It offers proven reliability and accurate, stable, and reliable pressure measurement across a wide range of industrial applications.

The Rosemount 2088 Smart Pressure Transmitter uses piezoresistive sensor technology, converting applied pressure into precise electrical signals through the piezoresistive effect. Its solid-state polysilicon pressure sensor works with a 316L stainless steel isolating diaphragm. This design ensures long-term stability, high accuracy, and resistance to tough process conditions.

This Pressure Transmitter (0 to 3 BAR) comes in gauge and absolute types. It works well in oil and gas, chemical, HVAC, and water treatment applications. They design it for municipal water and wastewater operators.

It offers a lightweight and compact design. This makes installation and maintenance easier while keeping measurement accuracy.

Inside, the Rosemount 2088 features a Wheatstone bridge circuit and precision strain gauges to ensure dependable signal conversion. Its smart electronics and built-in configuration buttons make calibration and setup straightforward—no external tools required.

2. What is the difference between Rosemount 2088 and 3051?

The Rosemount 2088 is a compact, cost-effective gauge and absolute pressure transmitter ideal for standard industrial use. It offers good accuracy (about ±0.075% of span) and reliable diagnostics. Its easy setup makes it great for general use.

In contrast, the Rosemount 3051 series offers higher accuracy (about ±0.04%), advanced diagnostics, and a broader measurement range. The 3051 suits critical process control applications that require extreme precision and extended functionality.

If you need a simple, reliable, and durable transmitter, the Rosemount 2088 is an excellent choice. Experts recommend the Rosemount 3051 for high-end precision and advanced communication.

3. How accurate is the Rosemount 2088 Pressure Transmitter?

The Rosemount 2088 Pressure Transmitter provides standard accuracy of ±0.10% of span, ensuring precise, repeatable results in industrial settings.

For applications requiring tighter control, a high-accuracy version is available with performance up to ±0.065% of span. This level of precision keeps readings stable and reduces drift. This makes the Rosemount 2088 Gauge Pressure Transmitter good for routine tasks and important process monitoring.

4. Are Emerson and Rosemount the same?

Emerson is a global industrial technology leader that designs automation, control, and instrumentation products.

Rosemount, a brand under Emerson, specializes in pressure, temperature, flow, and level measurement solutions.

The Emerson Rosemount 2088 represents the brand’s commitment to delivering innovative, dependable, and precise instrumentation. While Emerson is the parent company, Rosemount focuses on high-performance sensing and control equipment widely used across industries.
