OVERVIEW
The ST3000 Smart Transmitter is a microprocessor-based smart transmitter that features high performance and excellent stability. Capable of measuring gas, liquid, and vapor, and liquid levels, it transmits 4 to 20 mA DC analog and digital signals according to the measured pressure. It can also execute two-way communications between the SFC (Smart Field Communicator) or HART® 375 communicator, and, via DE protocol, with the TDCS3000 or 3000X and a database, thus facilitating self-diagnosis, range resetting, and automatic zero adjustment.

FEATURES
Excellent stability and high performance
• Long-term stability is proven in 1,000,000 installations worldwide.
• Unique characterization and composite semiconductor sensors realize excellent temperature and static pressure characteristics.

Wide measuring range (range ability)
• A wide measuring range is available from a single model. This feature is highly effective in taking measurement over a wide range and reducing the need for inventory.
• Model STD920: 0.75 to 100 kPa (rangeability: 133 to 1)

A diverse lineup
• A wide range of models is available to meet user requirements. They include draft range 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.

Remote communication
• Either analog 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.
• HART® protocol communication is available. (Option)
HART® is a registered trademark of the HART Communication Foundation.

APPLICATIONS
Petroleum/Petrochemical/Chemical
• For strict flow control in combination with orifice plates.

Electric power/City gas/Other utilities
• For measurement applications that require high degrees of stability and accuracy.

Draft range applications such as Semiconductor Equipment Manufacturing /Clean Rooms
• For applications that require highly stable, accurate measurement.

Pulp and paper
• For lines that need transmitters resistant to fluid such as chemical liquids and corrosive fluids.

Iron and steel/Nonferrous metal/Ceramics
• For highly stable, accurate measurements such as furnace pressure measurement.
• 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)
