The optical, microprocessor-based temperature transmitter as rugged as it is accurate

RTT15S industrial-grade circuits and sealed electronics deliver accurate, repeatable results in virtually any environment.

The Model RTT15S is a microprocessor-based temperature transmitter that uses the HART® communication protocol. It receives input signals from thermocouples, RTDs, ohm, or millivolt sources. It is available as a basic module, or in an explosion-proof housing with optional display and optical buttons for local configuration.

It’s configurable for hazardous locations, and offers a variety of advanced-performance features, including:

• Unique optical buttons allow operation through the glass of explosion-proof housing
• User-friendly interface with 5 lines of text or symbols in 7 languages
• Optional LCD display with selectable, programmable backlight
• Configurable bar graph and automatic selfcalibration
• Temperature range from -40°C to +85°C (-40°F to +185°F)
• Easy installation and mounting
