TT400SIS Smart Temperature Transmitter

The SMAR TT400SIS is a powerful and extremely versatile smart temperature transmitter. The digital technology used in the TT400SIS enables a single device to accept several types of sensors, wide ranges, single or multiple-ended measurement and an easy interface between the field and the control room. It 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.

The TT400SIS is suitable for direct field installation, being weather proof and explosion proof, as well as intrinsically safe, for use in hazardous areas.

The TT400SIS is certified to IEC61508 for SIL 1 and SIL 2 (non-redundant) and SIL 3 (redundant) applications.

he SMAR TT400SIS is a transmitter mainly intended for measurement of temperature using RTD’s or thermocouples.

The TT400SIS accepts up to two sensors and may operate in one of the models.

  • 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.
