TT300 Series are available in three different technologies: HART®(TT301), FOUNDATION FieldbusTM (TT302) and PROFIBUS PA (TT303). These instruments can be configured with Smar software and other manufacturer configuration tools. Local adjustment is available in all TT300 Series. It is possible to configure zero and span, set point and other control functions using the magnetic screwdriver. Smar has developed Asset View, which is a user-friendly Web Tool that can be accessed anywhere and anytime using an Internet browser. It is designed for management and diagnostics of field devices to ensure reactive, preventive, predictive and proactive maintenance.
TT303 (PROFIBUS PA protocol) can be configured using Simatic PDM and by the FDT (Field Device Tool) and DTM (Device Type Manager) concept tools, such as FieldCareTM and PACTwareTM. It can also be integrated by any PROFIBUS System using the GSD file. PROFIBUS PA also has quality and diagnostic information, improving plant management and maintenance.
The TT303 is a transmitter mainly intended for measurement of temperature using RTDs or thermocouples, but can also accept other sensors with resistance or mV output such as: pyrometers, load cells, resistance position indicators, etc.
The digital technology used in the TT303 enables a single device to accept several types of sensors, wide ranges, single-ended or different measurement and an easy interface between the field and the control room and also includes several interesting features that reduce considerably the installation, operation and maintenance costs. The transmitter accepts two channels, i.e., two measurements. This reduces the cost per channel.
