Level sensor MG Level sensor for monitoring the level of liquid media 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 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. 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 twowire transducer (see brochure ZM1) which can be integrated in the level sensor connecting box.
