Product Name: Remote-sealed type of Differential Pressure Transmitters Model STE929 / STE930

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, and liquid levels, it transmits 4 to 20 mA DC analog and digital signals according to the measured differential 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. Remote-sealed differential pressure transmitters are suitable for the measurement of differential pressures (flow rates, liquid levels, etc.) of process fluids that are highly corrosive, tend to condense, precipitate metal, etc. FEATURES: - 1)Excellent stability and high performance: • Long-term stability is proven in 500,000 installations worldwide. • Unique characterization and composite semiconductor sensors realize excellent temperature and static pressure characteristics. 2)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 range of models, including those for general purposes, high-temperature, and high temperature and high-vacuum service, is available to meet user requirements. In addition, the working temperature range of general purpose models has been expanded to 180°C maximum to allow you greater freedom instrumentation. • A wide variety of corrosion-resistant materials for wetted parts is also available. 3)Function to correct the temperature of the fill fluid of the capillary section: Changes in the density of the fill fluid caused by temperature fluctuations are calculated, and the output is corrected accordingly. This function substantially reduces (to 1/5 - 1/10) the effect of seasonal fluctuations in temperature. 4)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: - Petroleum / Petrochemical / Chemical: • For the measurement of liquid levels including corrosive fluids at high temperatures, and high temperatures under vacuum. • For the control of flow rates as used with tapless venturi tubes. • For replacement of displacement type level gauges. • For materialization of instrumentation without connecting tubes. Electric power / City gas / Other utilities: For measurement applications that require high degrees of stability and accuracy. Pulp and paper: • For lines that need transmitters resistant to chemical liquids, corrosive fluids and the like • For the measurement of liquid levels in small tanks • Iron and Steel / Nonferrous metal / Ceramics • For lines that require stable measurement under strictly controlled (temperature, humidity, etc.) conditions Iron and steel / Nonferrous metal / Ceramic: For lines that require stable measurement under strictly controlled (temperature, humidity, vibration, etc.) conditions. Machinery / Shipbuilding: For lines that require stable measurement under strictly controlled (temperature, humidity, etc.) conditions.
