The SEM161 is a “smart” humidity transmitter sensor with a single two wire (4 to 20) mA output. The design uses a digital sensor which plugs into the sensor stem. A 4 digit display option is also available.

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 measure any one of these 4 parameters on the SEM161.

Configuration is performed quickly using our new 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.

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 100% RH.
