## **INTRODUCTION** 

The SEM206TC is a cost effective “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. 

PC configuration allows the user to select TC type, Range, units and Burnout direction, without requiring calibration equipment. Configuration is performed quickly using a our new USB port driven configurator by simply connecting two clips to the SEM206TC loop terminals and following the software instructions. Calibration set up may be saved as a file on the PC for later use. 

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 type K 

## **FEATURE HIGHLIGHTS** 

## **SENSOR REFERENCING** 

The SEM206TC sensor referencing via the Windows based USBSpeedlink software allows for close matching to a known reference sensor eliminating possible sensor errors. 

## **SENSOR BURN OUT DETECTION** 

If a sensor wire is broken or becomes disconnected the SEM206TC output will automatically go to its user defined level upscale or downscale. 

## **STABILITY** 

The SEM206TC in head transmitter incorporates the latest digital technology to ensure accurate, low drift performance.
