Temperature Measurement

1/1

SMAR offers an array of compact thermometers, thermowells, measurement inserts, transmitters and accessories for all types of process industries such as Oil & Gas, Chemicals, Food & Beverage, Life Sciences, Sugar & Ethanol, Power & Energy.

TT400 Series

Safety Instrumented Systems are designed and used to prevent hazardous events, to protect
people, the environment or prevent damage to process equipments. The SIS project is based on
the damage that a failure can cause. The Smar TT400 HART® SIS is a transmitter mainly intended
for temperature measuring using RTDs or thermocouples, and for SIL2 and SIL3 (redundancy)
levels.

 

• Simple measurement, only one sensor, providing a current output or via communication;
• Differential measurement, two sensors (same type), providing a current output or via
communication;
• Backup measurement, two sensors (same type), providing a current output or via
communication;

TT300 Series

The TT300 temperature transmitter line is a fully digital, accurate, and compact solution
for temperature measurements. The TT300 transmitters accept different types of sensors
with large measurement range, with 2, 3 and 4-wire connections.

 

• ± 0.02% accuracy;
• Built-in thermocouples and RTD’s linearization;
• True non-interactive zero and span;

TT400 WirelessHART

TT400 WirelessHART™ is used in all field applications demanding data wireless transmission.
Smar TT400 WirelessHART™ is a transmitter mainly intended for temperature measuring using
RTDs or thermocouples.

 

• Simple measurement, by using only one sensor;
• Differential measurement, with two sensors (same type);
• Backup measurement, with two sensors (same type);

TT1.0

The TT1.0 is a temperature transmitter extremely versatile, accepting several types of sensors,
like load cells, etc. The same unit may be used for different measuring ranges and different
types of sensors that include a wide variety of RTDs and thermocouples, besides the inputs for
millivolt and resistance.

 

The TT1.0 is the best cost/benefit in its class.

 

TT383

TT383 has independent channels to measure up to 8 (eight) different points. The temperature
information is provided by the Profibus -PA communication protocol and the measurement
can be done via Thermocouples or RTD sensors. Some TT383 features:

 

• 8 (eight) temperature channels for several types of sensors;
• ± 0,03% accuracy;
• 2 or 3 wires sensor connections;
• DD/EDDL and FDT/DTM technologies based;

TT481 WirelessHART

The TT481 WirelessHART™ is a temperature transmitter for 4 or 8 inputs that simplifies the
installation and provides a temperature measurement per point cheaper. Temperature
information is available via WirelessHART™ digital communication protocol. The TT481 offers:

 

• ± 0.03% accuracy;
• RTDs and thermocouples linearization;
• Lightweight and compact;

• Inputs accept 4-20 mA signal for easy integration between 4-20 mA devices to
WirelessHART™ network.

TT421 - Head mount Temperature Transmitter

The TT421 is a temperature transmitter for head mounting, compatible with the HART®
protocol. It works with several sensor types and represents an excellent cost/benefit solution.

 

• 0.02% accuracy;
• Input: a single input accepts signals from thermocouples, RTD’s, differential RTD’s, mV
signals from radiation pyrometers, load cells, Ohm signals from position indicators, etc;

• Measurement types: Single Sensor: 2, 3, or 4 wire; 2-wire double sensor: Differential,
Average; Maximum and Minimum;

TT411 - Panel mount Temperature Transmitter

The TT411 is a panel mount temperature transmitter, compatible with the HART®
protocol. It works with several types of sensors and is an excellent cost/benefit solution.

 

• 0.02% accuracy;
• Input: a single input accepts signals from thermocouples, RTD’s, differential RTD’s, mV
signals from radiation pyrometers, load cells, Ohm signals from position indicators, etc;

• Measurement types: Single Sensor: 2, 3, or 4 wire; 2-wire double sensor: Differential,
Average; Maximum and Minimum;
