The Contrec 120A.2 is the wall-mount version of the 120A Level Monitor, housed in a weatherproof field enclosure with standard cable glands for installation right at the tank rather than in a control panel. It turns a standard 4-20mA analog level sensor into a clear, at-a-glance display of tank level and contents: a 20-segment LCD bar graph shows level as a proportion of the full span, while a separate 7-digit numeric display reads out contents in whatever engineering unit the installer chooses. Because it draws its power entirely from the 4-20mA loop it monitors, there’s no separate power cable to run to the field location.
For tanks that aren’t a simple straight-sided shape, a 25-point non-linear correction table lets the 120A.2 translate a raw sensor signal into an accurate volume reading even where level and contents don’t scale together evenly. Four programmable level alarms with open-collector outputs can drive external relays or indicators for high, low, or intermediate level conditions, and all configuration is retained in non-volatile memory. The weatherproof housing lets it be mounted directly at the tank for local operators to read.
