Panel Meters, Indicators and Detectors

Chosen by input signal, supply voltage and cutout

Panel instruments get picked by what they read and where they sit: signal input, supply voltage, digit count and the cutout they were built for. Listings have covered a Newport 558B current loop digital indicator, a Westcon W3330-03S digital panel meter on 115 V AC, and an eight-digit ESAM DIS8MP indicator.

These are generally specific to the model they replace, because scaling and input configuration are set inside the unit rather than externally. Front labels and rear terminal blocks are visible in the photos so wiring can be confirmed before ordering, and returns run 30 days. Sensors feeding these displays are grouped under sensors and switches.
