Product Name: JTH Series of Remote-sealed Type Pressure Transmitters JTH920A/JTH940A/JTH960A/JTH980A

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 pressures, and liquid levels, it transmits 4 to 20 mA DC analog and digital signals It can a caclsoor deixnegc utote t htwe om-weaasyu rceodm pmreusnsuicraet.i ons 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 pressure transmitters are suitable for the measurement of pressures (pressures, 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 instrumentation. • A wide variety of corrosion-resistant materials for wetted parts is also available. (3) 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. (4) Full after-sales service program: • Fryoomur pnreoeddus.c t Odeulri vneartyio tnow riedpel asceervmicene tn, ewtwe owrikl lp sreorvviidcees a alll l the backup you require, including trial operation support and regular maintenance. Applications: - Petroleum/Petrochemical/Chemical • For the measurement of liquid levels including corrosive fluids at high temperatures, and high temperatures under vacuum. • For the measurement of liquid levels in small tanks Electric Power/City Gas/Other Utilities • For measurement applications that require a high degree 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 Machinery/Shipbuilding • For lines that require stable measurement under strictly controlled (temperature, humidity, vibration, etc.) conditions Specifications: - Output/communication: Analog output (4 to 20 mA DC) Analog FSK output (4 to 20 mA DC) (Frequency shift keying signal transmission system) Digital output (DE protocol) Supply voltage and load resistance: 10.8 to 45 V DC. A load resistance of 250 or more is necessary between loops. Sealing liquid: Silicone oil for general purpose and: high-temperature models Fluorine oil for oxygen and chlorine models For specific gravity, Ambient temperature ranges: except for explosion-proof models with digital indicators, which have to be used within the following ranges: Ambient humidity range:5 to 100% RH Stability against supply voltage change:±0.005% FS/V Lightning protection: Peak value of voltage surge: 100 kV Peak value of current surge: 1000 A Dead time: Approx. 0.4 sec
