4.1 Assembly instructions
The choice of a suitable installation location depends on
various factors. Here, depending on the variables to be
monitored, module-specific instructions must be observed
(see Section 4.1.1 to 4.1.3). If variables are being
measured from different modules, the installation
instructions for all corresponding modules must be taken
into account.
4.1.1 Contact temperature measurement
The contact temperature is measured at the underside of
the BCM housing (see Fig. 4-1). The temperature
represents the contact temperature for the mounting
surface. For optimal thermal coupling the BCM must lie flat
on the mounting surface. To prevent small air gaps, a
thermoconductive medium should be used between the
surfaces.

4.1.2 Relative humidity and ambient pressure
measurement
These modules are only available for
BCM R15E- 002 -DI00-_ _ , _-S4.
The humidity and the ambient pressure are measured on
the upper side of the BCM housing. The sensor elements
are located below the membrane inside the housing (see
Fig. 4-2).

During use ensure that the membrane is not covered up
and that there is good air circulation.
Direct contact with spray water will falsify the
measurement.
Hold contact temperature stable for humidity
measurement.
