For continuous level indication Müller Industrie-Elektronik offers the level sensor MELS-F out of the product series Modular Economic Sensors. This MELS-F sensor provides the opportunity to output the fill level linear analogue with 4 to 20 mA and to configure two programmable switch-points. As a standard, the programming of the sensor can be done via LED-display as well as with keys. As one of a few sensors, the configuration is possible via a 4 to 20 mA current loop display with HART-protocol.
The level sensor has a head with display unit made of translucent Polycarbonate an integrated 4-digit current loop display and is programmable with three keys using innovative touchM sensing technology. By the use of the capacitive sensor technology the electronic components are sealed in the device housing where dirt, liquids or other external influences can do no harm and thus achieve protection class IP 67. As the head of the sensor can be rotated through 300 ° and the display is reversible by 180 ° for overhead mounting, the sensor fits into all local conditions. The electrical connections are available in several different plastic plug versions. All process connections are generally made of stainless steel 1.4571.
