Universal temperature sensors

The cooling volume sensors of DDS series enable highly accurate temperature measurement in refrigerators, freezers, cold rooms, as well as in liquid or gas-filled containers of any kind. The actual sensor element is thanks to double or triple rolling protected against any ingress of moisture. Thanks to the high-precision data acquisition (24-bit analog / digital converter), high accuracies over a very wide temperature range are guaranteed. The direct digital connection to the Telemon Monitoring System provides a lossless and interference-free transmission of the measured data. Alternatively, multiple, configurable legacy analog outputs (0..10V, 2..10V, 4..20mA) can be realized through the use of a Niotronic signal transmitter (NTHS). Versions for different measuring ranges with different sensor elements and cable lengths are available.
