What is there to say about the Mac3 float switch? Well, firstly its shape is truly unique – the lack of any shoulders means it will pass easily through both clean water and water with small amounts of suspended solids. This shape also means the Mac3 is less likely to get caught up on potential obstructions inside a tank (so long as the cable is suitably installed.)
The original Mac3 is a simple but well-designed float switch for use primarily in clean water – but with its streamlined shape, is also suitable in water containing small amounts of suspended solids.
The flagship of the Mac3 float switch line, simply put – it just works! The Mac3 takes a float switch and refines the concept. There are no corners or sharp edges that can get caught on obstructions inside a tank or ragging points that cause irregular movement through a liquid. The polypropylene construction is both hardwearing and resistant to most fluids it is likely to encounter. Available in both the standard PVC and H07RN-F (rubber) cable types, the Mac 3 can be installed in almost any environment.
Mac3 Float Switch – the “go-to” for clean water pump protection
If I’m designing a pump setup, my first instinct is to reach for the Mac3! Then the only decision to make is the cable length and material (the go-to on my list would be the 2 meter, H07RN-F with a counterweight – MGM0206GB0C). With one of these, I can be sure that it will work in just about any situation that doesn’t require something a little more specialised.
The Mac3 can be installed as part of a controller installation (level or process control) or for dry-run protection on a pump. When wiring the Mac3 directly into a pump, I’d recommend using an IP68-rated T-joint connector (always in stock) to be sure there are no problems with the integrity of the connection. Though, there is no reason (if a suitable cable length is used) that the connection cannot be outside of the tank- with the Mac3 then being run into the tank itself.
