ATxRail Temperature Transmitter |
View
Large
|
The ATxRail is a 2-wire DIN rail mount temperature transmitter, microprocessor based designed for the flexibility of accepting mV, Pt100 and a variety of thermocouples as the input sensor. The ATxRail delivers a scalable linear 4-20mA output current proportional to the sensor temperature. User-friendly configuration software is provided for parameter setup, including sensor type, temperature range, filter, etc. |
