Vega Controls VEGAMET 381 Signal Conditioner

VEGA CONTROLS VEGAMET 381

Function: The VEGAMET 381 signal conditioning instrument powers an individual 4 to 20 mA sensor (active mode) or takes an input from a device (passive mode) and processes its measured value. Through an adjustment on VEGAMET this measured value can be easily scaled by any factor and transferred to connected downstream systems from the current output. It has a large scaleable display (e.g for volume or mass), also 2 operating relays and a fault relay for control tasks.

Application: VEGAMET 381 can be teamed up with all transmitters on vega-line, it can provide power, a calibrated output, a display, 2 relay switch points and fault relay.

It can also be used as a signal conditioning and indicating instrument for simple regulatory and control tasks in all areas of industry and with any 4 20 mA sensor (active or passive).
