The Filter Minder LED display from Engineered Products is a panel or dash display designed to read sensor output voltage to help determine filter restriction or other conditions being monitored by a sensor. As voltage increases, a light bar progressively illuminates until reaching maximum condition or full illumination of the light bar.
The unit, available in square and round versions, is designed with memory to “remember” the highest condition even if power is turned off. The last LED flashes when maximum condition is reached. The display can be adjusted to off, dim and bright settings, and it can be reset to zero by pushing the reset button. Display will accept 6 to 30 volts input, and it can provide sensors with a regulated 5V signal.
