Magnetic Float Level Transmitter
รายละเอียด:
The magnetic float level transmitter device serves as a readings recorder for the electrical, continuous remote indication of the filling level. The operation of the measuring devices is based on the float principle. Through the wall of a guide tube the magnetic field, which is contained in the spherical or cylindrical float, triggers reed contacts, which uninterruptedly pick up the measuring voltage given at a resistance measuring chain. The measuring voltage is proportional to the height of the filling level ( 3-wire potentiometer circuit ). The size of the reed contacts is made up in different accuracy’s. In connection with a control unit the resistance value can be converted into a standardised analogue value,
e.g. 4 …20 mA.
