Specification sheet Controller in field housing for a continuously measuring analogue level sensor Technical data Operating voltage ƲƲ Nominal voltage AC ƲƲ Nominal voltage DC Power consumption Application area The VEGAMET 841 controller feeds the 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. It enables simple implementation of pump controls, flow measurements on open channels and weirs and totalizers. With VEGAMET 841, limit values can be reliably monitored and relays can be switched, e.g. for an overfill protection according to WHG. Your benefit • Easy-to-read display from a distance, even in sunlight and darkness • Complex programming of control tasks is no longer necessary • Simple and reliable commissioning and diagnosis of the measuring points via smartphone Function The VEGAMET 841 controller can power the connected sensor and process its measurement signals. The requested parameter is shown on the display and also output to the integrated current output for further processing. The measurement signal can thus be transferred to a remote display or a superordinate control system. Operating relays for control of pumps or other devices are also integrated.

Specification sheet Adjustment Adjustment via the display and adjustment unit The adjustment of the VEGAMET 841 is carried out menu-driven via four front keys and a clearly arranged, graphic-capable display with background lighting. The VEGAMET 841 has an integrated display and adjustment unit. Alternatively, the parameter adjustment of the device can be done via Bluetooth and corresponding adjustment tools. Wireless adjustment via Bluetooth The Bluetooth version of the device enables wireless connection to smartphones/tablets (iOS/Android) or Windows PCs. Operation is via a free app from the...
