Description
The device Hydrocont® LK with integrated analogue evaluation electronic is a compact hydrostatic transmitter for continuous measuring of filling levels in liquids at hydrostatic pressures from 0 up to 1 bar within pressure less container, at process temperatures from – 40°C to +100°C.
The use of a capacitive measuring sensor with ceramic membrane, allows the use in nearly all fields of industry.
Application fields are e.g. the measurement of levels in reservoirs, clarification basins, deep wells etc., but also the filling level measurement in closed containers at liquids, like e.g. water, waste water, solvents, oil, sludge, fat, cleaning liquids, etc.
Function
The device Hydrocont® LK is used for filling level measurement by measuring the hydrostatic pressure.
The device can be alternatively used as put in sensor that is sunken down into the liquid by the carrying cable and a suitable fastening, e.g. cable clamp fixing or screw plug or also be screwed-in from outside into the container wall.
