4.4.6 Humidity check
The sensor actively monitors the humidity level in its electronics compartment. The humidity level
can be read out at the M800 transmitter. This humidity value should always be below 25% as
otherwise there is a risk of condensation forming.
<Humidity in sensor body> is displayed in M800 transmitter in menu
<ISM --> ISM Diagnostics --> Sensor Monitor --> Humidity in sensor body.>
The moisture warning alarm is active when relative humidity in the sensor reaches 40%. A gener-
al alarm is active when relative humidity in the sensor reaches 50%. In such situations the des-
iccant must be exchanged immediately. Please contact your local METTLER TOLEDO representa-
tive for assistance.
METTLER TOLEDO recommends that the desiccant should, under all circumstances, be replaced
every year.
Notice: It may take from several hours to a day for the humidity level to return to an
optimal level. Removing moisture from the sensor's electronics compartment necessitates
servicing. Please contact METTLER TOLEDO for assistance.
Desiccant will absorb moisture from atmosphere when it left open. Always store desiccant in a
seal packaging/ container. Discard any unused desiccants when they are older than six months.
Do not change the desiccant when the pipeline is cold. There is a risk of condensate forming once
the sensor cover has been unscrewed. The desiccant should be changed when the pipeline is
warmer than the ambient air or when the temperature in the pipeline and the ambient temperature
are approximately the same, e.g. during production downtimes.
4.5 Storage
Please inspect the instrument immediately after receiving for eventual transport damages.
The sensor should be stored in a dry, clean and protected area until time of installation.
Storage for a reinstallation
If the sensor has been removed from the process, it should be thoroughly cleaned and dried.
It should be stored in a dry, clean and protected area until time of installation.
Shipment of the sensors
Please clean the instrument carefully before shipment (e.g. for revision / repair). Please use a fixed
packaging to protect the instrument against transport damages. In ideal case the original packag-
ing should be used.
Transportation and storage temperature: –10 ... +70 °C
Relative humidity: 0 ... 90% rel. (non-condensing)
4.6 Disposal
The disposal is to the responsibility of the user. Sensors contain electronic components
that require special disposal without any health hazard for humans, and with no risk of
harm for the environment.
Notice: Please observe the applicable local or national regulations concerning the
disposal of "waste electrical and electronic equipment".
