The Line Break Detection System type ELBS-10 is an electronic equipment, developed by Biffi,for monitoring the pipeline integrity. The ELBS-10 continuously monitors the pressure in the line and in case of failure, it sends a command to the actuator so as to stroke the line valve to the fail safe position. The electrical power necessary for working, is supplied by a 7.2V lithium battery pack that allows the ELBS-10 to work for at least one year.

The ELBS-10 is provided with a powerful local operator interface, made of one 2 lines / 16characters LCD display and 3 push-buttons, that allows to enter the configuration data and to visualise the values of variables or the status of the device. Moreover an RS232 serial communication port is provided for connection to a PC or LAP TOP, to carry out parameter configuration, or variables visualisation or to down-load the recorded event data for further analysis of pipeline behaviour .

The ELBS 10 was especially engineered for “ON FIELD” service, it means capability of working in the severest ambient conditions, as wide operating temperature range, vibrations, explosive atmosphere, etc. Particular care was taken to increase the level of immunity against the radio frequency disturbs.
