S70-1**, -2**, -3**, -4**Series
Screw mount vertical switch
Screw mount for installation from outside of tank
One, two, three, or four switch levels
Switch configurations of SPST or SPDT reed switch
contacts for high reliability
Enclosure Stainless Steel IP68 or Aluminium IP65
Safe area use only
All are custom built to suit particular applications,
based on information provided
The S70 series are vertical float switches
that are top mounted, via a screw thread
connection, from the outside of the tank.
Access to the inside of the tank is not
required for fitting the float switch.
These can be made with either 1, 2, 3 or 4
point level switches of either SPST or SPDT
action. The electrical loom is fully
insulated and encapsulated within the
stem of the device.
Designed to withstand the most arduous
applications, they are suitable for use in
Water, Diesel, Oil and hydraulic tanks and
reservoirs, as well as Chemical and Petrochemical storage and process control.
The float or floats follow the level of the
liquid and operate the SPST or SPDT switch
elements within the stem.

All are custom built to suit particular applications, based on information
provided. Please contact Cynergy3 with your requirements.
Information that is normally required:
The application and fluid in which the float switch will be used
That it is a safe area application
The Specific Gravity, SG, of the fluid
The maximum temperature of the fluid
Will the float switch will be fitted in a tank that is pressurised
The required thread size (If unknown we can specify)
The distance from the mounting face of the float switch to the switching
point or points. The switching action required at the switch points 'make on rise' or ‘make on fall'
