| WARNING The probe is not designed for use in hazardous environments with potentially explosive atmospheres. Make sure that no part of the probe is placed in a potentially explosive gas mixture. |
When planning the installation of the probe into the process, take into account the following recommendations:
- Apply adequate thermal insulation around the probe part and cable outside the process to minimize the ambient cooling effect through the metal probe and risk of condensation on the humidity sensor.
-
Let the probe cable hang loosely to prevent condensed water from running to the probe head. Avoid attaching the heated probe head in a way that conducts the heat away, as this may prevent the probe head from maintaining a temperature that is above dew point.
- Install the probe head close to the flow or in the flow to ensure that the probe will function correctly and to prevent the probe head from residing in standstill gas. A long distance between the probe head and the flow may also lead to slow response.
- Hydrogen flow cools down the probe head. Higher flow means greater cooling effect. You can adjust the cooling effect by changing the probe position in the flow.
