    There are, however, ways of reducing the effects of temperature, humidity and vibration. The capacitive sensor of the DT301, that is located external to the process, is protected of external sources of heat by an enclosure with internal thermal insulation. Nevertheless, the transmitter should be installed in way to avoid to the maximum the direct exhibition to the ray’s run.
