VEGAMET 841 Controller for one 4-20mA sensor input (Non-ATEX )

1 x 4-20 mA sensor input, 1 x 4-20 mA current output, 3 x operating relay (1 of which can be used as a fail-safe relay).

The VEGAMET 841 controller feeds a connected 4- 20 mA sensor, processes the measured values and displays them.

A large display for data visualisation is integrated in the housing designed for rough field conditions.

With a VEGAMET 841, tank level readings can be reliably monitored and displayed as level, volume and/or percentage full, and 1amp relays can be switched based on tank levels, e.g. for overfill protection alarm activation or pump/valve activation.

Integrated Bluetooth technology means the controller can be programmed, commissioned and troubleshooted quickly and easily via the free VEGATOOLS smartphone/tablet app or using a Bluetooth enabled PC with free VEGA software.
