Ideal for your industrial process applications, such as measurement, dosing or environmental monitoring, the L452 is equipped with 2 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.
Its ergonomics makes it even simpler to use: magnetized rear panel, Multifix system, desktop stand. It operates on rechargeable batteries or the mains supply.
