SL121i
& SL121V Data loggers - Signatrol UK
SL121
Process Series
12 Bit Resolution! |
|
The SL121i and SL121v are low cost process input data loggers
with audible and visible alarms as well as larger memories.
Both data loggers are self contained, with internal batteries
that last up to 5 years. The data loggers are supplied with
a 1.5m long lead that connects directly to the connector on
the data logger and is terminated with crocodile clips for
connection into existing 4-20mA current loops (SL121i) or
to an appropriate Voltage measurement point (SL121v). The
SL121i is ideal for fitting into existing 4-20mA current loops.
Just break into the loop and clip the logger in place, instantly
adding a recording system to existing applications. Both versions
are electrically protected against reverse polarity connection
or over current / over voltage. |
|
The data loggers are configured using Signatrol's TempIT software
via an infra red reader that takes its power from the COM
port on the computer. The data logger can be programmed with
a user manifest that can be used to describe the application
that the data logger is being used to monitor. The TempIT
software allows the operator to graph in mA or engineering
units. Once configured, the data loggers are connected to
the 4-20mA loop or voltage point. At the end of the logging
period, the data logger is taken back to the computer and
the data downloaded. If the SL121i or SL121v is used, a green
LED is activated when the data logger is logging, changing
to red if the preprogrammed alarm levels are exceeded giving
instant indication that the logger has been subjected to physical
conditions outside those set by the operator. There is also
an audible alarm function to identify alarm conditions.
