SEM160I - Low Cost Humidity and Temperature Transmitter

Product Image

The SEM160i is a low cost 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 to 20) mA ) versions, the single channel version has a thermistor (optional Pt100) mounted in the sensor tip for direct temperature sensing by users.
 
A USB HID interface is provided for user configuration using USBSpeed-Link 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.

SEM161/2 - Humidity And Temperature Transmitters

Product Image

The SEM161/2 is a “smart” humidity transmitter with either 1 or 2 x (4 to 20) mA two wire outputs. 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 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 SEM161/2 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. 

DM650/HM - Humidity & Temperature Indicator With Data Logging, Alarm & Messaging

Product Image

The DM650HM is a battery powered humidity switch with built in sensors designed to display % relative humidity, temperature, dew point and delta temperature, on a 6-digit LCD display.

The instrument offers an advanced display mode allowing the user to also display one or two (1 to 32) character messages. Additional to the messages, the user may select an alert event to occur when the humidity is within a band. The change-over relay can be used together with the messaging and alert to provide switching at user set switch points. In addition to this,  an on board datalog function is also available to record process details at up to 5000 points. Wall and duct mounted versions are available
