Description

Signal conditioning and display instrument for level sensors

Displays the measured values and gives simple control functions


Application area


Designed to be used in a variety of industries. The VEGAMET 381 is ideal for simple control tasks. The controller powers the connected 4 … 20 mA/HART sensor, processes and displays the measured values . Comprehensive adjustment functions enable individual adaptations to the respective application. 


Benefits


●    Highly readable LC display through digital and quasi analogue indication of the measured value
●    Transmitter power supply via the 4 … 20 mA sensor input
●    Flexible use through two relay outputs to control pumps and stirrers, etc.

Instruction

The VEGAMET 381 signal conditioning instrument powers a 4 … 20 mA sensor and processes its measured value. Through an adjustment on VEGAMET this measured value can be scaled individually and outputted to connected instruments via the current output. Beside the large indication there are two operating relays that serve as limit alarms for control tasks.

VEGAMET 381 is adjusted on the front via a clear LC display and a 16- step function switch as well as two keys.
