  • EAC Approval

The SEM203TC is a cost effective 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 push button operation allows the user to select TC type, burnout direction, select fixed ranges and trim the (4
and 20) mA points. If required the desired range can be specified at the time of order, removing the need for user configuration.

The thermocouple temperature transmitter can be ordered with any of our temperature probes and connection heads. We can supply temperature probe assemblies with the temperature transmitter included.

If you already know the specification you require, we can configure the product for you at no extra cost. Otherwise the range is not specified then the transmitter will be shipped with the default range of (0 to 1000) °C type K


The SEM203TC can be ranged against a probe held at high and low range values or by using a thermocouple
simulator representing the required temperature using a simple “teach” method. Burnout direction can
also be set using the same push button. A zero and span trim function is also incorporated into the SEM203TC to give maximum flexibility.

If a sensor wire is broken or becomes disconnected the SEM203TC output will automatically go to its user
defined level upscale or downscale and the LED illuminates.

The SEM203TC in head transmitter incorporates the latest digital technology to ensure accurate, low drift


If the SEM203TC detects the sensor is out of range, then a red LED will illuminate in the transmitter to alert the user that something is wrong.
