1. Product Overview
The Rosemount 2088G Pressure Transmitter is a highly reliable, compact, and intelligent device engineered for precise gauge pressure (relative to atmospheric pressure) measurement. Designed for demanding industrial environments, it delivers exceptional accuracy, stability, and versatility across a wide range of applications.
Key features include:
High accuracy: Up to 0.065% of span with optional high-accuracy calibration .
Wide rangeability: A 50:1 turndown ratio ensures adaptability to diverse pressure requirements .
Robust construction: Rated for IP65/IP67 ingress protection and certified for hazardous environments (ATEX, FM, CE) .
Smart connectivity: Supports 4-20 mA HART® and 1-5 Vdc HART Low Power protocols for seamless integration with control systems.
This transmitter is ideal for applications such as process control, tank level monitoring, and pipeline pressure analysis in industries like oil and gas, chemical processing, and power generation.
2. Measurement Parameters
The 2088G is optimized for gauge pressure measurements, with a minimum range of -1.01 bar (-14.7 psi) and a maximum range of 275.8 bar (4,000 psi) . It employs a solid-state polysilicon sensor for superior linearity and minimal temperature effects. The device supports both direct-mount and remote seal configurations, enabling compatibility with high-temperature or viscous media .
Key Measurement Features:
Dynamic response: Fast settling time for rapid pressure changes.
Long-term stability: Guaranteed accuracy retention over 12 months (±0.10% URL) .
Temperature compensation: Built-in algorithms to offset thermal drift.
3. Electrical Specifications
The transmitter offers flexible power and communication options:
Power supply: 10-30 VDC (loop-powered or external supply).
Output signals:
4-20 mA HART®: Standard analog output with embedded digital communication for parameter configuration.
1-5 Vdc HART Low Power: Energy-efficient mode for battery-operated systems.
Input impedance: >500 Ω (ensures minimal signal attenuation).
Wiring configurations: 2-wire (4-20 mA) or 3-wire (1-5 Vdc) setups.
