These indicating pressure gauges
with reed contact assemblies are designed to provide economical pressure monitoring, set-point indication and fast switching for low power electrical signals.
In addition to providing accurate indication of gas pressure, these 21/2 inch diameter gauges incorporate a magnetically actuated reed switch capable of
operating low voltage annunciators, lights or relays. They are commonly installed on regulators and manifolds to activate an external alarm (such as
