Level transmitter

Block diagram


Our integrated circuits and reference designs enable you to build level transmitters with sensors that convert gathered measurement into an electrical representation. Transmission occurs over a loop-powered 4-20 mA interface, an IO-link interface or wireless connection.

Design requirements:

Level transmitter designs often require:

  • Precision signal chain for sensing.
  • Ultra-low current.
  • Multi-protocol industrial communication and interface solutions.
