In addition to our RA/FA series variable area flowmeters, SGK and NAV4A can also be fitted with MSK type limit switches.
Thanks to a guide slot in the protective sleeve, these limit value switches can be adjusted over the entire measuring range.
A knurled nut is used for fastening so that the switching point can be adjusted more quickly and easily.
In addition, the risk of damage to the limit value switch due to over-tightening is prevented.
For your installation site, this means that a torque spanner is no longer required to set the switching point.
More detailed information can be found in the installation & operating instructions in the chapter ‘Setting the limit value switches’ (e.g. for RA 60/FA60 section 7.2).
