Bristol Instruments OMB 402UNI bargraph meters
The OMB 402UNI series of bargraph meters feature a 30-segment tri-color LED bargraph combined with a six-digit numeric display. Bargraph segment colors can be set to change when preset input values are reached. The series is designed with multi-function input capability. It can be programmed for dc voltage or current, RTD or thermocouple temperature sensors, process monitor or display unit modes. Mathematical functions, including peak, tare and linearization, also are programmable. The meters have 1/8 DIN-size housings with each bezel sealed to IP64 against ingress of water and dust. They are accurate to ±0.1% of range.
