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, etc.) conditions.
