The RSF40 series is designed as a compact internal fitting device, with a wide range of options, making this ideal for size sensitive applications.

The RSF80 series is designed for external fitting, achieved with a 1/2” NPT taper thread. This avoids the need for access to the inside of the chamber and is ideally suited to applications where space or fitting time are prime considerations. They are manufactured in a variety of materials to suit most commonly used liquids. The switch action may be reversed by rotating the device through 180°. Typical applications are Diesel Level for Generators, Hydraulic Oil and Gearbox Oil Level.

The RSF10 series drop float has been designed to eliminate problems associated with limescale build up around the pivot point of a conventional float switch. It is also suitable in more viscous liquids, that might affect the pivot action of a standard float type. The drop float actuator allows the switch housing and float pivots to be located above the surface of the liquid and provides normally closed switch contact, opening as the liquid level rises.

The RSF20 is designed to eliminate the problems associated with limescale build up around the pivot point on a conventional float switch.This particular series is primarily for applications where a low level condition has to be monitored, in a system where the liquid is usually maintained at a high level,or where a wider differential is required between the opening and closing levels.

The RSF30 series is a range of higher power side entry, internally fitted devices. These may be used for directly switching some small loads of less than 100VA.Mounting of this series requires access to the inside of the tank. They are manufactured in Nylon or Polypropylene, with a choice of gasket materials, to suit most commonly used liquids. The switch action may be reversed by rotating the device through 180°.
