For direct pressure indication at the measuring point and simultaneous switching of circuits for system control
The switching point can be adjusted in the centre of the viewing glass across the entire measuring range (280°C). If the pressure reaches the set limit, the contacts switch.
High switching reliability (30W/50VA) also in the event of vibrations
Only suitable if an imprecise switching point is sufficient (2-5% of set switching point)
Works without energy supply and, therefore, also in the event of power failure
Up to 4 switch contacts with NS 100 or NS 160, up to 2 switch contacts with NS 63
A solid front between measurement system and scale range prevents measuring media from escaping through the viewing glass e.g. following overload and has it escape through a pressure relief opening at the back instead
Available options are triangular front ring with bracket attachment, 3-hole front flange or attachment rim at the back
