Product Description As a member of the SmartLine? product line, the STD700 is a high-performance differential pressure transmitter that utilizes advanced sensor technology. By combining differential pressure measurements with static pressure and temperature compensation on the sensor chip, the STD700 offers exceptional measurement accuracy and stability across a wide range of static pressures and temperatures. SmartLine? has been thoroughly tested and meets the Experion? PKS standards, ensuring high levels of compatibility and integration capability. SmartLine? products are designed to meet the stringent demands of pressure measurement applications with ease. Innovative Features:Calibration range accuracy up to 0.05%, with 0.04% optionalStability: 0.020% of span, maintained for 10 yearsAutomatic static pressure and temperature compensationRange ratio of 100:1Fast response time of up to 100 msEasy-to-use and intuitive display functionsExternal zero, span, and configuration functionsComprehensive self-diagnosticsIntegrated dual-seal design based on ANSI/NFPA 70-202 and ANSI/ISA 12.27.0 standards to ensure maximum safetyExceptional static pressure tolerance: 31.5 MPaStandard configuration fully meets SIL2/3 requirementsModular designExtendable warranty up to an additional 4 yearsNote: All data provided by Honeywell laboratoriesDescription:The SmartLine? series pressure transmitters are designed based on high-performance sensors. Each sensor effectively integrates multiple sensors, combining process pressure measurement with static pressure (for DP models) and temperature measurement used for temperature compensation, thereby achieving superior overall performance. Display Head OptionsStandard LCD Display Head:Modular (can be added or removed on-site)Supports HART protocolAdjustable to 0°, 90°, 180°, and 270° positionsMeasurement units include: Pa, kPa, MPa, kg/cm2, Torr, ATM, i4H2O, mH2O, bar, mbar, inH2O, inHg, FT H2O, mmH2O, mmHg, and psiLarge screen display (9.95 mm high x 4.20 mm wide) with 2 lines and 8 charactersSquare root output and write protection indicatorDisplay module features internal configuration buttons for setting and calibrating the transmitter via internal or external keysSelf-Diagnostics:SmartLine? transmitters all offer digitally accessible diagnostics, which help provide advanced alarms for potential fault events. This significantly reduces planned downtime and lowers overall operating costs.Configuration ToolsIntegrated Internal or External Configuration Button Options:Transmitters can be configured for all basic parameters using buttons integrated within the display module or external magnetic keys. The integrated external buttons meet all electrical and environmental requirements. For zero/span setting functions, external buttons can be used regardless of whether an LCD display head is selected.Handheld Configuration:SmartLine? transmitters support bidirectional communication and configuration between the operator and the transmitter. This is achieved through Honeywell's field configuration toolkit. Honeywell's field configuration toolkit allows for the on-site configuration of HART transmitters and can be used in intrinsically safe environments. All Honeywell transmitters are designed and tested to comply with the provided communication protocols and can be used with any certified handheld configurator.Computer Configuration:HART Field Device Manager (FDM) software and FDM Express can be used to manage the configuration of devices.System Integration:SmartLine? communication protocols comply with the latest HART standards.All SmartLine? transmitter devices have been tested with Experion?, ensuring high compatibility.Modular Design:To help control maintenance and inventory costs, all ST700 transmitters feature a modular design, allowing for easy hardware replacements such as adding an LCD display head, replacing electronic modules, or even changing the transmitter diaphragm, without affecting overall performance or equipment safety certification. Each transmitter diaphragm is uniquely characterized and calibrated to provide exceptional performance across a wide range of static pressures and temperatures. Additionally, with Honeywell's modular interface design, electronic modules can be interchanged without compromising performance specifications. Diaphragm ReplacementAddable or Removable LCD Display Head*Replaceable Surge Protection Module (Terminals)**Except in explosion-proof environments, on-site replacements can be performed in any electrical environment (including intrinsically safe areas) without violating safety certification regulations.Honeywell's innovative modular design reduces inventory requirements and maintenance costs without affecting transmitter performance.Product ParametersPerformance Under Rated ConditionsParametersDescriptionAnalog OutputDigital CommunicationTwo-wire, 4mA ~ 20 mA.
