Magnetic Level Transmitter

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.

Which material? The transmitter must suit the magnet strength of the float used in the indicator; the measuring length is chosen to match the indicator’s centre-to-centre distance.

Advantages

Visual + Signal

  • Indicator and transmitter together

Retrofit

  • Fits an existing indicator

Continuous Measurement

  • Whole range, not just points

Standard Signal

  • 4–20 mA or 0–10 V

Construction and Design Features

  • Measuring rod with reed contact chain
  • Signal converter electronics
  • Clamps for fitting to the indicator
  • Cable junction box

Write the indicator’s centre-to-centre distance and required output; we will define the right transmitter length together.
