EUROSWITCH is going to launch a new version of their ESL analogue level sensor, specifically conceived for use in the Industry 4.0 environment.
The new range of sensors was designed by in-house R&D laboratories¸ an innovative structure in which Euroswitch continues to make considerable investments aimed at incorporating new communication protocols in Euroswitch products and providing a prompt response to increasingly demanding market requirements.
The newcomer is precisely the ESL level sensor with a 4-20 analogue output and two digital thresholds that are programmable by the user.  
A dedicated tool provided directly by Euroswitch allows users to programme both outputs at the switching point and reset point (thus providing 4 setting points available); the two outputs can both be the level outputs or one level and one temperature output, or both temperature outputs, using the built-in temperature sensor.
These innovative sensors incorporate advanced electronics that provides a communication system and an exchange of sensor-machine information through different protocols, such as Modbus and IO-link.
More precisely, IO-Link is a serial communication standard that allows the bidirectional exchange of data between sensors and the IO-Link master; a tool that in turn sends data to various networks, fieldbuses or backplane buses, making them accessible for immediate use or for conducting long-term analyses.
