With the 

meM-LOG-SE

, BMC 

Messsysteme GmbH introduces a 
data logger, that offers entirely 
new possibilities for many measur-
ing applications.  
 
It is a completely self-sufficient 
device, which is especially suitable 
for long-term measurements. 
 
 
Unlike a classic data logger re-
cording for a long time but with 
very low frequencies, the 

meM-

LOG-SE

 reaches 

 

... sampling rates of  

up to 100Hz ... . 

 
 
Equipped with an integrated ac-
cumulator, the 

meM-LOG-SE

 can 

be placed even in hardly accessible 
locations where neither any power 
supply nor PC connection is possi-
ble.  

So it is no problem, to realize 
measuring applications which 
require 
 

... mobility and flexibility ... 

 
in a high degree. In order to extend 
the operating time of the accumu-
lator, the device changes into an 
energy-saving mode after 1 minute 
(

Sleep Mode

) and just "wakes up" 

occasionally, e.g. shortly before 
scanning the next measuring value. 
 
 
Via  
 

... 16 analog input channels in 

the measuring range of 

±

5V ... 

 
with a resolution of 12 Bit or via  
 

... 2 digital input  

channels (TTL) ..., 

 
the measured signals are written to 
the 512kB-size memory. The chan-

nels to be saved can be defined 
explicitly.  
 
 
The scan usually proceeds until the 
memory is full. If 

Loop Mode

 is 

selected, however, the 

meM-

LOG-SE

 uses a loop memory 

where previous measuring values 
are overwritten as soon as the 
storage capacity is reached.  
 
 
In addition,  
 

... alarm values can be set ...  

 
for each channel separately. If 
measuring values are beyond this 
range, either all channels or only 
channels whose alarm values have 
exceeded the normal range are 
recorded with real time informa-
tion. When leaving the alarm area, 
storage is automatically interrupted 
(

Alarm Mode

). This is a great 

advantage for the  
 

..documentation of breakdowns.. 

 
Besides that, a  
 

... digital alarm output ... 

 
is provided as a high and a low 
active digital output channel and as 
a relay output so that in case of 
emergency e.g. machines are auto-
matically stopped or sirens are 
turned on.
