The EMCO level transmitter, based on the magnetic floating principle, is used for remote indication and liquid level control.
Description: 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.
