1 Level Transmitter Construction The GEMÜ level transmitter has an immersion tube with reed contacts and a chain of resistors which are triggered by a float with an integrated permanent magnet. A threaded adapter and DIN/ANSI flanges for tank mounting are also available. The electrical connection is either via ready-made cable or connector. Features Continuous linear measuring signal Direct reading of medium level High-resolution reed contact measuring chain Simple installation Compatible with the digital multifunction device GEMÜ 1276 for optical indication and signal evaluation, e.g. limit s witch points Variable mounting positions Advantages The device is used for monitoring liquid levels of inert and corrosive media For applications with open, closed and pressurized tanks Materials: Choice of PVC-U, PP, PVDF, stainless steel Weight-saving construction Dimensions 25 Total length B Installation length A Ø 55 SW55 Ø 75 C D Table of dimensions see page 4
