Connection of the Transducers

4. CONNECTION OF THE TRANSDUCERS
®
Any ALMEMO sensors can be connected to the ALMEMO
and M2 of the measuring instrument (6). For connecting existing sensors it is
only necessary to connect a corresponding ALMEMO

4.1 Transducers

A detailed description of the comprehensive ALMEMO
manual section 3) and the connection of existing sensors (see manual section
4) to the ALMEMO
standard sensors with ALMEMO
and dimension already programmed and can be immediately connected to any
input socket. A mechanical coding ensures that sensor and output modules
can only be connected to the correct sockets. Furthermore, each ALMEMO
connector has two locking levers that snap in when the insertion into the socket
is established and that prevent a disconnection caused by pulling the cable.
Both levers must be pressed on the sides for disconnecting the connector.

4.2 Measuring Inputs and Additional Channels

®
The ALMEMO
input sockets, M1 and M2. However, ALMEMO
provide up to 4 channels. The additional channels can be especially used with
humidity sensors with 4 measuring variables (temperature/humidity/dew
point/mixture ratio) or used for function channels. If required, the sensor can
also be programmed with several ranges or scalings or, depending on the pin
assignment, 2 or 3 sensors can be combined in one connector (e.g. rH/Ntc,
mV/V, mA/V etc.). The additional measuring channels of a connector are
located one level higher. As a result, the measuring instruments have the
following channel occupancy.
