TT300 Series offers:
• ± 0.02% accuracy;
• Built-in thermocouples and RTDs linearization;
• Compact and lightweight;
• Interchangeable protocols.

The Smar TT300 Series is a transmitter mainly intended for measurement of temperature using RTDs or thermocouples.  However, it can also accept other sensors with resistance or mV output such as  pyrometers, load cells, resistance position indicators, etc. The TT300 Series accepts up to two sensors and may operate in one of the modes below*:
• Single channel with single sensor measurement;
• Dual channel with dual sensor measurement (except HART protocol device);
• Single channel with two sensors (same type) in differential measurement;
• Single channel with two sensors (same type) in backup measurement;
• Single channel with two sensors (same type) with maximum, minimum or average signal selection (only HART protocol device).

Safety Instrumented Systems are designed and used to prevent or mitigate hazardous events to protected people, the environment or prevent damage to process equipment.  The SIS project is based on the damage that a failure can cause.
The 2 (non-redundant) and SIL 3 (redundant) applications, and intendeds for measurement of temperature using RTD’s or thermocouples. Also, operating in one of the models listed below:
Single channel with single sensor measurement;
Single channel with two sensors (same type) in differential measurement;
Single channel with two sensors (same type) in backup measurement;
Single channel with two sensors (same type) with maximum, minimum or average signal selection.
The digital technology used in the single device to accept several types of sensors, wide ranges, single or multiple-ended measurement and an easy interface between the features which reduce considerably the installation, operation and maintenance costs.
