Description
The EMCO level transmitter, based on the magnetic floating principle, is used for remote indication and liquid level control. The HS89 Analogue Level Transmitter consists of the following main parts: Float with magnet, measuring tube, and mounting flange with electronics. The measuring tube which is mounted on the top of the tank incorporates a number of resistors and reed switches. A float with a permanent ring magnet moves on the outside of the measuring tube. When the level changes, the magnet in the float will activate a reed switch which will connect a number of resistors, giving an ohmic value corresponding to the level. In the connection head a R/I transmitter is mounted and converts the signal into a standard 4 – 20 mA.
