Schneider Electric releases Foxboro RTT15S optical temperature transmitter

October 26, 2016 — Schneider Electric has launched Foxboro RTT15S Optical Temperature Transmitters, a family of temperature transmitters that features a backlit LCD display with optical configuration buttons – operable through the glass cover of the unit’s explosion-proof housing – that enable users to locally configure and operate the transmitter even in hazardous locations without the need for process shutdown.

Designed to serve a wide range of temperature applications, Model RTT15S temperature transmitters are microprocessor controlled, use the HART version 5 or 7 communication protocols, and can receive input signals from thermocouples, resistance temperature detectors (RTDs), and ohm or millivolt sources. Their microprocessor-based electronics minimize ambient temperature effects while delivering accuracy, repeatability, and linearization of input signals. An automatic calibration routine continuously checks zero and full-scale outputs of these transmitters against factory-calibrated voltage signals stored in non-volatile memory. If needed, adjustments are made automatically without interrupting transmitter output signals.

In addition to three configuration buttons, the RTT15S optional LCD display offers a selectable red or white backlight, five lines of text or symbols, configurable bar graphs, intuitive menus, and scrolling help text in seven major languages – English, German, Spanish, French, Italian, Swedish, and Danish. The configurable backlight can be programmed to change colors or flash upon diagnostic error detection. In applications where the optional LCD display and explosion-proof housing are not required, the RTT15S is available as a basic module that can be configured remotely using PC-based Device Type Manager (DTM) software or a handheld controller. 

Other user-configurable features on the RTT15S family include low and high out-of-range values (between 3.5 and 23 mA); sensor error detection, with output values based on shorted and open sensor conditions; and direct selection of error detection using NAMUR 43 values. These features, together with a range of transmitter packages, high-durability sensors, and other options, make the RTT15S easy to mount, install, configure, and operate reliably for a long life.
Schneider Electric’s Foxboro Field Devices provide a broad range of measurement and instrument products, including solutions for pressure, flow, analytical, temperature, controlling, and recording.
