Manufacturer Discontinued
If you’ve tried to reorder a Moniteur valve position monitor or rotary limit switch lately, you already
know: Moniteur Devices has gone out of business. The Sentinel, Watchman, and Survivor lines
that sat on thousands of actuators across the Americas are no longer in production — and there’s no factory
behind the part number anymore.
Anything Flows supplied Moniteur for years, so we built the bridge. As an authorized Max-Air
Technology distributor, we cross-reference every discontinued Moniteur unit to a direct, in-stock
Max-Air limit switch box — same NAMUR mount, same switch types, equal-or-better certification.
The quick cross-reference
- Watchman (aluminum, NEMA 4/4X weatherproof) → Max-Air
45 Series - Survivor / Survivor II (thermoplastic, corrosive & washdown) → Max-Air
41 Series - Sentinel / Sentinel II (explosion-proof, Class I Div 1, NEMA 7/9) → Max-Air
48 Series - Series 71 / SS2 positioners (pneumatic, electro-pneumatic, smart) → Max-Air
Standard & Smart positioners (MAYT-3300/3400, HART)
Not sure which line you have, or working from a legacy part number like AMYB- or FMYB-? Our full cross-over
guide walks every Moniteur family to its Max-Air equivalent and lets you buy the matching series online.
