Product Description

General: The ST3000 Ace* Smart Transmitter is a microprocessorbased smart transmitter that features high performance and excellent stability. Capable of measuring absolute pressures of gas, liquid, and vapor, it transmits analog signals of 4 to 20 mA DC and digital signals It can als aoc ecxoerdcuinteg ttwo oth-we amye caosumrmedu pnriceasstiuornes. 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. 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) 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. JTA940A: 35 to 3500 kPa abs (rangeability: 1 to 100) (3) A diverse lineup: • A wide range of models is available to meet user needs for standard and high pressures. • A wide variety of corrosion-resistant materials for wetted parts is also available. (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: • A wide variety of specialized replacement kits is provided to meet customers’ needs when replacing Yamatake-Honeywell 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. Applications: Petroleum/Petrochemical/Chemical: • For measuring pressures and liquid levels in pipes and tanks Electric Power/City Gas/Other Utilities: • For measurement applications that require a high degree of stability and accuracy 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, etc.) conditions Precision Instruments and Equipment: For precision instruments and weather observation equipment that tend to be affected by atmospheric pressure fluctuations caused by typhoons, atmospheric depressions, etc. 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.
