Magnetic Level Transmitter

A magnetic level transmitter detects the position of a magnetic float through reed contacts and a resistor chain along a rod and converts it into a continuous analogue signal. The level read by eye on the indicator can then be sent to a PLC, SCADA or control panel.
It can be clamped to the chamber of a magnetic level indicator or mounted directly in the tank with its own float. The store range offers 1000 and 1500 mm models; the output can be taken as 4–20 mA or 0–10 V through a converter.
Main Applications
- Remote monitoring on tanks with magnetic indicators
- Continuous level on boilers and process tanks
- Level transfer to PLC and SCADA
- Fuel and chemical tanks with stock tracking
