The TX13 is a “smart” in-head transmitter that accepts thermocouple temperature sensors and converts sensor output over a conﬁgured range to a standard industrial (4 to 20 mA) transmission signal.

A simple pushbutton operation allows the user to select TC 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.

If required the desired range can be speciﬁed at the time of order, removing the need for user conﬁguration. If the range is not speciﬁed then the transmitter will be shipped with the default range of 0 to 1000°C (32 to 1832°F) Type K.
