Description

The model A2G-90 differential pressure gauge with pressure switch is a combination of the model A2G-05 differential pressure gauge Eco and the model A2G-40 differential pressure switch, which have been fitted within a compact plastic case.

The case is made from plastic (PC) and with all connections built in. The cover is screwed on. All versions have an ingress protection of IP65 (per IEC/EN 60529).

The A2G-90 is ideally suited wherever an analogue indication (e.g. for local control) and a switching output (e.g. for direct connection to a higher-level controller) are required.

Differential pressure gauge with pressure switch, model A2G-90

Special features

  • Compact indication instrument and pressure switch fitted within a plastic case
  • Single-pin microswitch (change-over contact)
  • Switch point adjustable when installed
  • All connections already preassembled
