## **INTRODUCTION** 

The SEM206P is a cost effective “smart” in head transmitter that accepts PT100 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 Range, units and Burnout direction, without requiring calibration equipment. Configuration is performed quickly using our USB port driven configurator by simply connecting two clips to the SEM206P 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 100) °C and upscale burnout 

## **FEATURE HIGHLIGHTS** 

## **SENSOR REFERENCING** 

The SEM206P 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 SEM206P output will automatically go to its user defined level upscale or downscale and the LED illuminates. 

## **STABILITY** 

The SEM206P in head transmitter incorporates the latest digital technology to ensure accurate, low drift performance.
