Product DescriptionProduct DescriptionHoneywell STD730 Differential Pressure TransmitterThe Honeywell STD730 is a high - performance differential pressure transmitter that belongs to the SmartLine family of products. It is designed to meet the demanding requirements of various industrial applications, providing accurate and reliable differential pressure measurement. With advanced piezoresistive sensor technology and a range of intelligent features, the STD730 offers enhanced performance, stability, and flexibility in different operating conditions.The STD730 employs piezoresistive sensor technology, which is based on the principle that the electrical resistance of certain materials changes when mechanical stress is applied. In this case, the sensor consists of a silicon diaphragm with piezoresistive elements diffused onto it. When a differential pressure is applied across the diaphragm, it deflects, causing a change in the resistance of the piezoresistive elements. This change in resistance is then converted into an electrical signal proportional to the differential pressure.To ensure accurate measurement over a wide temperature range, the STD730 incorporates on - chip temperature compensation capabilities. A built - in temperature sensor continuously monitors the temperature of the sensor and its surroundings. The transmitter's microprocessor uses this temperature data to adjust the pressure measurement signal, compensating for any temperature - induced errors. This results in highly stable and accurate measurements, even in environments with significant temperature variations.1. Key Features1.1 High AccuracyThe STD730 offers an impressive accuracy of up to 0.05% of span. This high level of accuracy ensures that the measured differential pressure values are extremely precise, making it suitable for applications where accurate pressure measurement is crucial, such as in custody transfer, where the accurate measurement of fluid flow based on differential pressure is essential for fair trade.1.2 Long - Term StabilityWith a stability of up to 0.020% of URL (Upper Range Limit) per year for 10 years, the STD730 provides reliable and consistent performance over an extended period. This long - term stability reduces the need for frequent calibration and maintenance, resulting in lower operating costs and increased process uptime.1.3 Automatic Static Pressure and Temperature CompensationThe transmitter automatically compensates for static pressure and temperature changes. This feature is particularly important in applications where the process fluid's temperature or the static pressure in the system can vary significantly. By compensating for these factors, the STD730 maintains accurate differential pressure measurement, regardless of changes in the operating conditions.1.4 Wide RangeabilityFeaturing a rangeability of up to 100:1, the STD730 can measure differential pressures over a wide range. This means that it can be configured to accurately measure both very small and very large differential pressure values within its overall measurement range. For example, it can be set to measure a minimum span of 1 psi (0.07 bar) and a maximum span of 100 psi (7.0 bar), providing great flexibility in application scenarios.1.5 Fast Response TimeThe STD730 has a response time as fast as 100ms. This quick response allows it to rapidly detect changes in differential pressure, making it suitable for applications where real - time monitoring and control are required. In processes such as high - speed fluid flow control or in systems where rapid pressure fluctuations need to be tracked, the fast response time of the STD730 ensures that the control system can react promptly to maintain optimal process conditions.2. Technical Specifications2.1 Measurement RangeThe STD730 has a measurement range of - 100 to +100 psi (-7.0 to +7.0 bar). The lower range limit (LRL) is - 100 psi (-7.0 bar), and the upper range limit (URL) is +100 psi (+7.0 bar). The maximum span it can measure is 100 psi (7.0 bar), and the minimum span is 1 psi (0.07 bar). This wide measurement range makes it applicable to a diverse range of industrial processes, from low - pressure applications in the food and beverage industry to medium - pressure applications in chemical and petrochemical plants.2.2 Output SignalThe standard output signal of the STD730 is a two - wire 4 - 20mA DC analog signal. This analog signal is proportional to the measured differential pressure. In addition to the analog output, the transmitter also supports digital communication protocols. It can communicate using the HART (Highway Addressable Remote Transducer) protocol, which allows for the transmission of additional information such as diagnostic data, configuration settings, and the measured pressure value in digital form. Some models of the STD730 also support the FOUNDATION Fieldbus protocol, which is a digital communication standard widely used in industrial automation systems for more complex and high - speed data communication requirements.2.3 Power SupplyThe STD730 typically requires a power supply voltage in the range of 12 - 42V DC. The power supply is connected to the transmitter through a two - wire connection, which also serves as the communication path for the 4 - 20mA output signal and digital communication (if applicable). The wide power supply voltage range makes it compatible with different power sources in industrial settings, and the ability to operate on a relatively low - voltage power supply helps to reduce energy consumption and simplifies the power distribution system.2.4 Process ConnectionThe process connection of the STD730 is usually a 1/2"NPT (National Pipe Thread) female connection. This standard connection type allows for easy installation and connection to various process piping systems. The materials used for the process connection, such as the connection body and the sealing gasket, can be selected based on the application requirements. Common materials include 316 stainless steel and 316L stainless steel, which offer good corrosion resistance in many industrial environments.SpecificationMeasurement RangeUp to 6 m (20 ft) (probe-dependent)Accuracy±3 mm (±0.12 in)Process Temperature-196°C to +400°C (-320°F to +752°F)Process Pressure100 bar (1450 psi)Probe TypesSingle-rod, Twin-rod, Coaxial cableOutput Signals4-20 mA HART, PROFIBUS PA, Foundation FieldbusPower Supply10.5-42 V DC (loop-powered)Housing ProtectionIP66/IP67, NEMA 4XCompany ProfileKeRui (Weifang) Automation Equipment Co.
