Switch/gage

The Photohelic switch/gage from Dwyer Instruments measures and controls low air and compatible gas pressure. Now, with UL 508 listing and CSA certification, these units are available for OEM designers, panel builders and contractors who must have these agency approvals on electrical control devices.

The redesigned components include socketed, field-replaceable load relays rated for 10 A at 28 Vdc or 120/240 Vac, and 1/3 HP at 120/240 Vac. A new fire-resistant ABS terminal block employs binding head screws for all wiring connections. Improved circuit board design uses surface-mounted components.

New models are designated Series A3000 and are available in ranges from 0-.25 in. W.C. to 0-20 psig plus metric equivalents .
