4. CONNECTION OF THE TRANSDUCERS
Any ALMEMO
®
sensors can be connected to the ALMEMO
®
input sockets Mxx
of the plug-in modules (8) and (9). For connecting existing sensors it is only
necessary to connect a corresponding ALMEMO
®
connector.
4.1 Transducers
A detailed description of the comprehensive ALMEMO
®
sensor range (see
manual section 3) and the connection of existing sensors (see manual section
4) to the ALMEMO
®
instruments are provided in the ALMEMO
®
manual. All
standard sensors with ALMEMO
®
connector usually have the measuring range
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 Measuring Circuit Board ES 5590-G2 of the system ALMEMO 5990-1
has 10 input sockets with, at first, the meas. channels M0 to M9 being
allocated to them. However, ALMEMO
®
sensors can, if required, provide up to
4 channels so that 40 channels are available with 10 input sockets. The
additional channels can be especially used with humidity sensors with 4 meas.
variables (temperature, humidity, dew point, mixture ratio) or used for function
channels. If required, the sensor can also be programmed with several ranges
or different scaling or, depending on the pin assignment, 2 or 3 sensors can be
combined in one connector (e.g. TE/Ntc, mV/V, mA/V etc.).
The additional meas. channels of a connector are increased in steps of 10
(e.g. the first sensor has the channels M0, M10, M20, M30, the second sensor
has the channels M1, M11, M21, M31 etc.).
