ISOMAG® – ML155 retrofit unit for data acquisition, GPRS transmission
The ML155 is a retrofit unit which can be used for the GPRS transmission of several variables (up 5 measures) such as: pressure (up to 2 pressure inputs); flow rate (up 2 measurement points with pulse input or one point by a 2-wire analogical input); level (analogue input); temperature, etc. All these measures are logged in an SD-memory card for a total amount of memory up to 16 Gbytes.
The ML155 can be powered by batteries (up to 6 internal 3.6 V lithium batteries) and/or by mains power supply. When operating with mains power supply, batteries have the back up function, avoiding any loss in the measuring in case of power supply failure. The GPRS wireless transmission is performed by an internal 4-bands modem.
The ML155 is available with or without graphical display and with 3 programming keys. Housing material: Aluminium, AISI304. or further information, see the enclosed technical data sheet.
