Fuji Electric FKC Differential Pressure Transmitter: Dependable Pressure Measurement for Industrial Applications

Accurate pressure measurement is essential for safe, efficient and reliable industrial process. From chemical manufacturing and hydrogen production to fluid flow and liquid-level monitoring, industries need pressure instruments that provide consistent measurements even in difficult operating conditions.

The Fuji Electric FKC Differential Pressure Transmitter is suitable for industrial applications where accurate and stable long term measurement of differential pressure, flow and related process parameters are required. Fuji Electric pressure transmitters are equipped with state-of-the-art sensor technology and come in a variety of versions suitable for the harsh conditions of the industrial environment.

Fuji Electric has accumulated a wealth of experience in industrial pressure measurement technology, having supplied over 1,000,000 FCX Series electronic transmitters worldwide. The FCX-AIII series incorporates a micro-capacitance silicon sensor built with micro-machining technology for precise measurement of pressure, differential pressure, fluid flow, and liquid levels.

What is Fuji Electric FKC Differential Pressure Transmitter?

Differential Pressure Transmitters These measure the difference between the pressure at two points in a process system. This measurement can be used for flow, liquid level, filtration conditions and other important process parameters.

The Fuji Electric FKC Differential Pressure Transmitter is part of Fuji Electric’s pressure measurement solutions and is designed for applications requiring stable and accurate differential pressure measurement.

A differential pressure transmitter is unlike a simple pressure gage that can convert the pressure difference it measures to an electrical signal to be integrated with industrial control and automation systems.

Differential pressure transmitters are therefore very useful in:

• Automation of processes
• Flow measurement
• Measurement of liquid level
• Chemical processing
• Hydrogen Generation
• Filtration units
• Manufacturing (Industry)

High-end sensor technology for precise measurement

Fuji Electric pressure transmitters feature micro-capacitance silicon sensors as one of their important technologies.

Fuji Electric developed this sensor with micro-machining technology for high precision measurements. The sensor is a major part of the FCX-AIII series, and it enables the measurement of pressure, differential pressure, fluid flow and liquid levels.

The use of advanced sensor technology enables stable measurement during long operating periods. This is especially important for industrial facilities where instruments can be continuously in operation for many years.

FCX Series has demonstrated its value in industrial measurement applications with more than 1,000,000 units delivered worldwide.

Stability of Long-Term Measurement

In industry pressure measuring equipment is often required to run for years without interruption. High replacement frequency or unstable measurements raise maintenance requirements and affect process efficiency.

With more than 10 years of long-term stability, Fuji Electric pressure transmitters enable industries to realize reliable pressure monitoring for years to come.

This type of long term stability can be particularly useful in applications where:

• It is necessary to operate continuously
• Difficult to access for maintenance
• Process shutdowns cost money
• Measurement accuracy is important
• Equipment operating in difficult conditions

When choosing the right transmitter for industrial users, long-term measurement stability is often a critical consideration especially when opting for a Fuji Electric FKC Differential Pressure Transmitter.

Corrosion resistant diaphragm materials

Industrial processes often work with aggressive chemicals, corrosive gasses, acids, alkalis and other harsh materials. Thus, the correct diaphragm material is indispensable for the reliability of the transmitter.

For individual process conditions Fuji Electric provides a variety of diaphragm materials.

Gold & Ceramics

Gold and ceramic anti-corrosive diaphragm solutions for applications including:

• Desulphurization plants
• Production of Hydrogen
• Hydrogen delivery systems

For special Hydroseal type transmitters, the seal diaphragm is made of 316L stainless steel with a double coating of gold and ceramics. This configuration is suitable for measuring liquids and gasses including applications with high concentrations of hydrogen.

Zirconium

Zirconium diaphragms may be chosen for demanding chemical applications involving substances like:

• Muriatic Acid
• C. Sodium Hydroxide
• Bleaching agents

Titanium

Titanium diaphragms are also available for use with sulfur compounds and chlorides.

Hastelloy C

Hastelloy-C is offered as an alternative for applications involving:

• Acids (organic)
• Inorganic acids

Monel

Monel diaphragm choices for alkalis and fluorine service are available.

Tantalum

Tantalum is suitable for particularly aggressive chemical environments involving:

• Hydrochloric acid HCl
• Sulfuric acid
• Aqua regia
• Nitric acid

The availability of these different materials allows the user to select a transmitter configuration for the characteristics of the process fluid and the operating environment.

Fuji Electric FKC Differential Pressure Transmitter Usage

The versatility of differential pressure measurement means Fuji Electric transmitters are used in a wide range of industrial applications.

Flow Measurements

Differential pressure is a common method of measuring fluid flow in industrial piping systems.

The flow rate is determined by the pressure differential across an appropriate flow element, as measured by the process control system. Therefore, industrial flow measurement applications can include an appropriate Fuji Electric FKC Differential Pressure Transmitter.

Liquid-Level Measurement

Differential pressure measurement can also be used for the monitoring of liquid levels in tanks and vessels.

The pressure of the column of liquid varies with the height and the density. The transmitter is able to measure the pressure difference which gives useful information about the level inside the vessel.

Chemical Processing

Chemical plants often work with corrosive materials and difficult process conditions. Fuji Electric transmitters can be set up for different chemical environments due to the availability of specialized diaphragm materials such as Hastelloy-C, Monel, Tantalum, Zirconium and Titanium.

Uses of Hydrogen

The nature of hydrogen and the operating conditions may require specialized measurement equipment in the production and supply systems of hydrogen.

Fuji Electric has Hydroseal-type transmitter configurations for liquid and gas measurement including high concentration hydrogen applications with gold and ceramic coatings on the 316L stainless-steel seal diaphragm.

Desulfurisation

Desulphurization plants often subject measuring instruments to corrosive process conditions. For applications requiring added corrosion resistance there are options for a gold and ceramic diaphragm.

High-Temperature and High-Vacuum Uses

Some industrial processes operate at high temperatures or in high vacuum, where existing measurement setups may be inadequate.

Fuji Electric’s remote-seal type transmitter is designed for stable measurement under high temperature and high vacuum. A special treatment method is used to support measurement stability in these challenging environments.

Fast Response and Simple Field Setup

The response time of the transmitter is important because industrial processes can change rapidly.

Fuji Electric pressure transmitters have a fast response time of less than 60 milliseconds, so measurement systems can respond quickly to changes in process conditions.

A further useful feature is the ability to configure the transmitter in the field with push buttons. This can help with adjustment and configuration during installation, commissioning or maintenance.

Field configuration can reduce dependence on other programming equipment and facilitate technicians’ ability to make necessary adjustments at the installation site.

Versatility of Installation

Industrial plants may have complex piping arrangements and limited space for installation. Fuji Electric pressure transmitters are designed for installation flexibility and can be mounted on a variety of pipe layouts.

There are a lot of transmitter configurations to choose from so users can choose a model that meets their process requirements and installation conditions.

For applications where the transmitter cannot be mounted directly at the process point, for example in case of temperature or vacuum, the remote-seal configuration offers an alternative solution.
