The Rosemount 2088 is a highly customizable and robust pressure transmitter used in various industrial automation applications. With the wide variety of sensor materials, process connections, and configurations available, selecting the right 2088 setup requires understanding your specific pressure measurement needs.

Key Factors to Consider for Configuration

Determining the optimal Rosemount 2088 configuration involves assessing several aspects of your process:

Pressure Range

Consider the minimum, maximum, and normal operating pressures. This determines the span and helps select the right sensor technology.

Process Media Compatibility

Knowing the media type like gas, liquid or steam determines the required sensor diaphragm material compatibility.

Process Temperature

The high and low process temperatures impact the sensor technology selection to find one able to withstand those extremes.

Required Accuracy and Response Time

The needed accuracy and response speed, such as for process control, guide the selection of sensor technology and transmitters.

Selecting the Optimal Pressure Sensor Technology

The Rosemount 2088 offers multiple sensor technologies like capacitance cells and piezoresistive sensors to suit different pressure ranges and process conditions:

Capacitance Cells for Absolute, Gauge, and Differential Pressures

Capacitance cell sensors provide high accuracy and fast response across wide pressure ranges up to 5000 psi, in gas, liquid, or steam applications.

Piezoresistive for Higher Pressures and Temperatures

Silicon piezoresistive sensors offer excellent performance for absolute, gauge, or differential pressures up to 20,000 psi, at high temperatures up to 850°F.

Thin Film for Cryogenic and High Static Pressures

Thin film sensors measure absolute and differential pressures from cryogenic levels to 15,000 psi. With near-zero temperature effects, they are ideal for ballistics testing applications.

Choosing Compatible Process Wetted Parts

The transmitter body, flanges, and sensor diaphragm materials must be compatible with the process media to prevent corrosion:

Corrosion-Resistant Metals

Stainless steel construction with Hastelloy or other corrosion-resistant metal diaphragms provides long service life in most chemical process environments.

Specialty Alloys and Ceramics

For very corrosive amine or acid services, specialized nickel alloys or ceramics like Alumina and Ziconia ensure optimal sensor protection and life.

Selecting Process Connections

Various process connection options are available to suit different installation requirements:

Flanged Connections

Flanged connections allow easy transmitter mounting and removal during maintenance. Options like raised face, ring joint, and lap joint flanges are available.

Threaded Connections

Threaded transmitter body connections provide lower-cost installation. However, transmitters are not as easily removable compared to flanged designs.

Sanitary Fittings

For hygienic processes like food and pharmaceutical, sanitary clamp or tri-clamp connections enable cleanroom specification compliance.

Choosing Additional Options

Additional configurations like remote seals for high temperatures, manifolds for multiple pressure lines, and wireless adapters add expanded capabilities:

Remote Seals for High or Low-Temperature Services

Remote seals facilitate transmitter body placement away from hot or cryogenic processes while the sensor withstands the temperatures.

Manifolds for Efficient Multi-line Measurement

Manifolds allow connecting several process lines to one transmitter, saving costs and space while simplifying wiring.

Wireless Transmitters for Hard-to-Reach Applications

Wireless adapters enable battery-powered operation without cabling for difficult locations while providing digital communication abilities.

By thoroughly evaluating your pressure application requirements, you can leverage the Rosemount 2088’s modular options to arrive at the optimal configuration matching your needs. The wide flexibility helps meet the challenges of diverse industrial pressure measurement applications.
