Product Name: Differential Pressure Transmitters JTE929A/JTE930A

Product Description

General: - The ST3000 Ace* Smart Transmitter is a microprocessorbased smart transmitter that features high performance and excellent stability. Capable of measuring gas, liquid, and vapor flow rates, 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), 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 has been 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 1.5in.(40mm) and 2in. (50mm) to 3in. (80mm), is available to meet user requirements. • A wide range of models, including those for general purpose and high-temperature 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 in instruction. • A wide variety of corrosion-resistant materials for wetted parts is also available. • These differential pressure transmitters can be mounted in various ways, including direct mounting on tanks without using 2in. stanchion pipes. (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 output is corrected ac cordingly.This function substantially reduces (to 1/5—1/10) the effect of seasonal fluctuations in temperature. (4) Multiprotocol communication • Either analog output (4 to 20 mA DC), analog FSK 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. (5) Full after-sales service program • From product delivery to replacement, we will service all your needs. Our nationwide service network provides all the backup you require, including trial operation support and regular maintenance. Applications: - 1)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 2)Electric Power/City Gas/Other Utilities • For measurement applications that require a high degree of stability and accuracy 3)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 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, vibration, etc.) conditions
