The NQL series of loop-powered instruments is now 10CFR50-B-qualified (a Nuclear Regulatory Commission requirement for nuclear power plants). The NQL consists of eight models that accept 4–20 or 10–50-mA input and displays the process variable in digital or digital/bargraph mode. Both LCD and LED versions are available and some models come with RS232E I/O. The new series is intended for replacement (or new installations) of analog meters where only the two-signal wires are available (no power source). The LCD versions come with automatic tricolor backlight. Four packages are available: 4.5-in. switchboard; 6-in. edgewise and 1.75-in. wide; 6-in. edgewise and 1-in. wide; and miniature 2.9 in. ×1.5 in. × 1.5 in. (digital only).OTEK Corp.
