The SEM161 is a “smart” humidity transmitter with a 4 to 20mA output. The product will measure humidity, temperature, dew point and delta T (the difference between dewpoint and ambient temperature) values. Using our free software,  PC configuration allows you to output any of these 4 parameters onto the 4 to 20mA signal.  Configuration is performed quickly using our USB port driven configurator by connecting the transmitter to the configurator and following the software instructions. The software allows you to tag the device, set installation date and set output range. Either fixed ranges or your own custom ranges can be configured for all output types in °C or °F.  Visit the software page to download the USB Speed-Link software.

The 4 digit LED display option provides you with a visual indication of the process parameters.  The display may be set to indicate either humidity, temperature, dew point or toggle between all three parameters.  Using our popular SCH4 connection head, the SEM161 series can be ordered for duct, wall or remote sensor mounting. The product default setting is 0 to 50°C and 0 to 100% RH.
