Ideal for your industrial process applications, such as measure-
ment, dosing or environmental monitoring, the L452 is equipped
with 2 independent inputs. It allows you to connect various types
of sensors to the input in order to record varied data:
• 4-20 mA modules
• 0-10 V modules
These modules can also be used to record various data such as:
• temperature
• humidity
• air speed
For each of the channels, a real-time measurement is displayed on
the LCD screen. The L452 communicates via a USB input and the
Bluetooth function for configuration and data transfer onto a PC.
Specially designed for Chauvin Arnoux
®
Data Loggers, the control
panel for the data analysis software is a module fully integrated in
the Dataview
®
software, which has already proven its value.
The instrument can also be configured using its front panel, with a
very simple user interface. The menus are multilingual. Users can
lock the keypad with the PC software.
Alarms can be set on the various measurements. In counter mode, it
displays the measurement results in the unit selected (Wh, m.s, etc.).
The measurement campaign, which is programmable, can be
launched very simply using the L452’s keypad.
Its ergonomics makes it even simpler to use: magnetized rear panel,
Multifix system, desktop stand. It operates on rechargeable batteries
or the mains supply.
