Key

Features

Flush Diaphragm Process Connection

The Hogller HOF series pressure transmitter stands out for its flush diaphragm process connection, a key feature that offers several advantages, particularly for applications involving challenging media:

  • Suitable for Slurry and Particle-Laden Media: Unlike traditional pressure transmitters with recessed diaphragms, the HOF series’ flush design minimizes crevices where particles can accumulate. This makes it ideal for harsh environments with abrasive or viscous media, such as slurries, heavy oils, or liquids with suspended solids.

  • Improved Cleanability: The smooth, flush diaphragm surface simplifies cleaning and sanitation procedures. This reduces the risk of contamination buildup and ensures accurate pressure measurement over time, especially critical in hygienic or sanitary process applications.
  • Reduced Clogging: The absence of cavities in the flush diaphragm design prevents particles from becoming lodged and obstructing the pressure reading. This enhances the transmitter’s reliability and reduces the need for maintenance in environments with dirty or debris-laden media.

In addition to these benefits, the flush diaphragm design may also contribute to a more compact overall transmitter profile, potentially simplifying installation in space-constrained applications.

The Hogller HOF series boasts impressive accuracy with an overall rating of ≤ ±0.35% of Full Scale Range (FS) [Best Fitted Straight Line (BFSL)]. This indicates that the transmitter’s output reading will closely match the true pressure value across its measurement range. However, for a more complete understanding of the transmitter’s accuracy, it’s important to consider additional specifications:

  • Non-linearity, hysteresis, non-repeatability: These terms represent slight deviations from perfect linearity in the pressure-output response. They are typically very small in high-quality transmitters like the HOF series and are often specified in a datasheet as a percentage of FS.

  • Zero offset and final offset: These terms refer to potential shifts in the output signal at zero pressure and full scale, respectively. They are usually expressed as a percentage of FS or voltage units.

While the overall accuracy specification provides a good general idea of the transmitter’s performance, consulting the datasheet for these detailed specifications will ensure it meets the specific requirements of your application.

The Hogller HOF series pressure transmitter is built to withstand demanding industrial environments. Here’s a breakdown of its key construction elements:

  • Rugged Stainless Steel Body: The transmitter housing is constructed from high-quality stainless steel 304 (SS304), offering excellent corrosion resistance and durability. For applications requiring enhanced resistance to aggressive chemicals or high temperatures, an optional stainless steel 316L (SS316L) version is available.

  • Wetted Parts Material: The components that come into direct contact with the measured media (wetted parts) are manufactured from SS304 or SS316L (optional), ensuring compatibility with a wide range of fluids. Additionally, an FKM seal material provides a reliable barrier against leaks.

  • Process Connection: The type of process connection on the HOF transmitter depends on the chosen pressure range:

    • Pressure Range ≤ 60 bar: G 1/2″ A, Male thread for easy installation.
    • Pressure Range > 60 bar: G 1″ A, Male thread for applications requiring higher pressure handling.

This combination of robust materials and well-designed process connections ensures the HOF series pressure transmitter delivers long-lasting performance in even the most challenging industrial settings.

The Hogller HOF series pressure transmitter boasts an impressive response time of less than 1 millisecond (ms). This rapid response makes it ideal for capturing fast-changing pressure fluctuations in dynamic processes.

Here’s why a fast response time is crucial in certain industries:

  • Accurate Measurement of Rapid Events: In applications where pressure changes occur quickly, such as flow control systems, hydraulic presses, or engine monitoring, a slow response time can lead to inaccurate readings. The HOF series’ fast response ensures that even transient pressure spikes or dips are captured and reflected in the output signal.

  • Improved Process Control: By providing real-time pressure data, the HOF series allows for tighter control over dynamic processes. This can optimize performance, enhance efficiency, and minimize potential safety hazards associated with rapid pressure fluctuations.

  • Suitable for High-Speed Applications: The HOF series transmitter is well-suited for use in high-speed automation or control systems where fast response to pressure changes is critical.

The Hogller HOF series pressure transmitter is designed to function reliably across a wide range of temperatures:

  • Media Temperature: The transmitter can withstand exposure to media temperatures ranging from -20°C to +100°C. This allows for use in various industrial environments with hot or cold fluids.

  • Compensated Temperature Range: For optimal accuracy, the HOF series is internally compensated to deliver the best performance within a -20°C to +80°C temperature range. Within this compensated range, the transmitter’s internal electronics automatically account for any temperature-induced variations, ensuring accurate pressure readings.

  • Ambient Temperature: The transmitter itself can operate reliably in ambient temperatures ranging from -20°C to +80°C. This allows for use in diverse environments, from cold storage facilities to industrial settings with moderate heat.

  • Storage Temperature: When not in operation, the HOF series can be safely stored in temperatures between -20°C and +100°C. This wide storage range provides flexibility for temporary decommissioning or transportation without compromising the transmitter’s performance.
