Level sensor for monitoring the level of liquid media

Areas of application ► The level sensors are ideal for industrial use because of their extreme reliability and robust mechanical construction. They operate safely and reliably even under harsh service conditions and can be used in the following industries, among others:

• Plant construction • Food industry

• Biochemicals • Engineering

• Chemicals • Offshore

• Energy systems • Petrochemicals

• Natural gas • Shipbuilding

• Power stations • Pharmaceuticals etc.

Characteristics

► Level sensor output 4 – 20mA or

► Resistance output in three-wire

potentiometer circuit

► Temperature range: -30°C to 150°C

► Simple operating principle

Reed switch resistance measuring chain

► 12 mm accuracy grid

► Vertical installation

► Electrical connection:

Connecting box, coupler plug or cable

► IP66 protection

Functional description ► The magnetic field of a permanent magnet built into the float operates the resistance measuring chain

installed in the tube which is equivalent to a three-wire potentiometer circuit. The resistance signal generated

is proportional to the level.

The signal can be transmitted through external transducers and limit transmitters or through a 4-20mA two-

wire transducer (see brochure ZM1) which can be integrated in the level sensor connecting box.
