Product Name

Smart Temperature Transmitter

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.

Features

  • Direct digital integration with TDC 3000X system provides local measurement accuracy to the system level without adding typical A/D and D/A converter inaccuracies.
  • Integral analogue or digital indicating meter option
  • Single model accepts input signals from a choice of primary sensors to satisfy varying applications requirements with minimum transmitter inventory.
  • Standard digital cold-junction compensation function provides accurate and reliable temperature measurement over a wide ambient operating range.
  • Added Smart features include reading of the highest and lowest inputs, external cold junction compensation temperature at an isothermal block and engineering units displayed in degrees C, F, K, or R plus milliVolt and Ohms.
  • Smart transmitter personality with local or remote interfacing means significant manpower efficiency improvements in commissioning, start-up, and ongoing maintenance functions. Write protect link included to safeguard configuration settings.
  • Includes sensor break detection on all input wires.
  • Post read validation of the measured signal before providing fresh output.
  • Suitable for DIN rail mounting or remote field mounting in a flameproof housing.
  • Provides true differential temperature measurement of thermocouple or RTD inputs by individual linearisation of each sensor reading and then computing the difference.
  • Suitable for true 4-wire Pt100 measurement (or 3- or 2-wire).
  • Write protect link included to safeguard configuration settings.
  • Supports dual thermocouple sensor inputs for redundant sensor operation.
  • Surge/ lightning protection options can be installed internally in housing or externally in conduit.
  • Supply 11-42 Vdc / Output 4-20 mA
  • Temp. Limits -40 to +85ºC
