Rosemount 1151DP4S22M1B3S2Q4 Pressure Transmitter | 4-20mA HART | China Manufacturer | Quick Lead Time

Product Overview

The Rosemount 1151DP4S22M1B3S2Q4 represents a benchmark in differential pressure measurement for demanding industrial processes. As a Smart Pressure Transmitter, it integrates a traditional 4–20 mA analog output with a digital signal based on the HART Protocol, enabling bidirectional field communication without compromising loop integrity. This model is engineered for high-accuracy applications requiring robust material compatibility, featuring a 316 SST flange, 316 SST drain and vent valves, and a 316L SST diaphragm with a silicone fill. With a calibrated measurement range of 150 inH₂O (37.3 kPa), the 1151DP4S22M1B3S2Q4 delivers precise process variable transmission for critical flow, level, and pressure monitoring in upstream, midstream, and downstream operations.

Key Features & High-End Benefits

Smart HART Communication: The integrated HART Protocol allows for remote configuration, diagnostics, and multi-variable access via a standard 4–20 mA loop. This feature significantly reduces commissioning time and enables predictive maintenance, directly supporting process optimization and minimizing unplanned downtime.

316 SST & 316L SST Wetted Materials: The use of 316 stainless steel for the flange and drain/vent assemblies, coupled with a 316L SST diaphragm, provides exceptional corrosion resistance against sour gas, chlorides, and other aggressive media. This material selection ensures long-term operational integrity in harsh environments, reducing replacement frequency and total cost of ownership.

Stable Silicone Fill Fluid: The silicone oil fill provides superior thermal stability and low hysteresis, guaranteeing repeatable performance across ambient temperature fluctuations. This stability is critical for maintaining tight control tolerances in refinery and chemical separation processes.
