Digital DDS Cleanroom Climate Sensor

The cleanroom climate sensors of the DDS series allow exact and long-term stable recording of the room climate parameters temperature and relative humidity. Thanks to the fully integrated acquisition electronics and the hermetically sealed sensor casing, environmental influences and drift effects are minimised. The direct digital connection to the Telemon Monitoring System ensures a loss-free and fail-safe transfer of the measured data. Alternatively, multiple, configurable legacy analogue outputs (0..10V, 2..10V, 4..20mA) can be realized by using a Niotronic signal transmitter (NTHS series). Temperature only versions without humidity sensor elements are available on request.
