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 performanceLong-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 lineupA 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 communicationEither 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.
