Product Name: Flange type of Differential Pressure Transmitter Model STC929 / STC940

Product Description

OVERVIEW The ST3000 Smart Transmitter is a microprocessor- based smart transmitter that features high performance and excellent stability. Capable of measuring gas, liquid, and vapor flow rate, pressure, and liquid levels, it transmits 4 to 20 mA DC analog and digital signals according to the measured pressure. It can also execute two-way communications between the SFC (Smart Field Communicator) or HART® 275 communicator, and, via DE protocol, with the TDCS3000 or 3000X and a database, thus facilitating self-diagnosis, range resetting, and automatic zero adjustment. Flanged differential pressure transmitters mounted on tank sides are suitable for the measurement of liquid levels, boundary surface levels, and specific gravity. FEATURES: - Excellent stability and high performance: • Long-term stability is proven in 500,000 instal-lations worldwide. • Unique characterization and composite semi-conductor sensors realize excellent temperature and static pressure characteristics. A diverse lineup: • A diverse flange lineup, ranging from small diameter 1.5 inch (40 mm) and 2 inches (50 mm) to 3 inches (80 mm), is available to meet user requirements. • A wide variety of models, including those for standard differential pressure and high differential pressure, is available to meet user requirements. • A wide variety of corrosion-resistant materials for wetted parts is also available. Remote communication: • Either analog output (4 to 20 mA DC), or digital output (DE protocol) is possible. • Two-way communication using digital output facilitates self-diagnosis, range resetting, automatic zero adjustment, and other operations. •HART® protocol communication is available.(Option) APPLICATION: - 1)Petroleum / Petrochemical / Chemical: For measuring pressures, liquid levels, and ordinary surfacelevels in tanks of all sizes. 2)Electric power / City gas / Other utilities: For measurement applications that require high degrees of stability and accuracy. 3)Pulp and paper: • For lines that need transmitters resistant to chemical liquids, corrosive fluids and the like. • For measuring pressures, liquid levels, and boundary surface levels in tanks • For measuring pressure, liquid levels, and boundary surface levels in tanks of all sizes. 4)Iron and steel / Nonferrous metal / Ceramics: For lines that require stable measurement under strictly controlled (temperature, humidity, etc.) conditions. 5)Machinery / Shipbuilding: For lines that require stable measurement under strictly controlled (temperature, humidity, etc.) conditions.
