honeywell st800 manual and datasheet

The STA800 SmartLine Absolute Pressure transmitter is a high-performance device that utilizes piezoresistive sensor technology for accurate and stable pressure measurement. It offers several best-in-class features, including:

1. Accuracies: The transmitter provides standard accuracies up to 0.0375% of span, with an optional accuracy of 0.025% of span.
2. Stability: It offers stability up to 0.01% of URL (Upper Range Limit) per year for 15 years, ensuring long-term performance.
3. Temperature Compensation: The transmitter has on-chip temperature compensation capabilities, automatically compensating for changes in temperature to maintain accuracy.
4. Rangeability: It offers a rangeability of up to 100:1, allowing for flexibility in measuring a wide range of pressures.
5. Response Times: The STA800 provides fast response times as quick as 80ms, enabling real-time pressure monitoring.
6. Local Display: The transmitter supports multiple local display options, allowing for easy viewing of pressure measurements.
7. External Configuration: It offers external zero, span, and configuration capabilities, providing flexibility in adjusting the device settings.
8. Polarity Insensitive Electrical Connections: The transmitter’s electrical connections are polarity insensitive, simplifying the installation process.
9. Diagnostic Capabilities: It has comprehensive on-board diagnostic capabilities, providing advanced warning of possible failure events and minimizing unplanned shutdowns.
10. Safety and Compliance: The STA800 features an Integral Dual Seal design, ensuring the highest level of safety based on ANSI/NFPA 70-202 and ANSI/ISA 12.27.2 standards. It is also fully compliant with SIL 2/3 requirements.
11. Modular Design: The transmitter follows a modular design approach, allowing for easy customization and configuration based on application needs.
12. Warranty: An additional 15-year warranty option is available for the STA800.
13. Plugged Impulse Line Detection Option: The transmitter can be equipped with a plugged impulse line detection option for enhanced monitoring and maintenance.
14. Dual/Triple Calibration Option: This option is available for HART and Fieldbus configurations, allowing for calibration flexibility.

The STA800 offers various display options, including a basic alphanumeric LCD display and an advanced graphics LCD display with unique features. The alphanumeric display is modular and can be adjusted in multiple positions, while the graphics display offers more flexibility with screen rotation timing and square root capabilities.

The transmitter provides diagnostic features for advanced warning of possible failures, reducing operational costs and minimizing unplanned shutdowns. Configuration can be done through integral three-button configuration options, handheld configuration devices, or personal computer configuration using Honeywell’s SCT 3000 Configuration Toolkit.

In terms of system integration, SmartLine transmitters meet the most current standards for HART/DE/Fieldbus communication protocols. Integration with Honeywell’s Experion PKS offers additional advantages, such as transmitter messaging, maintenance mode indication, tamper reporting, FDM Plant Area Views with health summaries, and compatibility assurance.

Please note that this information is based on the provided specifications, and for more detailed technical information, it’s recommended to refer to the specific product documentation or contact Honeywell for further assistance.

Modular Design

The ST 800 transmitters have a modular design, which provides several benefits in terms of maintenance and inventory management. The modular features include:

1. Meter Body Replacement: Users have the ability to replace meter bodies without affecting the overall performance or certifications of the transmitter. This allows for easy maintenance and customization based on application requirements.
2. Exchange/Replace Electronics/Comms Modules: The electronic modules of the transmitter can be exchanged or replaced without losing the in-tolerance performance characteristics. This flexibility enables easy upgrades or changes to meet evolving needs.
3. Add or Remove Integral Indicators: The transmitter supports the addition or removal of integral indicators as per user requirements. This allows for customization of the display capabilities based on the specific application.
4. Add or Remove Lightning Protection: Users can add or remove lightning protection for the terminal connections, providing flexibility in protecting the transmitter from potential electrical surges. This feature is field replaceable in all electrical environments, except flameproof, without violating agency approvals.

Honeywell’s unique modularity ensures that these features can be implemented without impacting performance or certifications. This modularity not only simplifies maintenance and customization but also helps reduce inventory needs and overall operating costs.

It’s important to note that while the modularity of the ST 800 transmitters offers significant benefits, it is essential to follow the manufacturer’s guidelines and instructions when replacing or modifying any components to maintain safety and compliance with relevant certifications and standards.
