Product Description

Electronet TT-22SD Series temperature transmitters are designed for reliable temperature measurement in industrial environments.
They accept input from RTD PT-100 sensors and convert the temperature reading into a standard 4–20 mA output.
The device includes a programmable switching output, high accuracy, and a bright LED display for real-time indication.
Built for both liquid and gas applications, it offers excellent durability with SS316 construction options.
