Product Description

General:- The ST3000 Ace* Smart Transmitter is a microprocessorbased smart transmitter that features high performance and excellent stability. Capable of measuring pressures of gas, liquid, and vapor, and liquid levels, it transmits analog signals of 4 to 20 mA DC and digital signals acc It can also execuoter dtiwnog- twoa tyh ec ommemasuunreicda tpiroensss ubreet.w een 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 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. JTG940A: 35 to 3500 kPa (rangeability: 1 to 100) (3) A diverse lineup: • A wide range of models is available to meet user needs for low, 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 application 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 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 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.
