Description
Part of the SmartLine® family of products, the SmartLine STT700 is a high performance temperature transmitter offering high accuracy and stability over a wide range of process and ambient temperatures. The STT700 addresses the broadest market applications by providing a temperature transmitter that can meet the bulk of the industrial application needs. The STT700's versatility, including the ability to select single or dual input, HART or DE protocol, with or without display, various mounting configurations, and the ability to connect to 2, 3 or 4-wire sensor types, allows your site to standardize on a single product and thus simplifying support and training.

Indication/Display Option
The STT700 accommodates a Standard alphanumeric LCD display.

Standard LCD Display Features
o Modular (may be added or removed in the field)
o 0, 90, 180 & 270 degree position adjustments
o Deg C, F, R and Kelvin measurement units
o 2 Lines 6 digits PV (9.95H x 4.20W mm), 8 Characters
o Built in Basic Device Configuration through internal buttons - Range/Engineering Unit/Loop Test/ Loop Calibration/Zero-Span Setting
o Write Protect indication

Configuration Tools
Hand Held Configuration
SmartLine transmitters feature two-way communication and configuration capability between the operator and the transmitter. This is accomplished via Honeywell's field-rated Multiple Communication Configuration tool. The Honeywell handheld MC Toolkit is capable of field configuring HART and DE devices and can also be ordered for use in intrinsically safe environments.
All Honeywell transmitters are designed and tested for compliance with the offered communication protocols and are designed to operate with any properly validated handheld configuration device.

Personal Computer Configuration
HART Communicator Model 375, 475 or MC Toolkit for HART 7 Models.
Field Device Manager (FDM) Software and FDM Express are also available for managing HART and DE device configurations (FDC).
Smart Field Communicator (SFC) for DE Models.

Diagnostics
SmartLine transmitters all offer digitally accessible diagnostics which aid in providing advanced warning of possible failure events minimizing unplanned shutdowns, providing lower overall operational costs.

System Integration
o All SmartLine products communications protocols meet all of the most current published standards for HART
o SmartLine STT700 is fully compatible with Honeywell's DE protocol.
