JTD Series of Differential Pressure Transmitters ModelJTD910A/920A/930A/960A/921A/931A/961A OVERVIEW The ST3000 Ace Smart Transmitter is a microprocessor-based smart transmitter that features high performance and excellent stability. Capable of measuring gas, liquid, and vapor flow rates, pressures, 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 Smart communicator and via DE protocol with the TDCS3000 or 3000X, or Advanced-PS, and a database, thus facilitating self-diagnosis, range resetting, and automatic zero adjustment. Refer to No. SS2-DST10F-0100 for FOUNDATIONTM Fieldbus specification. FEATURES Excellent stability and high performance • Long-term stability has been proven in 2,000,000 installations worldwide. • Unique characterization and composite semiconductor sensors realize excellent temperature and static pressure characteristics. Wide measuring range (rangeability) • A wide measuring range is available from a single model. This feature is highly effective in taking measurements over a wide range and reducing the need for reserve units. The measuring range of the model JTD920A, for example, is 0.75 to 100 kPa (range ability = 1: 135). A diverse lineup • A wide range of models is available to meet user requirements. They include micro-differential pressure, standard differential pressure, high differential pressure, standard differential pressure/high static pressure, and high differential pressure/high static pressure models. • A wide variety of corrosion-resistant materials for wetted parts is also available. Multi protocol communication • Either analog output (4 to 20 mA DC, SFN protocol, HART® protocol) or digital output (DE protocol, FOUNDATIONTM Fieldbus protocol) is possible. • Two-way communication using SFN, HART, or Foundation Fieldbus facilitates selfdiagnosis, range resetting, automatic zero adjustment, and so on. Full after-sales service program • A wide variety of specialized replacement kits is provided to meet customers' needs when replacing Azbil Corporation’s transmitters or transmitters from other companies. • 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.
