■■ Switch point adjustable when installed
■■ All connections already pre-assembled
Differential pressure gauge with pressure switch,
model A2G-90
Description
The model A2G-90 differential pressure gauge with pressure
switch is a combination of the Eco model A2G-05 differential
pressure gauge and the model A2G-40 differential pressure
switch, which have been fitted within a compact plastic case.
The case is made from plastic (ABS) and with all connections
built in. The cover is screwed on. All versions have an ingress
protection of IP65 (per EN/IEC 60529).
The A2G-90 is ideally suited wherever an analogue display
(e.g. for local control) and a switching output (e.g. for direct
connection to a higher-level controller) are required.
