ATxIsoBlock Temperature Transmitter |
View
Large
|
The ATxIsoBlock is a 2-wire in-head temperature transmitter with galvanic isolation between input and output, microprocessor based designed for the flexibility of accepting mV, Pt100 and a variety of thermocouples as the input sensor. The ATxIsoBlock 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, etc. |
