Description
The SmartLine family of gauge pressure, differential pressure, and absolute pressure transmitters is designed around a high performance piezo-resistive sensor. This one sensor actually integrates multiple sensors linking process pressure measurement with on-board static pressure (DP Models) and temperature compensation measurements resulting in the best total performance available. This level of performance allows the ST 800 to replace virtually any competitive transmitter available today.
Unique Indication/Display Options
The ST 800 modular design accommodates a basic alphanumeric LCD display or a unique advanced graphics LCD display with many unparalleled features.
Basic Alphanumeric LCD Display Features
• Modular (may be added or removed in the field)
• 0, 90,180, & 270 degree position adjustments
• Configurable (HART only) and standard (Pa, KPa, MPa, KGcm2, Torr, ATM, inHO, mH2O, bar, mbar, inH2O, inHG, FTH2O, mmH2O, mm HG, & psi) measurement units
• 2 Lines 16 Characters (4.13H x 1.83W mm)
• Square root output indication (√)
Advanced Graphics LCD Display Features
• Modular (may be added or removed in the field)
• 0, 90, 180, & 270 degree position adjustments
• Standard and custom measurement units available.
• Up to eight display screens with 3 formats are possible
(Large PV with Bar Graph or PV with Trend Graph)
• Configurable screen rotation timing (1 to 30 sec)
• Display Square Root capabilities may be set separately from the 4-20mA dc output signal
• Unique "Health Watch" indication provides instant visibility of diagnostics
• Multiple language capability. (EN, DE, FR, IT, ES, RU, TR, CN, JP)
Diagnostics
SmartLine transmitters all offer digitally accessible diagnostics which aid in providing advanced warning of possible failure events minimizing unplanned shutdowns, providing lower overall operational costs
Configuration Tools
Integral Three Button Configuration Option
Suitable for all electrical and environmental requirements, SmartLine offer the ability to configure the transmitter and display via three externally accessible buttons when either display option is selected. Zero/span capabilities are also optionally available via these buttons with or without selection of a display option.
Hand Held Configuration
SmartLine transmitters feature two-way communication and configuration capability between the operator and the transmitter. This is accomplished via Honeywell's field-rated Multiple Communication Configurator (MCT404).
The MCT404 is capable of field configuring DE and HART Devices and can also be ordered for use in intrinsically safe environments. All Honeywell transmitters are designed and tested for compliance with the offered communication protocols and are designed to operate with any properly validated hand held configuration device.
Personal Computer Configuration
Honeywell's SCT 3000 Configuration Toolkit provides an easy way to configure Digitally Enhanced (DE) instruments using a personal computer as the configuration interface. Field Device Manager (FDM) Software and FDM Express are also available for managing HART & Fieldbus device configurations.
System Integration
• SmartLine communications protocols all meet the most current published standards for HART/DE/Fieldbus.
• Integration with Honeywell's Experion PKS offers the following unique advantages.
• Transmitter messaging
• Maintenance mode indication
• Tamper reporting
• FDM Plant Area Views with Health summaries
• All ST 800 units are Experion tested to provide thehighest level of compatibility assurance
Modular Design
To help contain maintenance & inventory costs, all ST 800 transmitters are modular in design supporting the user's ability to replace meter bodies, add indicators or change electronic modules without affecting overall performance or approval body certifications. Each meter body is uniquely characterized to provide in-tolerance performance over a wide range of application variations in temperature and pressure and due to the Honeywell advanced interface, electronic modules may be swapped with any electronics module without losing intolerance performance characteristics.
Modular Features
• Meter body replacement
• Exchange/replace electronics/comms modules*
• Add or remove integral indicators*
• Add or remove lightning protection (terminal connection)*
* Field replaceable in all electrical environments (including IS) except flameproof without violating agency approvals.
With no performance effects, Honeywell's unique modularity results in lower inventory needs and lower overall operating costs
Plugged Impulse Line Detection:
STG800 models are offered with a PILD option which provides indication of a plugged impulse line or process connection. When used in conjunction with a basic or advanced display, a non-critical diagnostic indication appears on the integral display. For units without an integral display, an indication can be seen via the host or hand held device when HART Protocol is utilized.
Dual/Triple Calibration:
STG800 models are optionally offered with multiple calibrations. In lieu of a standard factory calibration, units can be supplied with 1, 2, or 3 customer specified calibrations. These calibrations are stored in the meter body and provide users with factory calibrated performance at up to three different calibrated ranges. This increases application flexibility without requiring any costly recalibration or additional inventory.
