Popis
The TX13 in-head mounting thermocouple transmitter converts a thermocouple input over a configured range to a standard industrial (4 to 20 mA) transmission signal. A simple push button operation allows the user to select thermocouple type, burnout direction, select fixed ranges and trim 4 and 20 mA points. The in-head transmitter incorporates the latest digital technology to ensure accurate drift-free performance.
The default factory scaling is for a range of 0 to 1000°C and Type K thermocouple input, with up-scale burnout. Upon request, we will set up a transmitter according to your specifications.
