TX Series

Transmitters for TS Series Platinum Sensors


The TX Series are temperature transmitters designed to provide a 4 to 20 mA signal proportional and linear to the sensed temperature.


• Temperature sensor input of either 100 or 1000 Ω platinum RTD • A variety of factory calibrated ranges • Able to be field calibrated with a minimum span of 25°F and a maximum span of 400°F – starting point no lower than -50°F and no higher than +375°F • Two or three-wire sensor inputs • Two-wire 4 to 20 mA linear output • Loop-powered • Superior level of radio frequency and electromagnetic interference rejection • Optimum flexibility and reliability
