Absolute Pressure Transmitters

Working Principle of an Absolute Pressure Transmitter

These transmitters work on the principle of absolute zero and not relative pressure. They are not influenced by external atmospheric changes such as altitude or air pressure fluctuations. Since they have no connection with the external system, they do not need an exhaust or a release node. They convert mechanical energy or pressure into an electrical signal. So, here the pressure measured is relative to the vacuum created in the system.

Rosemount Absolute Pressure Transmitter Models

The Transmitter Shop (TTS) offers a variety of Rosemount absolute pressure transmitter models. Here are some models of Rosemount absolute pressure transmitters:

• Rosemount 3051ST Pressure Transmitters:

  These are designed for absolute and gage pressure measurements. They facilitate a direct connection between the transmitter and the processor. These transmitters are cost effective and yet offer a high level of accuracy.

• Rosemount 2088 Pressure Transmitters

  These user-friendly and high-performance pressure transmitters come with in-built configuration buttons and easy-to-use menus. They use the piezoresistive sensor technology for absolute and gage pressure measurements, and can be availed with remote seals and manifold.

• Rosemount 2051T Pressure Transmitters:

  This transmitter has a local operator interface (LOI), which reduces the number of tools required for commissioning. We ship it to you in a ready-to-be-installed state.

Common Beneficial Features of Rosemount Absolute Pressure Transmitters

Each Rosemount absolute pressure transmitter has some unique as well as common features. Here are some common beneficial features of Rosemount absolute pressure transmitters:

• Most Rosemount models are available in absolute pressure transmitter range from 0 to 10000 psi for pressure and level solutions.
• Most of the Rosemount models are designed to measure either absolute or gage pressure depending upon your application requirement.
• For most models, the user can select the output, which is either linear or square root. They offer a digital signal output based on the HART protocol.
• They have a rugged design, and the materials of construction comprise carbon steel, stainless steel, alloy C-276, or Hastelloy.
• We offer smart pressure transmitters which can be directly mounted onto the impulse line without the need for any additional brackets.
• They are equipped with smart communication systems, a leak-checked integral manifold, and external push button zero and span capabilities.
• They start up fast, and are compact and lightweight.
• They are certified for use in hazardous environments, boilers, and so on.
• They have an absolute pressure sensor with remote seals.

Applications of Rosemount Absolute Pressure Transmitters

These transmitters are used to measure the level, temperature, pressure, and flow rate of fluids and gases in closed systems, across industries. Here are some industries where absolute pressure transmitters and absolute pressure sensors are used:

• Pharmaceuticals
• Food & beverages
• Oil & gas
• Petrochemical
• Chemicals
• Science research
