SEM206/P

TEMPERATURE TRANSMITTERS SEM206 P SUITABLE FOR PT100 TEMPERATURE SENSORS (4 to 20) mA OUTPUT PC PROGRAMMABLE TEMPERATURE RANGE HIGH STABILITY FREE CONFIGURATION SOFTWARE INTRODUCTION The SEM206/P 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 new USB port driven configurator by simply connecting two clips to the SEM206/P loop terminals and following the software instructions. Calibration set up may be saved as a file on the PC for later use. The SEM206/P 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 100) C and upscale burnout.
