SEM160i RH & Temperature Transmitter

Brand: Status Instruments

The SEM160i is a single/dual channel RH and temperature transmitter for industrial and BMS/HVac applications. 

The unit can be supplied in single or dual channel ( two wire (4-20) mA ) versions, the single channel version has a thermistor mounted in the sensor tip for direct temperature sensing by the users. 

A USB HID interface is provided for user configuration using USBSpeedLink configuration software, allowing the user to select signal source and range for each channel.

The dual channel version has four switch set ranges for easy onsite configuration. 

The four ranges can be programmed individually to the customer’s requirement off site via the configuration software.

Single point alignment is provided for both temperature and humidity ranges. 

The configuration software also provides data readings together with a basic logger function for diagnostics. 

Wall and duct mount versions are available.
