Whether you're considering upgrading your existing pressure measurement equipment or seeking a solution for a new project, understanding the capabilities of the Honeywell ST800 can help you make an informed decision for your specific needs.

Advanced Sensor Technology and Accuracy

Innovative Sensor Design

At the heart of the Honeywell ST800 Pressure Transmitter lies its innovative sensor technology. The device utilizes a piezoresistive sensing element, which is renowned for its stability and precision. This sensor is fabricated using advanced micromachining techniques, resulting in a compact yet highly sensitive measurement unit. The piezoresistive element responds to pressure changes by altering its electrical resistance, which is then converted into a precise pressure reading. This technology allows the ST800 to maintain its accuracy even in challenging industrial environments where temperature fluctuations and vibrations are common.

Exceptional Measurement Accuracy

One of the standout features of the Honeywell ST800 is its exceptional measurement accuracy. The transmitter boasts an industry-leading accuracy of up to ±0.0375% of span, depending on the specific model and configuration. This high level of precision is crucial for applications where even minor deviations in pressure readings can have significant consequences. The ST800's accuracy is not just a static specification; it maintains this level of performance over a wide range of operating conditions, including varying temperatures and pressures. This consistency is achieved through sophisticated compensation algorithms that account for environmental factors, ensuring reliable measurements in diverse industrial settings.

Wide Rangeability and Turndown Ratio

The Honeywell ST800 Pressure Transmitter offers impressive rangeability, with a turndown ratio of up to 400:1. This means that a single transmitter can accurately measure pressures across a wide span, reducing the need for multiple instruments in applications with varying pressure ranges. The high turndown ratio also contributes to improved inventory management for facilities, as fewer transmitter models are required to cover a broad range of measurement needs. This versatility makes the ST800 an economical choice for complex systems where pressure conditions can fluctuate significantly.

Robust Design and Durability

Rugged Construction for Harsh Environments

The Honeywell ST800 Pressure Transmitter is built to withstand the rigors of industrial environments. Its housing is constructed from durable materials, typically stainless steel or aluminum, depending on the specific model. This robust construction provides excellent protection against physical impacts, corrosive substances, and extreme weather conditions. The transmitter's enclosure meets stringent IP66/67 ratings, ensuring dust-tight protection and the ability to withstand powerful water jets or temporary immersion. This level of protection is essential for maintaining the integrity of the sensor and electronics in outdoor installations or in areas prone to wash-down procedures.

Wide Operating Temperature Range

Another key feature of the ST800 is its ability to function reliably across a wide range of temperatures. The transmitter is designed to operate in environments ranging from -40°C to 85°C (-40°F to 185°F) for most models. This broad temperature range makes the ST800 suitable for use in diverse applications, from cryogenic processes to high-temperature industrial operations. The transmitter's internal temperature compensation ensures that accuracy is maintained even when subjected to significant temperature variations, a critical factor in maintaining process stability and product quality in temperature-sensitive applications.

Resistance to Electromagnetic Interference

In modern industrial settings, electromagnetic interference (EMI) can pose a significant challenge to the accuracy and reliability of electronic instruments. The Honeywell ST800 is engineered with advanced EMI protection features to ensure consistent performance in electrically noisy environments. The transmitter's circuitry includes filters and shielding designed to mitigate the effects of electromagnetic fields generated by nearby equipment such as motors, transformers, and radio frequency sources. This robust EMI resistance helps maintain signal integrity and measurement accuracy, even when installed in close proximity to potential sources of electrical interference.

User-Friendly Features and Connectivity

Intuitive Configuration and Diagnostics

The Honeywell ST800 Pressure Transmitter is designed with user-friendliness in mind, offering intuitive configuration options and comprehensive diagnostic capabilities. The transmitter can be easily set up using a handheld communicator, such as the Honeywell Field Device Manager, or through digital communication protocols like HART. The user interface provides clear menus and prompts, allowing technicians to quickly adjust parameters such as measurement range, units, and damping. Additionally, the ST800 incorporates advanced self-diagnostic features that continuously monitor the transmitter's health and performance. These diagnostics can alert operators to potential issues before they become critical, enabling proactive maintenance and reducing downtime.

Versatile Communication Protocols

In today's interconnected industrial landscape, flexible communication options are essential. The Honeywell ST800 supports multiple industry-standard protocols, including HART, FOUNDATION Fieldbus, and PROFIBUS PA. This versatility allows seamless integration with a wide range of control systems and asset management platforms. The ability to communicate digitally enables remote configuration, monitoring, and troubleshooting, reducing the need for physical access to the transmitter in challenging or hazardous locations. Furthermore, the digital communication capabilities facilitate the implementation of advanced process control strategies and predictive maintenance programs, enhancing overall plant efficiency and reliability.

Enhanced Safety Features

Safety is paramount in industrial applications, and the Honeywell ST800 incorporates several features to enhance operational safety. The transmitter is available with intrinsically safe and explosion-proof certifications, making it suitable for use in hazardous areas. For critical applications, the ST800 can be configured with Safety Integrity Level (SIL) 2 certification, ensuring compliance with stringent functional safety requirements. The transmitter also includes overpressure protection, safeguarding the sensor against damage from pressure spikes. These safety features, combined with the device's reliable performance, contribute to improved process safety and reduced risk of incidents in potentially dangerous industrial environments.

Conclusion

The Honeywell ST800 Pressure Transmitter stands out as a versatile and reliable solution for industrial pressure measurement.
