SmartLine^® Temperature Transmitters

STT650

The SmartLine STT650 DIN rail mounted temperature transmitters offer high measurement accuracy, stability and reliability over a wide range of process and ambient temperatures.Their compact designs, along with dual channel options, help accommodate multiple temperature measurements on a panel, thus lowering both costs and inventory. Designed to deliver very high performance, the SmartLine STT650 easily meets the most demanding needs for temperature measurement, allowing it to replace virtually any transmitter available today.

Features:

• High accuracy – 0.1°C for RTD
• Faster response, up to 135 ms update
• Stable measurement, 0.12% of span for two years
• Built-in 1500 VAC galvanic isolation
• Superior noise performance – tested for 2 KV surge/2.5 kv burst noise
• Sensor diagnostics
• Simple and easier configuration
• Compact design, saving over 50% panel space.

STT700

The STT700 is an exciting new addition to the SmartLine Temperature portfolio and upgrades the widely-used STT250 temperature transmitter.  The STT250 has been Honeywell’s main temperature transmitter with many decades of in-field use.  The STT700 is a direct replacement for the STT250 and thus is suitable for the majority of process applications including those for control and safety while delivering excellent performance at a low installed cost.

Features:

• SmartLine platform features including SmartLine Connection Advantage when used with Experion
• Single input supporting up to 4-wire RTD sensor connection
• Dual input option supporting up to two (2) 3-wire RTD sensor connections
• Digital accuracy up to 0.15°C for RTD
• Callendar-Van Dusen sensor constants input
• HART7 communications
• DE communications
• Field housing, head mount, panel mount and DIN rail mounting options
• Transmitter and sensor diagnostics
• FM / CSA / ATEX / IEC Ex approvals
• Full compliance with SIL 2 / 3 requirement
• Up to a 4-year warranty

STT750

The STT750 Temperature Transmitters are intended to be a competitive replacement for the STT250 HART field mount temperature transmitters. Suitable for a wide range of control and safety applications, the transmitters provide users with the benefits of the SmartLine platform, including modularity, easier maintenance and lower total cost of ownership.

Features:

• Single universal input
• Digital accuracy up to 0.14°C for RTD
• Easy-to-use-and-read basic display
