure simultaneously, transmitted remotely via HART communication protocol. The device features extremely fast response (power-up time < 15 seconds), excellent static pressure effect (±(0.05% URL + 0.075% Span)/10MPa), and minimal power supply effect (±0.001%/10V), ensuring it consistently delivers and reliable process variables amidst complex process fluctuations.

2. Powerful Intelligence and Self-Diagnostic Capabilities

This is more than just a transmitter; it's an intelligent field instrument node. Using the HART protocol, engineers can remotely configure, commission, and monitor it from the control room or with a handheld communicator. Its built-in self-diagnostic functions continuously monitor the transmitter's health and can provide status outputs for pressure high/low alarms, significantly enhancing the plant's predictive maintenance capabilities and overall safety.

3. Rugged and Durable Explosion-Proof Design, Wide Applicability

The product features a 316L stainless steel housing with an IP65 protection rating, capable of withstanding moisture, dust, and corrosion in industrial environments. It is meticulously engineered to operate in ambient temperatures ranging from -20°C to 80°C and withstand working pressures up to 40 MPa. With standard process connections like 1/4-18 NPT or 7/16-20 UNF threads, it can be easily integrated into various existing piping systems.

Key Technical Parameters and Industrial Applications

Solid Parameters, Forging a Classic:

  • Model: Rosemount 3051CD Differential Pressure Transmitter (HART Protocol / Explosion-Proof).

  • Measurement Types: Suitable for flow, level, density, and pressure measurement of liquids, gases, and steam.

  • Pressure Range: Covers -0.1~0...0.01~100 MPa.

  • Accuracy Class: ±0.5% FS (standard), meeting the vast majority of industrial measurement needs.

  • Output Signal: Standard two-wire 4-20mA with superimposed HART protocol, optional 0-10/20mA, 0/1-5VDC.

  • Power Supply: 15～30 VDC.

  • Static Pressure Effect: ±(0.05% URL + 0.075% Span)/10MPa.

  • Environmental Endurance: Operating temperature -20°C ~ 80°C; Protection rating IP65.

  • Process Connection: Flange with fixing thread, 1/4-18 NPT and 7/16-20 UNF female threads on both sides.

  • Sensor Material: 316L stainless steel.

Widely Applied in Core Industrial Processes:

  • Oil & Gas: Flow metering in oil/gas pipelines (used with orifice plates, nozzles, etc.), separator level control, filter differential pressure monitoring.

  • Chemical & Fine Chemical: Reactor level, distillation column bottom level, tray pressure drop, clogging monitoring of pump outlet filters.

  • Power & Energy: Boiler drum level (three-element control), feedwater flow, primary/secondary air pressure, differential pressure monitoring in flue gas desulfurization systems.

  • Metallurgy & Papermaking: Blast furnace gas pressure, pulp level, steam flow measurement.
