Flush Diaphragm Pressure Transmitters

Flush diaphragm pressure transmitters offer a specialized solution for pressure measurement in challenging applications involving viscous media, substances requiring hygienic compatibility, or environments prone to clogging. Their exposed diaphragm design prevents media buildup, ensuring accurate readings and minimizing maintenance.

Find out more about Flush Diaphragm Pressure Transmitters to determine which product options and capabilities will best meet your application requirements.

Flush diaphragm pressure transmitters are uniquely designed to tackle the challenges posed by viscous fluids and stringent sanitary requirements. Unlike traditional pressure transmitters with recessed diaphragms, these devices feature an exposed diaphragm that sits flush with the process connection. This eliminates internal cavities where viscous media could accumulate and clog, leading to inaccurate readings or even sensor failure.

The direct contact between the diaphragm and the process fluid also allows for superior hygienic compatibility. There are no hidden crevices or dead spaces where contaminants can harbor, making these transmitters ideal for industries such as food and beverage, pharmaceuticals, and biotechnology, where cleanliness is paramount.

Key Advantages of Flush Diaphragm Pressure Transmitters

  • Uninterrupted Measurement of Viscous Media: Ideal for applications involving thick fluids like plastics, paper pulp, bitumen, sewage, paint, and adhesives.
  • Enhanced Hygienic Compatibility: The absence of internal cavities minimizes the risk of contamination, ensuring product integrity and regulatory compliance.
  • Reduced Maintenance: The self-cleaning nature of the flush diaphragm minimizes the need for frequent cleaning and maintenance, improving operational efficiency.
  • Versatile Installation Options: Available with various process connections like screw-in, tri-clamp, dairy, and flange mounts to accommodate diverse installations.
  • Wide Application Range: Suitable for various industries, including food and beverage, pharmaceuticals, biotechnology, wastewater treatment, and chemical processing.

Choosing the Right Flush Diaphragm Pressure Transmitter

Selecting the optimal transmitter involves considering factors such as:

  • Media Compatibility: Ensure the diaphragm and wetted materials are compatible with the process fluid to prevent corrosion and ensure longevity.
  • Pressure Range: Choose a transmitter with a suitable pressure range to accurately measure the expected process pressures.
  • Process Connection: Select the appropriate connection type to match your existing piping and equipment.
  • Output Signal: Most flush diaphragm transmitters offer a 4-20mA current loop output for easy integration with control systems.
  • Environmental Considerations: Consider the operating temperature, humidity, and potential exposure to harsh chemicals when choosing a transmitter.

Applications of Flush Diaphragm Pressure Transmitters

  • Food and Beverage Processing: Monitoring pressure in pipelines, tanks, and vessels containing viscous products like sauces, syrups, and pastes.
  • Pharmaceutical Manufacturing: Ensuring accurate pressure control in sterile processes involving liquids, gels, and creams.
  • Biotechnology: Measuring pressure in bioreactors and fermenters handling cell cultures and other sensitive biological materials.
  • Wastewater Treatment: Monitoring pressure in pumps and pipelines transporting sludge and other viscous waste products.
  • Chemical Processing: Measuring pressure in reactors and vessels containing corrosive or reactive chemicals.

Flush diaphragm pressure transmitters offer a reliable and hygienic solution for pressure measurement in demanding applications. Their unique design and construction overcome the challenges posed by viscous media and stringent sanitary requirements, ensuring accurate and uninterrupted process control.
