Series TTW Weatherproof Immersion Temperature Transmitter

Weatherproof Immersion Temperature Transmitter
Pt100 RTD, PC Programmable Transmitter

The SERIES TTW Immersion Temperature Transmitter combines three popular products into a single package. Our TBU series head mounted temperature transmitter is factory mounted into our A-709 enclosure. A Pt100 RTD version of our TE series is wired to the transmitter, giving insertion lengths up to 18". Each transmitter is factory programmed and calibrated to output a 4 to 20 mA signal proportional to the 32 to 212°F (0 to 100°C) temperature range.
