Model LPB (Loop Powered Bargraph) from Otek Corp. is a 51 LED unicolor or multi-color bargraph that can be configured for 1, 3, or 5 pointers, or full bars. The unit is 4-20 mA powered and fits 1/4 DIN and switchboard cutouts. It puts only a 4.5-V burden in the loop, allowing for multiple units in the loop on the factory floor. The 51 segments provide a 2% resolution and accuracy indication of the loop’s value, and can be scaled within 30% of its factory setting of 0-100% from the front panel zero and span pots. Four grades of instrument are available: industrial, to specific Mil-specs, nuclear (10 CFR 50B), and intrinsically safe.
