Marketing Information |
STT350 is Honeywell’s high-performance
smart temperature transmitter. The output is transmitted in either an
analog 4-20mA format or Honeywell’s DE protocol format for digital
integration with the Honeywell TPS control system. Select the analog or
digital output format through the Smart Field Communicator (SFC), the
common handheld operator interface for our Smartline™ transmitters, or
with the PC-based SCT 3000 (Smart Configuration Toolkit). All
configuration, operation and communication functions are implemented
remotely from the TPS consoles or through the SFC or SCT.
STT350 transmitters are suitable for new installations as well as
replacements for any conventional or smart temperature transmitters in
use today. The transmitter’s memory contains the characteristics of the
RTD and thermocouple temperature sensors most commonly used. You can
easily use the handheld or PC tool to configure the transmitter for any
of these sensors.
Accuracies stated in the performance specifications below are available
by selecting the sensor type and range (i.e. without user calibration).
Calibration of the LRV/URV end points will typically improve accuracy up
to two times. Sensor errors can be minimized by calibration to the
specific sensor either by setting it at the LRV/URV temperatures or by
simulation of the known values.
Additionally, all units pass through environmental stress screening by
fast cycling between -40 degrees Celsius and 85 degrees Celsius to
ensure maximum product reliability. During this process the ambient
temperature coefficients are determined for each unit and burned into
memory to ensure temperature compensation over a wide range of operating
conditions.
Configuration adjustments and diagnostics checks can be made either
locally or remotely from anywhere along the signal wires. This saves
time during commissioning, startup and maintenance activities. |
